The Canon EOS R and Sony a7 III fill an fascinating position. Neither digicam is the latest or most spectacular, however they nonetheless supply a set {of professional} capabilities at a cheaper price than their top-of-the-line versos. They’re each wonderful choices for fanatics outgrowing lower-tier cameras or for semi-pros who can’t but justify the price of the flagships. Additionally they supply an awesome place to begin for somebody stepping into (or changing to) both the Sony or Canon ecosystems.
With each cameras being about 3 years previous and coming down in worth, it’s a superb time to have a look at how they evaluate and see if one can be a sensible choice for you.
Canon EOS R vs. Sony a7 III Specs
Launched in 2018, Canon’s EOS R and Sony’s a7 III have largely shared the identical house and focused the identical consumers, although the 2 cameras adopted pretty totally different paths to return into being.
The EOS R, Canon’s first foray into the complete body DSLR-style mirrorless format, was largely seen as simply the 5D Mark IV stuffed right into a mirrorless physique. With the 5D Mark IV being a strong DSLR that was strongly aligned with the wants {of professional} shooters, the EOS R got here full of a robust set of professional-grade options, although they have been now not strictly “leading edge.”
The Sony a7 III, however, was the latest addition to Sony’s already spectacular and well-known mirrorless lineup. Sony’s strategy for his or her full body Alphas has been to constantly fill out their function units with probably the most thrilling, cutting-edge choices obtainable. The a7 III particularly was designed to be their “price range” providing (now that position belongs to the Sony a7C), benefitting from a number of options trickling down from extra highly effective fashions, providing big capabilities for the worth (however not essentially specializing in anyone function). In different phrases, it provided the perfect it might for the widest number of capturing conditions.
Regardless of their variations in lineage, each cameras ended up becoming a really comparable area of interest: full body mirrorless our bodies launched at round (usually below) $2,000 that provided all of the capabilities that the majority shooters might ever need, even when they didn’t essentially embody probably the most superior specs.

Canon EOS R vs. Sony a7 III Options
Wanting on the chart above, there are positively specs that favor every digicam. However let’s dig just a little deeper into their options to see if one digicam may finest suit your wants.
Sensor Decision
Whereas sensor decision is actually not the be-all-end-all issue, it’s a superb place to begin for a comparability.
Each cameras are in a relative candy spot, providing sufficient decision for all however probably the most excessive makes use of whereas not packing in so many pixels that storage and processing calls for begin to take a significant hit. Canon’s 30.3 megapixel sensor offers you extra cropping functionality than Sony’s 24.2 megapixel, however for many shooters both might be greater than sufficient. A better approach to consider it’s the EOS R will produce 6720 x 4480 pixel pictures, whereas the Sony a7 III will produce 6000 x 4000 pixel pictures. Seen like this, the distinction feels much less vital. Each produce UHD 4K at 3840 x 2160.
Autofocus
One of many advantages of evaluating cameras a number of years after launch is that updates generally change the comparability. Whereas the EOS R continues to make use of the much-lauded Twin Pixel AF that has been featured in a lot of Canon’s DSLRs, Sony’s Eye AF set it aside at launch. In late 2018 or 2019, the a7 III was the clear winner. Nevertheless, Canon launched its personal model of Eye AF with the EOS RP, a system that was capable of be added to the EOS R by way of firmware updates.
Primarily based on real-world opinions, Sony appears to edge out Canon by way of uncooked velocity for attaining focus, although Canon appears to edge out Sony in total accuracy. This means that precise outcomes are pretty equal between the 2 cameras.
In fact, how properly your autofocus will work doesn’t solely rely in your digicam physique. Totally different lenses, lighting situations, distance to topic, and different components can push one digicam forward of the opposite. Backside line, although, is that neither digicam is prone to make you want you had the opposite on this space.
Low Gentle Efficiency
The Canon EOS R has robust low gentle efficiency, however for those who anticipate to be incessantly capturing in low gentle situations, the Sony a7 III positively outpaces the Canon.
A part of Sony’s benefit comes from the truth that it does have the decrease decision sensor. It’s not an enormous profit, however all else being equal, fewer pixels in the identical space will result in higher gentle sensitivity. Even with out this issue, although, the dynamic vary and low gentle sensitivities of Sony’s sensors have been higher than Canon’s for some time (although Canon is enhancing its strategy with the R5 and R6.)
