Who should opt for the Sony a7 III?
 
If you're looking to upgrade to a full frame camera and don't already have a large collection of Canon lenses, or otherwise want to get more serious about photography and prefer to skip on an APS-C sensor body, the Sony a7 III has a lot to offer, including a very reasonable price tag. Sony's IBIS (In-Body Image Stabilization) technology enables up to 5-stops of camera shake compensation with any lens that's mounted to the camera and represents huge advantage for the a7 III. Those shooting static subjects in low-light situations or when using a narrow aperture to obtain a desired depth of field, especially when a non-stabilized lens is mounted to the camera, will greatly appreciate the a7 III's sensor stabilization.
 
Are you a wedding photographer? The a7 III's dual memory card slots can protect once-in-a-lifetime images from being lost due to a corrupted memory card, and the camera's higher dynamic range could come in handy for events needing great exposure latitude. Another a7 III features that wedding/event/festival photographers will surely appreciate include is its significantly longer battery life compared to the EOS R.
 
Fast action shooters will be able to capture a higher percentage of peak-action shots with the a7 III's 10 fps burst rate with AF tracking compared to the EOS R's 5 fps under the same circumstances, while the camera's eye tracking AF will ensure that the subject remains properly focused. Note: The a7 III's continuous burst rate drops to 8 fps with viewfinder Live View (for easier subject tracking) in use.
 
Videographers who want to shoot slow motion video can utilize the a7 III's 120 fps Full HD frame rate to capture smooth, slow motion video with sound and AF tracking. The EOS R's resolution at 120 fps tops out at 720p and sound recording/AF tracking is not supported. Want to get the most out of your high quality, wide angle lenses when shooting in 4K? The a7 III samples the entire width of the full frame sensor when shooting in 4K, meaning your wide angle lenses produce an uncropped field of view, perfect for capturing expansive views. Recording in 4K on the EOS R, on the other hand, results in a 1.75x crop factor for your lenses. That means that a 16-35mm lens mounted to the EOS R produces a full frame equivalent field of view of 28-61.25mm in 4K mode.
 
Who should opt for the Canon EOS R?
 
If you're highly invested in the Canon EOS system but want to give mirrorless a try, getting the Canon EOS R will allow you to gradually build up a mirrorless kit, taking full advantage of the new RF lenses coming down the pipeline, while being able to fully utilize your existing DSLR lenses in the meantime.
 
Speaking of lenses, at this time, Sony has 43 FE lenses that can natively fit on the Sony a7 III. Of those, 25 cover the entire full-frame sensor. Other lenses (such as Canon EF) can be used on Sony cameras via adapters, but adapted lenses don't perform nearly as well as their native counterparts on Sony alpha-series cameras. However, while the currently announced pool of Canon RF lenses is small by comparison, Canon's EF-EOS R adapters allow nearly full functionality with EF/EF-S/TS-E and MP-E lenses (EF-S lens use results in a cropped recorded image). With Canon EF-series lenses performing similarly to RF lenses on the EOS R, the pool of lenses available for EOS R customers considerably increases. In fact, if you add up all the different EF/EF-S/TS-E and MP-E lenses which have been produced since the EF mount was introduced and add the announced RF lenses, you'd have more than 175 lenses to choose from, 149 of which cover the entire full frame sensor.
 
From an ergonomics perspective, the EOS R features a deeper grip and raised buttons that are easier to find without having to look at the body. The new Multi-Function Bar may take some getting used to (some may not like it), but many photographers will find the Control Ring found on the new RF lenses helpful for changing a preferred setting. For those used to glancing at a top LCD to check camera settings, the EOS R has you covered.
 
Landscape photographers can enjoy the benefits of the Canon Drop-in Filter Mount Adapter EF-EOS R with their EOS R to enable a circular polarizer or variable ND filter to be used with any of their EF-series lenses. With most ultra-wide angle lenses being incompatible with front filters, the Drop-In Filter Mount Adapter will prove to be a vital component of many landscape shooters' kits.
 
If you're a portrait shooter, you'll likely prefer the EOS R's faster AF performance in One-Shot mode compared to the Sony a7 III which defocuses/refocuses with every shot even if your subject hasn't moved. Those shooting portraits will also enjoy the bokeh-accentuating, shallow DOF (Depth of Field) capabilities that Canon's RF and EF mounts offer, including lenses featuring extremely wide f/1.2 apertures.
 
Vloggers and those shooting self-portraits will find the EOS R's vari-angle LCD much better for self-framing compared to the a7 III's tilt-screen.
 
* Canon claims a future firmware update will enable Eye AF with AI Servo mode.
 
Summary
 
The Canon EOS R and Sony a7 III are both incredible cameras at good-value prices and either can be a great option for most needs.

Who should opt for the Canon EOS R?
 
If you read our Canon EOS R vs. Canon EOS 5D Mark IV comparison, you'll recognize a lot of the benefits listed below. The reason is simple – many of the EOS R's benefits are unique to Canon's new mirrorless system, especially in regards to the R's use with adapted lenses, and those benefits remain the same when the camera is stacked up against any Canon DSLR.
 
The EOS R features an RF mount. Upon the camera's release, the selection of RF lenses will be relatively small (only four have been announced). While that may seem limiting, the truth is that the EOS R with its RF mount will be even more versatile than the EF-mount 6D mark II if adapted lenses are taken into consideration. With the Canon Mount Adapter EF-EOS R, Control Ring Mount Adapter and Drop-In Filter Mount Adapter, the EOS R is compatible with EF/TS-E/MP-E and – in a first for Canon full-frame cameras – EF-S lenses as well. So while the selection of RF lenses may be limited for the time being, the unique capabilities afforded by Canon's mount adapters will make the EOS R very attractive for several types of photographers.
 
