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.
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.
On November 1, 2018, we announced how we’d begin
bringing Flickr back to its roots: an active, photo-sharing community.
This meant upgrading our Pro accounts and changing Free accounts to encourage photographers to use Flickr again for interaction and inspiration and not just for backup storage.
A big part of that inspiration comes from those of you who have shared your photography with Creative Commons licensing.
And from historical, governmental, and nonprofit organizations that have shared amazing photos via The Flickr Commons.
Those photos, and your ability to share them, are important to us.
That hasn’t changed.
Those photos aren’t going anywhere.
To understand what does change, though, we first need to understand what The Flickr Commons
and Creative Commons
The Commons Difference
The Flickr Commons is for photos that come from institutions that want to share their digital collections with as many people around the world as they can.
These tend to be historical images whose copyright has expired or government images that are automatically in the public domain since taxpayers have technically already paid for them.
Photos from NASA
, The Smithsonian
, The National Archives UK
, and The British Library
, for example, have been shared in The Flickr Commons.
As part of The Flickr Commons, all these organizations already were Pro or have received a free Pro account from us, so they have unlimited storage.
The Creative Commons (CC) organization
has developed a suite of licenses that give individual photographers or groups great tools for licensing their photography for others to freely use.
The photographer keeps their copyright and gives the public an easy way to use their images as long as the license terms are followed.
The Flickr Commons and Creative Commons are different, thus our storage changes affect each differently (or not at all).
Are Commons Photos Being Deleted?
And once more for good measure: no, Commons photos are not being deleted.
The Flickr Commons photos (those uploaded by the archival, governmental, etc.
institutions we are working with) are safe.
We are extremely proud of these partnerships.
These photos won’t be deleted as a result of any of our announced changes.
The only reason they’d disappear is if the organization that uploaded them decided to delete them.
Photos that were Creative Commons licensed before our announcement are also safe.
We won’t be deleting anything that was uploaded with a CC license before November 1, 2018.
Even if you had more than 1,000 photos or videos with a CC license.
However, if you do have more than 1,000 photos or videos uploaded, you’ll be unable to upload additional photos after January 8, 2019, unless you upgrade to a Pro account.
Flickr Commons photos will not be deleted.
Anything uploaded with a CC license before November 1, 2018, won’t be deleted, but users will need to upgrade to Pro to upload more than 1,000 photos or videos.
What About Non-Profits?
We know and understand that there are groups out there that work hard to scrape together every nickel and dime to run their organization.
And we want to help remove any stress that may come from finding a place to host photos.
We’ve worked with 501(c)(3) charitable organizations for years at SmugMug to provide them with unlimited, free storage, and we’ll be doing the same at Flickr.
Organizations such as the United Nations Children’s Fund (UNICEF
, and Second Harvest
are already using Flickr to share photos of the amazing work they do.
And now we’ll be working with them to ensure Pro isn’t a cost they need to worry about.
In fact, you can fill out the form from this page
with information about your 501(c)(3) organization or international charity, and we’ll work with you to get your free Pro account set up.
The Future of the Commons
Freely licensed photos are deeply important to us.
After SmugMug acquired Flickr, one of the first meetings we had was with Ryan Merkley, the CEO of Creative Commons.
We want to keep that partnership alive and strong, and we are actively working on how to grow it for the future.
“We’ll be working with Flickr to look for ways to continue growing and archiving the commons,” Merkley said.
“When Flickr users apply CC licenses to their works, they are inviting everyone to use their works freely and with very few restrictions.
That’s an incredible gift to the world, and that generosity should be acknowledged and preserved into perpetuity for everyone to enjoy.”
Whatever changes come in the years going forward, the importance of these photos will always matter to us.
We not only want to preserve the photos we have, we want to keep partnering with organizations such as libraries, museums, and government agencies to contribute to The Flickr Commons as well.
And we will continue to work hard to keep these photos safe and available for the world to view and enjoy.
