by Roger CicalaSee the LensRentals Canon EOS R Teardown for more information.I’ve wanted to look inside the new Canon and Nikon mirrorless cameras since the moment they were announced, so I’m probably more excited about this than you guys are. I’m really not sure what to expect. Early on, when we took apart a Sony A7R, we were struck by how clean and straightforward mirrorless cameras were compared to DSLRs. Later, we took apart an A7RIII and found that increased capabilities led to increased complexity, although still not as complex inside as a DSLR.
So we expected things not to be too complicated – no mirror box, optical prisms, off-sensor AF system, etc. We know Canon cameras to have clean, even elegant, engineering; like the 5D IV teardown shows. We haven’t done a Nikon SLR teardown in quite a while (the D7000 was the last one), but their camera engineering is pretty similar to Canon’s, although being Nikon they still like to leave some soldered-wire connections here and there. So we figured that the new Canon and Nikon mirrorless full-frame cameras would be more straightforward than their SLR cameras, and perhaps Nikon set down the soldering gun and slowly stepped away.
But really we had no idea how things would look inside, if we might see some cool new engineering, what the weather resistance would be like, etc. So we took apart both a Canon EOS-R and a Nikon Z7 just to have a look around. (The Z will get written up as soon as I can get to it.)
LensRentals has the Canon EOS R and Nikon Z 7 available for rent.
From Tokina:
Thank you for using Tokina products.
We have thoroughly tested all current Tokina interchangeable lenses (Nikon F mount) with the Nikon Z 7 mirrorless camera using the Nikon mount adapter FTZ.
The results confirm that current Tokina lens models showed no issues in general operations with the following exceptions:
Please, note that due to mount adapter FTZ specifications, the following Tokina lenses do not AF but will operate in manual focus mode:

A general purpose lens is the most important and most-used lens in most photographers' kits. With a highly useful focal length range and a wide to moderately wide aperture, 24-70mm lenses can cover everyday needs, portraits, landscapes, cityscapes, food/travel and much more. Sony has two high-performing, 24-70mm constant max aperture zooms in its lineup – the FE 24-70mm f/2.8 GM and FE 24-70mm f/4 ZA OSS – and we're going to take a closer look at them to see which may be better suited to fill your general purpose needs.
Sony FE 24-70mm f/2.8 GM and Sony FE 24-70mm f/4 ZA OSS Shared Primary Features
Primary Advantages of the Sony FE 24-70mm f/2.8 GM Lens
Primary Advantages of the Sony FE 24-70mm f/4 ZA OSS Lens
Other Differences: Sony FE 24-70mm f/2.8 GM vs. Sony FE 24-70mm f/4 ZA OSS
Image Quality Differences: Sony FE 24-70mm f/2.8 GM vs. Sony FE 24-70mm f/4 ZA OSS
From a sharpness perspective, the "sharpest lens" title will depend on the specific aperture/focal length being compared. There isn't really a clear winner when the entire range of tests is taken into consideration. The FE 24-70mm f/2.8 GM shows slightly less vignetting at 24 & 70mm (vignetting is similar at the middle focal lengths) when the lenses are compared at their widest apertures.
When compared at f/4, the f/2.8 lens shows significantly less vignetting. The f/2.8 lens has less severe distortion over the zoom range (the difference is most noticeable at the lenses' widest and longest focal lengths), but most will prefer the f/4 lens' flare performance.
Who should opt for the Sony FE 24-70mm f/2.8 GM?
There are many drawbacks to an f/2.8 constant max aperture lens compared to an f/4 constant max aperture lens, including increased size, weight and cost. However, the Sony FE 24-70mm f/2.8 GM's twice-as-wide max aperture will allow you to freeze motion in half as much light at the same ISO setting compared to the FE 24-70mm f/4 ZA OSS. If you're a wedding/event photographer, or prefer not to pack a tripod for nighttime cityscape/street photography adventures, the increased size/weight/cost associated with the f/2.8 lens will prove more than worthwhile. Portrait photographers will also appreciate the better subject-to-background separation provided by the 1-stop wider aperture and the smoother bokeh/better starbursts created by its 9 bladed aperture (vs. 7).
Who should opt for the Sony FE 24-70mm f/4 ZA OSS?