Which photographers, precisely? Landscape photographers, portrait photographers and videographers will especially appreciate the benefits of the Drop-In Mount Adapter. How often do landscape photographers want to use CPOLs (circular polarizers) or ND (neutral density) filters with wide angle or ultra-wide angle lenses that are incompatible with front filters? Up until now, using filters with such lenses required the use of cumbersome 3rd-party front filter adapters. With the EOS R, those photographing the great outdoors can enjoy the benefits of a lighter camera body as well as a universal CPOL/vari-ND filter solution for their existing lens collection when traveling to their favorite sunrise location. Landscape photographers often want to stack a circular polarizer with an ND filter on a wide angle lens featuring front filter threads, but the resulting mechanical vignetting (and the increased likelihood of stuck filters) makes using the combo impractical. The Drop-In Filter Mount Adapter with Variable ND filter –with 1.5 - 9 stops of density – can easily be paired with a front-mounted circular polarizer like the B+W XS-Pro CPOL. A B+W XS-Pro CPOL will allow landscape photographers to cut through glare to capture dark blue skies and saturated foliage yet is thin enough not to cause mechanical vignetting on most wide angle lenses. And with a rear-mounted variable ND, a photographer can simultaneously reap the benefits of a long shutter speed to capture the movement of flowing water, clouds, rustling trees, etc.
 
The EOS R will be the better option to capture recitals, dance and theater performances with its absolutely silent shooting mode.
 
Those shooting portraiture will certainly appreciate the EOS R's Eye Detection AF, especially when a wide aperture prime lens is being used either natively or with an adapter. The EOS R's AF system is able to lock focus on and track subjects over a significantly larger portion of the frame compared to the 6D II's 45-point phase-detect AF system, allowing for greater flexibility in subject framing without having to focus and recompose. And because the EOS R utilizes the sensor for focusing, calibration issues associated with traditional phase-detect AF systems can be avoided altogether, better ensuring focus accuracy.
 
If a photographer's off-camera flashes are not capable of high-speed sync, the Drop-In Filter Mount Adapter with Variable ND can enable use of a shutter speed below the camera's x-sync speed (for the R, 1/200 sec.) while using flash and a wide aperture for great subject/background separation.
 
The EOS R can record video at 4K resolution while the 6D Mark II tops out at 1080p. Videographers can either use the extra resoltion to create highly detailed movies or otherwise create stabilized 1080p video and/or create panning movements within the 4K frame. Videographers can also make use of the Drop-In Filter Mount Adapter, especially when used with the variable ND to record video at optimal shutter speeds (typically, 2x the frame rate). With filters attached to the back of lenses, lens changes can occur more quickly (no need to unscrew/mount a separate ND filter) and the variable ND could easily replace numerous traditional ND filters in a filmmaker's kit.
 
Who should opt for the Canon EOS 6D Mark II?
 
There are benefits and drawbacks to Electronic Viewfinders (EVFs) and Optical Viewfinders (OVFs); neither will be best for/preferred by everyone. The 6D Mark II's viewfinder blackout time is actually shorter than the EOS R's viewfinder stutter during capture, making tracking laterally moving or erratic subjects easier with the OVF. If an optical viewfinder is preferred for any reason, the 6D II is, of course, the obvious choice. Other than that, the primary reasons to get a 6D Mark II are battery performance, preference for unadapted lenses and price. The EOS 6D Mark II's is rated for significantly more shots per battery charge compared to the EOS R. If you're often forgetting to charge and/or pack extra batteries, the 6D II may be the better camera for you. Those who simply don't like using adapters will also be better served by the 6D II. And finally, those whose budgets do not extend to the EOS R, especially when the cost of adapters are considered, may take advantage of the 6D II's slightly lower price tag (instant rebates may augment that difference from time to time).
 
Summary
 
The EOS R's ability to use adapted lenses, and the unique capabilities provided by the adapters, makes Canon's full-frame mirrorless introduction a camera you can effectively use now and well into the future, taking full advantage of all the new RF lenses headed down the pipeline. If compared to DSLRs, the EOS R's features position it somewhere between the 5D Mark IV and 6D Mark II, but certainly closer to the former than the latter. Without instant rebates in place, the price difference between the EOS R and 6D Mark II isn't all that much, even with a Mount Adapter EF-EOS R thrown into the mix. Therefore, most will find the EOS R's benefits to be well worth its incremental cost over the 6D Mark II's MSRP.

Who should opt for the Canon EOS R?
 
The EOS R is the first Canon camera to feature an RF [mirrorless] mount. And upon the camera's release, the selection of RF lenses will be relatively small (four, to be exact). While that may seem limiting, the truth is that the EOS R with its RF mount will be even more versatile than the 5D Mark IV with the tried-and-true EF mount if adapted lenses are taken into consideration. With the Canon Mount Adapter EF-EOS R, Control Ring Mount Adapter and Drop-In Filter Mount Adapter, the EOS R is compatible with EF/TS-E/MP-E and – in a first for Canon full-frame cameras – EF-S lenses as well. So while the selection of RF lenses may be limited for the time being, the unique capabilities afforded by Canon's mount adapters will make the EOS R very attractive for a lot of photographers.
 
Which photographers, precisely? Landscape photographers, portrait photographers and videographers will especially appreciate the benefits of the Drop-In Mount Adapter.

With filters attached to the back of lenses, lens changes can occur more quickly (no need to unscrew/mount a separate ND filter) and the variable ND could easily replace numerous traditional ND filters in a filmmaker's kit. Both the EOS R and 5D Mark IV sample the center of the sensor for 4K recording which results in a crop factor of 1.75x. However, the EOS R is compatible with EF-S lenses (the 5D Mark IV is not), meaning wide-angle framing does not have to be sacrificed.
 
For those on a limited budget, an EOS R costs significantly less than an EOS 5D Mark IV, even if you add the cost of an EF-EOS R adapter.
 
Who should opt for the Canon EOS 5D Mark IV?
 
The EOS 5D Mark IV has at least one very significant benefit over the EOS R – dual memory card slots. While the EOS R and RF 50mm f/1.2L and RF 28-70mm f/2L USM would seem to be an extremely good kit for wedding coverage, the R's single memory card slot means that a card failure could prove absolutely disastrous. For that reason alone, the 5D Mark IV will be a better option for recording once-in-a-lifetime moments.
 
Sports photographers will certainly appreciate the 5D IV's faster continuous burst rate with autofocus tracking for capturing the peak of action, although the R does have a significant edge in the RAW buffer department allowing for longer shooting at its rated speed.
 
There are benefits and drawbacks to Electronic Viewfinders (EVFs) and Optical Viewfinders (OVFs); neither will be best for/preferred by everyone. If an optical viewfinder is preferred, the EOS 5D Mark IV is, of course, the obvious choice.
 
While the EOS R's battery life is proving to be better in real-world shooting than its official specification would indicate, those shooting long events or in situations where battery changes aren't practical (such as heavy rain) may prefer the 5D Mark IV's higher expected battery life. Some photographers will appreciate the 5D Mark IV's built-in NFC and GPS features while others won't blink an eye at the EOS R's lack of them. Those using super telephoto lenses may also prefer the 5D Mark IV's larger size and increased weight to better balance out the camera/lens combination.
 
The 5D Mark IV also benefits from the refinements and reliability found in a mature product line, resulting in a very user-friendly, familiar interface that can be depended upon to work in even challenging conditions. Being Canon's first professional-grade full-frame mirrorless camera, with never before seen features (like the Mult-Function Bar), may take some getting used to and will ultimately have to prove its worthiness of the "refined camera" label.
 
Summary
 
The Canon EOS R and EOS 5D Mark IV were designed to be jack-of-all-trades and can be used effectively to capture... just about anything. The EOS R's ability to use adapted lenses, and the unique capabilities provided by the adapters, makes Canon's full-frame mirrorless introduction a camera you can effectively use now and well into the future, taking full advantage of all the new RF lenses headed down the pipeline. However, its lack of dual memory card slots (along with a few other differences) mean that the EOS 5D Mark IV will remain the better option for a sizeable number of photography professionals.

While many will appreciate the a7R III's higher resolution viewfinder and LCD panel, undoubtedly the most important difference between the two cameras is sensor resolution. The difference between 42.4 and 24.2 MP is substantial. If you're shooting subjects where resolving small details is a primary concern, or otherwise want the ability to heavily crop photos for better framing (or to extend the reach of a not-long-enough telephoto lens), then Sony a7R III's higher resolution sensor will be worth the incremental investment over the a7 III.
 
Who should opt for the Sony a7 III?
 
If you've been on the fence about investing in a Sony mirrorless camera and you don't need the massive resolution of the a7R III or the blazingly fast frame rate of the a9, then the Sony a7 III has your name on it. It may be positioned in the lineup as Sony's entry-level full-frame camera, but the only indication of the a7 III's entry-level status is its price tag. The a7 III's comprehensive assortment of advanced features will make it right at home in many pro, advanced hobbyist or weekend warror kits as a primary or backup camera. For what you get, the Sony a7 III is a bargain.

Who should opt for the Canon EOS Rebel T7i/800D?
 
If you are a current Rebel-series owner but want the benefits of a Dual Pixel CMOS sensor, and the size and weight of your current kit is a non-issue, then the EOS Rebel T7i/800D will offer a seamless transition with no adapters required to use your current set of lenses and a familiar button/control layout that feels right at home in your hands. With no adapter required for use with EF, EF-S, TS-E & MP-E lenses, there's one less vital piece of gear to be forgotten or malfunction. Just remember your fully charged battery and a memory card, throw your lenses in a bag and you're good to go (although we do recommend packing other items as well).
 
Note that the T7i has an optical viewfinder (OVF) while the EOS M5 has an electronic viewfinder (EVF), and both show up as advantages for their respective cameras. Depending on what you're shooting and what your preferences are, either one may be more beneficial than the other. Check out our OVF vs. EVF comparison here.
 
If you're interested in exploring off-camera lighting, the Rebel T7i offers an integrated Speedlite transmitter that will allow you to control off-camera Canon Speedlites remotely. To get the same functionality with the EOS M50, you would need a master flash (600EX II-RT / 430EX III-RT) or ST-E3-RT / ST-E2 transmitter, reducing the mirrorless camera's size/weight benefits.
 
The Rebel T7i's more sensitive AF system is able to lock on in lower light, and its battery will keep you shooting long after the EOS M50's battery has been exhausted.
 
Who should opt for the Canon EOS M50?
 
The EOS M50 represents a huge step up in image quality for those coming directly from a smartphone, and its size and weight will provide an easier transition into ILC (Interchangeable Lens Camera) photography compared to a traditional DSLR body. The EOS M50 will also be a great choice for current Canon DSLR owners who want a compact option that can also serve as a backup camera in a pinch (with the adapter) or otherwise want a reduced load for vacations, hiking or business trips, especially when one of Canon's EF-M series lenses will fit the bill perfectly.
 
Want to capture 4K video? The M50 has you covered (albeit without the benefits of Dual Pixel CMOS AF). If 1080p output is your goal, you can easily downsample 4K video (with very slight cropping on the right and left sides), crop the frame to provide a tighter angle of view, or even pan your FHD video within the confines of the 4K captured frame. You can also mimic zooming in and out of a scene to add even more production value to your 1080p movies. When not utilizing 4K capture, the M50 offers similar benefits as the Rebel T7i, including DPAF subject tracking.
 