If you don't often need to capture moving subjects in low-light situations, and can tolerate higher ISO use when the need arises, then the Sony FE 24-70mm f/4 ZA OSS offers many of the benefits of the Sony FE 24-70mm f/2.8 GM at less than half the price. For static subjects, when combined with Sony alpha-series cameras' IBIS (In-Body Image Stabilization), the Sony FE 24-70mm f/4 ZA's Optical SteadyShot should provide even more effective stabilization compared to a lens without built-in IS.
As you can see by the product pictures and specs listed above, the size and weight differences between these two lenses are substantial. Photographers who will benefit from the FE 24-70mm f/4 ZA OSS's smaller size/lighter weight include anyone carrying their gear for long periods of time (for backpacking, vacations, long events, etc.) and those wanting to pack more gear in a similar amount of space.
Summary
With many full frame Sony a-series cameras having built-in sensor stabilization, one of the Sony FE 24-70mm f/4 ZA OSS Lens's major benefits – optical stabilization – is diminished. However, it does have a few advantages remaining over the Sony FE 24-70mm f/2.8 GM that aid in boosting the f/4 lens' popularity – smaller size, lighter weight and a much lower cost. If any of those features is a priority for you, then the Sony FE 24-70mm f/4 ZA OSS is the lens to get. Otherwise, a 24-70mm f/2.8 zoom has been a must-have lens for a wide variety of professional photographers over the years, and for those choosing Sony gear, the FE 24-70mm f/2.8 GM is one of the first lenses they'll be adding to their kits.

I've been shooting a moderate amount of indoor studio portraits over the last couple of years and I am consistently impressed by the impact a fan has on the quality of my images. Take the shot above, for example. In it, I'm using six flashes to illuminate the subject and background (with various modifiers). Good lighting is a key to producing a high quality studio portrait. But the finishing touch, the element that makes this photo really interesting, is the hair movement provided by the fan placed just in front of the subject.
In this case, the fan is a oscillating, variable height/variable speed pedestal model that my dad gave me when he was moving [downsizing] a few years ago. He used it to minimize his home cooling expenses; I use it to get shots like this:
Of course, for a fan to have an impact on portraiture, it must influence at least a part of the composed scene in some way. You can use the fan to introduce movement in hair, fabric/clothing or props (such as leaves). The opportunities for capturing dynamic, fan-induced movement in your portraits are too numerous to list.
If shopping for a fan for studio use, from my personal experience, a pedestal model with an adjustable height is ideal as you can easily set it to an optimal height for your subject. However, a pedestal-style fan certainly isn't a requirement. If you already have a floor model or tabletop fan, you can simply place it on a higher surface (table, apple boxes, etc.) if needed. While some may appreciate an oscillating feature (especially if the fan is doing double duty as a cooling device), I typically lock my fan into a static position so that it's always blowing air in the desired direction.
Note that constantly blowing air at a subject's face can cause uncomfortable dry eyes. To prevent this, tell your subject to keep his/her eyes closed right up until the moment a photo is taken and use an audible countdown to alert the subject of an impending shutter release.
A fan is an inexpensive tool that can have a big impact on the quality of images delivered to your clients, making it a must-have item for any studio photographer.
It has been raining and mostly cloudy here on the USA east coast practically all summer. The funny saying goes something like this: "It rained twice here this summer, once for 6 weeks and once for 7 weeks." Those dark weather conditions greatly challenge outdoor camera and lens testing as any clouds in the sky can mean unequal shot-to-shot lighting.
At the other end of the spectrum is Colorado, currently experiencing an extreme drought with reservoirs at historic lows (Crater Lake in the Maroons Bells Scenic Area was empty). So, it would make sense that clear skies could be found there.
Amazingly, the day I flew out to Colorado, it was clear here and I arrived to heavy clouds, rain and snow that lasted practically my entire time there (note: I'm available to hire for rain-making). Thankfully, the night before I left was clear and I was able to do some night sky camera and lens testing.
Focusing on stars at night is always a challenge and the Canon EOS R's EVF proved up to that task. I have been very impressed by the R's low light AF capabilities, especially with the Canon RF 50mm f/1.2L USM Lens mounted and when that lens took its night sky turn, I decided to try autofocusing on a bright star. Under my local modestly-dark sky (this light pollution map shows this location as between yellow and green and some town glow is seen in the bottom of the included image), the EOS R with the center AF point selected successfully and repeatedly autofocused on bright stars. This task does not get easier.
Before you ask me about specific EOS R and lens combinations being able to do this, know that I returned back east to heavily clouded skies and it has been raining heavily all morning.
The Canon EOS R is in stock at B&H | Amazon | Adorama | WEX.