On top of the size and weight advantages of an M-series kit, the M50's faster burst rate in single shot mode can help you capture the peak action as long as AF tracking is not needed for the specific situation. And if you prefer the benefits of an EVF (Electronic Viewfinder), then the M5 becomes the easy choice.
 
Summary
 
While the EOS M50 is a moderately capable camera with the size and weight benefits a mirrorless system brings, Canon's current [limited] EF-M lens selection may not provide all the flexibility desired in an ILC kit. And while Canon's complete EF/EF-S/TS-E/MP-E lenses can be used with an adapter, using lenses designed for DSLRs on a mirrorless camera negates much of its most alluring quality, its reduced size and weight.
 
On the other hand, the EOS Rebel T7i/800D, with its native ability to mount Canon's full range of EF, EF-S, TS-E and MP-E lenses, along with its higher battery life and built-in Speedlite transmitter, represents a simpler and more versatile platform on which to build a photography kit.
 
For those general purpose photography situations where a single, variable aperture zoom lens will suffice, the EOS M50 paired with an EF-M zoom lens can be a very convient option that will not be a burden to carry throughout the day. Note that as Canon releases more EF-M lenses, the versatility of an M-series kit increases along with the M50's appeal.

• Lower price

Who should opt for the Canon EOS M50?
 
Those wanting the smallest and lightest camera option, especially for backpacking or family vacations, Canon's mirrorless cameras pack DSLR-level image quality in a take-anywhere size. That the EOS M50 is compatible with Canon's similarly-small EF-M series lenses further bolsters this advantage. And while the M50 is technically more versatile from a lens options standpoint when the EF-EOS M Adapter is factored into the equation, use of the adapter with designed-for-DSLR lenses negates much of the small size and light weight benefits of an M50-based kit.
 
If you need a camera that shoots 4K, then the choice is easy – the EOS M50 shoots 4k, the EOS Rebel SL2/200D does not. Although you don't get the benefits of Dual Pixel CMOS Movie Servo AF in 4K mode, the ability to shoot 4K combined with the M50's vari-angle LCD and small size/weight will make it an extremely useful tool for filmmaking, especially for vloggers or one-man crews. If you appreciate the benefits of an EVF (Electronic Viewfinder), then the EOS M50 becomes the de facto option. However, note that I didn't list an EVF as a benefit for the EOS M50 nor did I list the OVF (Optical Viewfinder) as a benefit for the Rebel SL2/200D. Your own personal preferences and specific needs will dictate which viewfinder is most advantageous. Check out our article "Comparing Electronic Viewfinders to Optical Viewfinders" for more information. The EOS M50 also features a better/more sensitive AF system, more sensitive metering system, a faster continuous shooting burst rate and a larger buffer.
 
These features along with the camera's new .CR3 RAW file format (with space saving C-RAW support) result in an overall more versatile camera compared to the EOS Rebel SL2/200D.
 
Who should opt for the Canon EOS Rebel SL2/200D?
 
For those who tend to occasionally forget to pack important items in their gear bag, an advantage of the SL2/200D is its native compatibility with all of Canon's EF, EF-S, TS-E and MP-E lenses (no adapter required). Those needing to control larger lenses on their camera and those actively using the camera for substantial time periods will appreciate the SL2/200D's more substantial grip and longer battery life. The Rebel SL2/200D's larger exposure compensation range can certainly come in handy under extreme exposure conditions.
 
The Rebel SL2 has one particular advantage that nearly every photographer can appreciate – a lower price tag compared to the M50.

The Canon EOS M50 and EOS M100 cameras represent the budget options in Canon's mirrorless lineup, but the "budget" label is a relative one because – as Canon's naming conventions suggest – these cameras are not on the same level. Typically speaking, Canon camera models with more numerical digits in their name are positioned lower in the camera lineup than cameras with fewer digits. In this case, the naming convention holds true. The EOS M50 has several features not included in the M100, the most notable of which is an EVF (Electronic Viewfinder). The big question becomes, are the M50's features worth spending more for?
 
Let's take a look at how the EOS M50 and EOS M100 compare to find out which camera might be the best for your specific needs.

• Lower cost

Who should opt for the Canon EOS M50?
 
If you need a versatile, mirrorless camera and would like to shoot 4K, then the choice is easy – get an EOS M50. It's the only Canon mirrorless option (at the moment) that can record 4K video. Although you don't get the benefits of Dual Pixel CMOS Movie Servo AF in 4K mode, the ability to shoot 4K combined with the M50's vari-angle LCD and small size/weight will make it an extremely useful tool for filmmaking, especially for vloggers or one-man crews. For those who prefer viewfinder shooting, once again, the choice is easy. The M50's OLED EVF is well designed and makes it much easier to use when shooting in bright sunlight. The EOS M50 also features a flash hot shoe, better/more sensitive AF system, more sensitive metering system, a faster continuous shooting burst rate, exposure bracketing and more AWB options. These features along with the camera's new .CR3 RAW file format (with space saving C-RAW support) result in a camera that is simply more capable of capturing compelling imagery compared to the EOS M100.
 
Who should opt for the Canon EOS M100?
 
Of the limited number of advantages the EOS M100 has over the M50, the two which will likely prove most compelling for most will be its lower cost and smaller size/lighter weight. If your budget does not extend to the M50, you need the absolute smallest and lightest Canon mirrorless option available or you don't anticipate utilizing the M50's extra features, the M100 is there for you.

Who should opt for the Canon EOS M6?
 
Like the EOS M5 vs. M50 Comparison, the feature gap between the EOS M6 and the EOS M50 is quite narrow, relatively speaking.
 
If you're a seasoned photographer who appreciates having a myriad of easily accessible controls, then the M6's Exposure Compensation, Quick Control and Rear Control Dials could tip the balance in its favor. To see what I mean, flip between the two cameras in our Camera Top View Comparison. The two most prominent M6 features you'll likely notice are the Exposure Compensation and Quick Control dials, both of which are missing on the M50. Also absent on the M50 are the M6's custom shooting modes, located on the Mode Dial.
 
Every photographer will benefit from the M6's longer battery life. Many will also appreciate the M6's larger RAW buffer and plentiful remote options.
 
Who should opt for the Canon EOS M50?
 
If you prefer shooting with a viewfinder as opposed to framing your scene via the camera's LCD screen (or purchasing an optional viewfinder accessory which renders the camera's hot shoe unusable), then the EOS M50 is your camera. The M50's feature set will make it especially handy for vacations, social gatherings and general purpose photography and videography. With its advanced and more sensitive AF system, capturing in-focus images of human subjects – even in low light – will be easier. Although you don't get the benefits of Dual Pixel CMOS Movie Servo AF in 4K mode, the ability to shoot 4K combined with the M50's vari-angle LCD and small size/weight will make it an extremely useful tool for filmmaking, especially for vloggers or one-man crews. If outputting to 1080p video, set a tripod-mounted M50 to record 4K video and then pan around the frame in post for high quality b-roll, or otherwise reap the benefits of automatic and smooth Dual Pixel Movie Servo AF when recording 1080p video (the latter benefit is identical to the M6).
 
Summary
 
As we mentioned in the beginning of this comparison, these cameras are very similar. While their names may suggest a clear hierarchy, the cameras' feature sets belie simplistic categorization. Both cameras will likely serve most interested consumers very well, with the handful of differences above – and the benefits they bring to select shooting conditions – will ultimately determine which camera fits one's needs best.

Primary Advantages of the Canon EOS Rebel T7/2000D
 

• Smaller Size: 5.08 x 3.99 x 3.06" (129.0 x 101.3 x 77.6mm) vs. 5.16 x 3.93 x 3.00" (131.0 x 99.9 x 76.2mm)
• Lighter Weight: 16.75 oz (475g) vs. 18.77 oz (532g)
• Lower cost

If you glance at the specifications comparison found on this site, you'll likely notice that the Rebel T7 features a faster pop-up flash recycling time compared to the Rebel T7i (2 sec vs. 3 sec), which would seem to indicate an advantage. However, the T7 has a faster recycling time because it has a lower power flash. When fired at the T7's full power level, the T7i's recycling time will likely be similar.
 
Who Should opt for the Canon EOS Rebel T7i/800D?
 
When describing the customers who may be best served by the cameras in one of our comparisons, we typically start with the higher-end option as its versatility will make it an overall better option for most consumers. In this case, the feature difference between the cameras is so substantial and the advantages so one-sided that there is really only one reason to choose the Canon EOS Rebel T7 over the Rebel T7i – a lower price tag.
 
The Rebel T7i's Dual Pixel CMOS AF sensor, more advanced/sensitive AF system, higher burst rate/larger buffer and longer battery life could all be considered justification for the camera's higher price tag when considered individually. Put all those features together and the value you receive for the T7i's incremental price over the T7 is monumental.
 
Who Should opt for the Canon EOS Rebel T7/2000D?
 
As previously mentioned, the primary reason to opt for the EOS Rebel T7/2000D is for its lower cost. The Rebel T7 will be more than adequate for capturing high quality imagery under normal / not-so-challenging conditions, and those stepping up from smartphone photography will certainly appreciate the benefits of a significantly larger sensor and the ability to change lenses. And speaking of lenses, for the price of a Rebel T7i + EF-S 18-55 IS STM kit, you could get a Rebel T7 + EF-S 18-55 IS II, EF 50mm f/1.8 STM and EF-S 24mm f/2.8 STM lens.
 
Beginner/novice photographers aren't the only groups that will appreciate the Rebel T7's lower price tag. Advanced photographers wanting to capture images in high-risk-of-damage situations can more easily justify the sacrificial cost of a Rebel T7. Such photographers can mount the T7 to a car, motorcycle, bicycle, boat, etc. to capture dynamic imagery without risking damage to their primary camera(s).
 
Summary
 
Few camera comparisons are a clear-cut as this one. The Canon EOS Rebel T7i's superset of features will make it a more versatile imaging platform for those who can afford its price difference over the Rebel T7. But for those whose budgets don't extend that far, especially beginner/novice photographers, the Rebel T7 offers a solid step-up for those currently shooting with smartphones and/or point-and-shoot cameras who want to experience the benefits of interchangeable lens camera photography first-hand.

In September 2016, Canon announced its flagship M-series camera, the M5. Almost 18 months later, Canon announced the M50, a more-similar-than-different camera with a feature many M5 customers craved – 4K video recording. Even though the M50 is positioned lower than the M5 in Canon's M-series lineup, I think you'll be surprised to see just how close these cameras are to one another. Instead of siblings divided by years, they're more like fraternal twins.
 
Let's look at these two mirrorless camera offerings from Canon to see which might represent the best camera for your kit.
 
Canon EOS M5 and M50 Shared Primary Features:
 

• Dual Pixel CMOS AF Sensor*
• Resolution: 6000 x 4000 pixels (24 MP)
• Crop Factor: 1.6x (APS-C sensor)

• More White Balance Options: ambience/white priority vs. ambience only
• Faster Continuous Shooting: 10 fps (7.4 fps with Servo AF) vs. 9 (7 with Servo AF)
• Vari-angle LCD vs. tilting only
• Lower cost

Who should opt for the Canon EOS M5?
 
Unlike many of our comparisons, the feature gap between the EOS M5 and the EOS M50 is quite narrow, relatively speaking. However, there are a few differences between the two cameras that may prove pivotal in one's decision making process.
 
If you're a seasoned photographer who appreciates having a myriad of easily accessible controls, then you'll really appreciate the M5's user interface. To see what I mean, flip between the two cameras in our Camera Top View Comparison. The two most prominent M5 features you'll likely notice are the Exposure Compensation and Quick Control dials, both of which are missing on the M50. Also absent on the M50 are the M5's custom shooting modes, located on the Mode Dial.
 
Those shooting in cold conditions will certainly benefit from the M5's wider environmental operating range and longer battery life. Many will appreciate the M5's higher resolution LCD, larger RAW buffer and plentiful remote options.
 
Who should opt for the Canon EOS M50?
 
In short – everyone else. The M50's feature set will make it especially handy for vacations, social gatherings and general purpose photography and videography. With its advanced and more sensitive AF system, capturing in-focus images of human subjects – even in low light – will be easier than ever so you can focus less on photography and more on the time spent with family and friends. Although you don't get the benefits of Dual Pixel CMOS Movie Servo AF in 4K mode, the ability to shoot 4K combined with the M50's vari-angle LCD and small size/weight will make it an extremely useful tool for filmmaking, especially for vloggers or one-man crews. If outputting to 1080p video, set a tripod-mounted M50 to record 4K video and then pan around the frame in post for high quality b-roll, or otherwise reap the benefits of automatic and smooth Dual Pixel Movie Servo AF when recording 1080p video (the latter benefit is identical to the M5).
 
Summary
 
As we mentioned in the beginning of this comparison, these cameras are very similar. While their names may suggest a clear hierarchy, the cameras' feature sets belie simplistic categorization. Both cameras will likely serve most interested consumers very well, with the handful of differences above – and the benefits they bring to select shooting conditions – will ultimately determine which camera fits one's needs best.

With the release of the Sony a7R III, many may be wondering how Sony's latest high-resolution full-frame mirrorless camera stacks up against Canon's latest 5-series camera, the EOS 5D Mark IV, and which camera might suit their needs best. So, let's dig into the details and find out.
 
First, let's take a look at some differentiating specifications between the two cameras.
 

	Canon EOS 5D Mark IV	Sony a7R III
Resolution	30.4	42.4
AF Type	TTL secondary image-forming phase-difference detection system with Dual Pixel & AF-dedicated sensor	Fast Hybrid AF (phase-detection AF/contrast-detection AF)

Memory Card Slots	Dual Slots: CompactFlash Type I (UDMA 7 compatible); SD/SDHC/SDXC and UHS-I	Dual Slots: Memory Stick PRO Duo/PRO HG-Duo/Micro M2, SD/SDHC/SDXC

Looking at the specifications alone, the Sony a7R III appears to one-up the Canon EOS 5D Mark IV in almost every major spec category (differences in memory card formats aside). However, the specifications only tell a part of the story; other factors must be considered before deciding between these two cameras.
 
Size, Weight and Battery Life
 
As indicated by the table above, the Sony a7R III is smaller and lighter than the Canon 5D Mark IV, traits that many will appreciate. But, there are drawbacks to the a7R III's smaller size and lighter weight.
 
The first drawback is that the smaller design leads to a smaller battery, which in turn results in a shorter battery life. The second drawback is that the smaller design can also lead to an uncomfortable grip for those with medium-sized hands (or larger) when using the a7R III with many pro-grade lenses.
 

The Sony a9 is shown above with the Sony FE 70-200mm f/2.8 GM OSS Lens; the grip is nearly identical on the a7R III.
 
The Sony a7R III's smaller size and lighter weight will surely be appreciated by those who must hike significant distances to their desired photo locations. And for those shooting landscapes with a tripod, the comfort of a camera's grip may be a low priority. But for those shooting weddings, festivals or events – situations requiring that the camera be handheld for long periods of time – may appreciate the 5D Mark IV's more comfortable grip as well as its roughly 50% longer battery life.
 
Viewfinders
 
Viewfinder implementations differ significantly between the Canon EOS 5D Mark IV and the Sony a7R III, where the Canon body offers a traditional optical viewfinder (with customizable overlays) and the Sony body features an electronic viewfinder. Each type of viewfinder has benefits and drawbacks compared to the other (such as an EVF's elimination of viewfinder blackout times), and Bryan shared his thoughts on the advantages/disadvantages of electronic/optical viewfinders in his article, "Comparing Electronic Viewfinders to Optical Viewfinders". Be sure to check out the preceding information to determine which of these systems you may prefer.
 
Durability & Reliability
 
The time span between Canon's first 5-series camera to its latest iteration, the Mark IV, was 11 years (2005 - 2016). The time span between Sony's first a7R and the introduction of the a7R III was 4 years (2013 - 2017).
 
Canon rates the 5D Mark IV's shutter at 150,000 actuations; Sony claims the a7R III can withstand 500,000 actuations. If both companies are using similar procedures for determining shutter reliability, then Sony's significantly higher shutter rating will be comforting.
 
The Canon EOS 5D Mark IV and the Sony a7R III are solidly built and both are billed as "weather resistant" cameras. However, Canon has had significantly more time to refine their camera design for optimal protection from water and dust. We didn't test the thoroughly test the cameras' weather resistance, but we'd personally feel more confident shooting with the 5D Mark IV in adverse conditions.
 
Autofocus Performance
 
Sony's mirrorless cameras' AF performance has dramatically improved over the last couple of years, resulting in the gap between mirrorless and traditional DSLR AF performance quickly diminishing. But while the Sony a7R III focuses faster in one shot mode compared to its predecessor, it still isn't as fast as the 5D Mark IV. That's because the a7R III must defocus in order to obtain focus, causing a noticeable delay even when little has changed in the scene between shutter clicks.
 
In AF tracking mode, both cameras perform similarly well (either in viewfinder mode or LCD/Live View focusing).
 
Menu System
 
Having used Canon cameras for a number of years, we've grown acclimated to Canon's logical, easy to use menu system. Unfortunately, the Sony a7R III menu system seems needlessly complicated with 45 subtabs under the 5 main tabs. That Sony has included a customizable "My Menu" option has helped, allowing for quick access to your most-used menu items. Even so, we still greatly prefer the Canon menu system.
 
Video
 
While both cameras allow for 4K recording at 30p, there are some distinct differences between the cameras' video features. First, the 5D Mark IV records 4K video in .MOV (Motion JPEG) format with a crop factor of 1.74x; the a7R III in XAVC S:MPEG-4 AVC/H.264 using the full senor width (no crop). This difference alone may be the deciding factor between the two cameras if wide angle, 4K video is a top priority for you. The Sony camera is also capable of recording Full HD (1080p) video at 120 fps, while the Canon DSLR tops out at 60 fps.
 
Video shooters will also love the Sony a7R III's built-in 5-axis stabilization, allowing for smoother video recording regardless of the lens that's attached, as well as its tilting LCD screen for odd-angle shooting. The a7R III also features S-LOG 3 and HLG (Hybrid Log Gamma) Picture Profiles, while Canon Log is only available as an add-on (more expensive) upgrade for the 5D mark IV.
 
Customer Support
 
Canon is widely recognized as having an excellent support system, including (not not limited to) Canon Professional Services, the division which specifically caters to those who make a living with their imaging gear. The support we have received from Canon USA and Canon Professional Services has over the years has been very good. Canon USA's Customer Service Technicians have been eager to help and knowledgeable when we have needed phone support, and our experience with Canon's repair department (in the few times we've needed a repair) has been equally satisfying.
 
On the other hand, Sony is still in the building process when it comes to customer support for their E-mount camera system. As such, they don't necessarily have a reputation for exemplary customer service [yet, though things seem to be getting better].
 
Price
 
At the time of this comparison, the Sony a7R III's retail price is roughly $300.00 less expensive than the EOS 5D Mark IV, not counting instant rebates which can make the cameras much closer in price. But when considering the cost of the camera, it's also wise to think about the cost of the whole camera kit you may be considering.
 
Therefore, let's take a look at two comparable kits based on the two cameras.
 
Sony a7R III
Sony FE 16-35mm f/2.8 GM
Sony FE 24-70mm f/2.8 GM
Sony FE 70-200mm f/2.8 GM OSS
Total MSRP: $10,192.00
 
Canon EOS 5D Mark IV
Canon EF 16-35mm f/2.8L III USM
Canon EF 24-70mm f/2.8L II USM
Canon EF 70-200mm f/2.8L IS II USM
Total MSRP: $9,696.00 ($8,996.00 with current rebates)
 
Of course, MSRP values and the availability (and values) of instant rebates can change over time (possibly changing the advantage), but the above represents a current advantage of the Canon kit. Interesting is that the difference in weight between these two kits is only 9.6 oz (272 g), with the Canon kit being slightly heavier.
 
Wrap Up
 
There's no doubt that you can use either of these cameras in a professional setting to create high quality images or video. If you primarily shoot video, though, the Sony a7R III's advanced video features will likely make it the best overall choice for your needs. And, if you aren't heavily invested in the Canon ecosystem already, choosing the a7R III may make a lot of sense.
 
However, if you already have a decent Canon camera kit and you're not primarily a video shooter, I'm not convinced that the Sony a7R III offers enough advantages over the 5D IV to justify the cost, time and energy of completely switching brands. In which case, the Canon 5D Mark IV would most likely be the better option.
 
Note: Because of the performance limitations experienced when using Canon lenses on Sony cameras (via adapters), we don't consider that to be a viable solution (yet) for most serious photographers.
 
So what are the differentiators that keep you from switching from one of these cameras to the other? Let us know in the comments.

With the recent release of the Sony a7R III, many may be wondering, "Should I get the a7R III or get the less expensive a7R II instead?" That's a very fair question, and that's why we're going to be looking at how these two MILCs (Mirrorless Interchangeable Lens Cameras) stack up against one another.

Who should opt for the Sony a7R III?
 
Those who wish to capture high resolution sports imagery will immediately appreciate the Sony a7R III's twice-as-fast burst rate (10 fps vs. 5), image grouping display, upgraded AF system and [possibly] the new anti-flicker shutter timing (it may work better under some conditions than it worked in our tests). Those using the a7R III for professional filmmaking will likely benefit from the ability to record 1080p video at 120 fps, the upgraded AF, improved peaking and the S-LOG 3 and HLG (Hybrid Log Gamma) Picture Profiles.
 
Wedding photographers will enjoy the added security of the a7R III's dual memory card slots, and sharing images immediately on social media will be made easier with built-in Bluetooth.
 
Regardless of one's specialty, the upgraded IBIS system providing an extra stop of assistance to help keep images sharp will surely be appreciated by almost all photographers. The same sentiment holds true for the a7R III's increased battery life.
 
Who should opt for the Sony a7R II?
 
As is typical of successor vs. predecessor camera comparisons, the primary reason to recommend the purchase of a camera's predecessor – in this case, the Sony a7R II – is the older camera's lower cost. And in this case, the trend continues, with the a7R II weighing in with a 25% discount (with instant rebates) compared to the a7R III.
 
Landscape, architecture/real estate and studio photographers, in particular, who don't necessarily need a better AF system or a faster burst rate, will have fewer reasons to invest in the a7R III's upgraded features as the a7R II's sensor provides similar, high image quality. That said, the brighter viewfinder and longer battery life of the a7R III will be welcomed even by these groups.

• Approx. 1210 frame battery life vs. 900
• 400,000 shutter durability rating vs. 150,000
• Better weather sealing

Primary advantages of the Canon EOS 5D Mark IV over the EOS-1D X Mark II:
 

• 30.4 MP vs. 20.2
• Smaller & Lighter: 5.93 x 4.58 x 2.99" (150.7 x 116.4 x 75.9mm), 31.4 oz (890g) vs. 6.22 x 6.6 x 3.25" (158.0 x 167.6 x 82.6mm), 53.97 oz (1530g)
• Full touch-screen LCD interface vs. limited touch-screen
• Built-in Wi-Fi & NFC vs. N/A (Wi-Fi requires Wireless File Transmitter WFT-E6A, WFT-E8A accessory)
• Lower price

Who should opt for the Canon EOS-1D X Mark II?
 
If you are a photographer primarily interested in capturing fast-action sports, the EOS-1D X Mark II's blazingly fast 14 fps burst rate and huge 170 frames RAW buffer (in our tests, the buffer was actually only limited to the CFast memory card's capacity) will help you capture the optimal moment(s) when the action is at its peak. And if your sporting event is held in inclement weather, the 1D X II's extra weather sealing will certainly be appreciated.
 
If you're primarily a studio photographer who doesn't need more than roughly 20 MP of resolution, the 1D X II's gigabit Ethernet port is a great asset for tethered shooting.
 
Those using their DSLR to capture video will appreciate the 1D X II's 4K recording at 60 fps, although the larger body may prove cumbersome in some setups. A benefit for some filmmakers (and a drawback for others) is the 1D X II's approximate 1.3x focal length crop factor utilized in 4K video recording allowing for wider angles of view to be captured at the same focal length compared to the 5D Mark IV featuring a 1.74x crop factor.
 
Nearly every photographer can benefit from the 1D X II's higher resolution metering sensor, and AF point-linked Spot metering feature (very helpful) is only available on 1-series bodies. The ability to change focus screens is another benefit of the 1D X II that could prove important for some photographers.
 
Who should opt for the Canon EOS 5D Mark IV?
 
If you need more resolution than the EOS-1D X Mark II offers, require built-in Wi-Fi/NFC, prefer a smaller and lighter camera body and/or your budget simply does not extend to the level of a 1-series body, the EOS 5D Mark IV will likely prove to be a great choice.
 
Sharing many important primary features with the EOS-1D X Mark II (with reasonable compromises on others), the EOS 5D Mark IV is the second-most versatile camera Canon has ever produced (the 1D X II being the most versatile). Considering that the 5D Mark IV costs over 40% less than the 1D X II (USA MSRP), those compromises will seem very reasonable for a great number of pro, semi-pro, enthusiast and hobbyist photographers alike.

Advantages of the EOS Rebel T7i over the EOS Rebel SL2:
 

• More advanced AF: 45 cross-type AF points (27 f/8 points [9 cross-type], center point f/2.8 and f/5.6 dual cross-type) vs. 9 AF points (f/5.6 cross type at center, extra sensitivity at f/2.8)
• Wider AF working range (better in low light): EV -3 - 18 vs. EV -0.5 -1
• Better metering: 7560-pixel RGB+IR metering sensor, metering with the area divided into 63 segments (9 × 7) vs. 63 zone dual-layer metering sensor
• More autoexposure bracketing (AEB) options: 2, 3, 5 or 7 Shots +/-3 EV vs. 3 shots +/- 2 EV
• Intelligent viewfinder vs. fixed
• Single axis electronic level vs. N/A
• More powerful pop-up flash: 13.1 GN vs. 9.8
• Pop-up flash can act as master vs. N/A
• Faster continuous shooting and larger buffer: 6 fps, 27 RAW vs. 5 fps, 6 RAW
• Longer battery life: 820 shots vs. 650

Advantages of the EOS Rebel SL2 over the EOS Rebel T7i
 

• Higher viewfinder magnification: 0.87x vs. 0.82x
• Smaller size/weight: 4.82 x 3.65 x 2.75" (122.4 x 92.6 x 69.8mm), 15.98 oz (453g) vs. 5.16 x 3.93 x 3.00" (131.0 x 99.9 x 76.2mm), 18.77 oz (532g)
• Lower cost

Who should opt for the Canon EOS Rebel T7i / 800D?
 
If minimal size/weight are not top priorities, and the Rebel T7i's higher price tag is not a barrier to investment, the T7i's higher-end features will make it a more versatile choice for most photographers. In fact, its more advanced, more sensitive in low light AF system alone is likely worth the T7i's price over the SL2.
 
Who should opt for the Canon EOS Rebel SL2 / 200D?
 
If you want the most lightweight, compact DSLR, or if your budget does not extend to the Rebel T7i's price tag, the Rebel SL2 will be a solid investment. The SL2 provides a solid feature set at a very reasonable price, and anyone carrying their camera kit for long periods of time (those hiking, for example) will surely appreciate the camera's smaller size and weight. Other groups who will gravitate to the SL2 include those with smaller hands and those intending to use the camera in a high-risk remote setup. Because of its small size and simple user interface, the SL2 may be the perfect DSLR to buy for a young photographer-in-training.
 
Summary
 
Built around an identical sensor and sharing many noteworthy features, the Rebel T7i and SL2 are more similar than they are different. Both deliver very good image quality, feature excellent subject tracking in video mode and offer an intuitive user interface that makes the cameras very easy to use, especially for those with minimal photography experience or otherwise transitioning from a compact camera or a smartphone.
 
Arguably the Rebel T7i's biggest drawback – its higher price tag – results from the inlcusion of noteworthy features not found in the SL2 (primarily, a much better AF system). For most photographers, the Rebel T7i will fulfill their needs better because of those additional features. But for those who don't need those features, are budget limited or who otherwise value reduced size and weight, the Rebel SL2 remains a viable option.