If you wish to be absolutely ready for difficult lighting situations, the a7 III might be the higher possibility.
Picture Stabilization
One other space the place Sony strikes forward of Canon is in picture stabilization. With the Canon EOS R, you’re restricted to in-lens picture stabilization. Whereas some lenses (notably a few of Canon’s new RF lenses) have extremely spectacular IS, Sony’s in-body picture stabilization is highly effective and presents stabilization it doesn’t matter what lens you placed on the digicam.
For a lot of customers, the shortage of IBIS within the EOS R might be a deal-breaker.
Video Capabilities
Whereas Canon was the primary to supply professional-grade video functionality in a DSLR physique (approach again with the 5D Mark II), mirrorless cameras have considerably pushed the capabilities of their our bodies to be hybrid nonetheless/video cameras.
Although each the EOS R and the a7 III can seize spectacular footage, if you’re wanting highly effective video capabilities, the a7 III is unquestionably the stronger digicam.
Maybe probably the most mentioned benefit of the a7 III is the crop issue when capturing 4K footage. Many hybrid shooters are drawn to full body mirrorless cameras due to the advantages in subject of view and depth of subject {that a} full body sensor presents. Nevertheless, the EOS R has a big 1.74x crop issue, eliminating all of these advantages. The a7 III, however, can shoot uncropped 4K when capturing at 24 frames per second, or a a lot smaller 1.2x crop when capturing at 30 frames per second.
Talking of body charges, whereas each cameras max out their 4K recording at 30p, for those who’re prepared to go right down to Full HD, the a7 III will shoot as much as 120p in comparison with the EOS R’s 60p. With the EOS R it’s a must to go all the way in which down to simply HD to get comparable sluggish movement advantages.
One other main energy of the Sony is its aforementioned IBIS system, which is invaluable when capturing easy, stabilized footage. There are some workarounds with the EOS R, however the a7 III goes to be a way more pleasant expertise if you’re capturing handheld video.
Lastly, the Sony presents extra options concentrating on videographers, comparable to zebras and focus peaking, that are lacking totally on the EOS R.
Battery Life
One other space the place the Sony a7 III edges out the Canon EOS R is in battery life. Whereas your precise battery life will rely upon what and the way you’re capturing, Canon claims a battery lifetime of round 370 pictures whereas Sony claims simply over 600. For those who routinely shoot a excessive variety of pictures at a time, the less instances it’s a must to change your battery, the higher.
Ergonomics
Ergonomics is tough to match as a result of each particular person can have their very own desire, usually primarily based on what they’re used to. Nevertheless, if we needed to name a bonus to 1 digicam over the opposite, the benefit would probably go to the Canon EOS R – with caveats that, sorry to say, will in all probability not make it any simpler so that you can make a decision.
Whereas the a7 III is barely smaller, the burden of the 2 cameras is nearly similar. For many individuals, the marginally bigger physique, and particularly the deeper grip, of the EOS R will probably match their hand just a little higher (although, once more, this can be a private desire).
Apart from the bodily ergonomics of the 2 our bodies, one space of usability that’s broadly considered being higher with Canon cameras in comparison with Sony is the menu construction and accessing the totally different settings and software program options of the digicam. Sony has lengthy been criticized on this entrance – their menus and settings setups are thought-about complicated, busy and buried.
One other ergonomic factor is the D-pad vs joystick management on the again. Sony is advantaged right here with a pleasant, tactile joystick.
Viewscreens
As with different mirrorless cameras, each the EOS R and the a7 III have twin digital screens for viewing when capturing: the rear LCD and the Digital Viewfinder (EVF). Which one you employ when capturing comes down to non-public desire, however Canon gives a greater expertise when utilizing both.
For the EVF, the most important benefit comes from the upper 3.69 million dot decision. Regardless of having barely extra magnification (0.78x vs. Canon’s 0.76x), Sony’s 2.36 million dot EVF is, frankly, considerably underwhelming.
For the again LCD, Canon’s isn’t solely barely bigger (3.15” vs. 3”), it additionally has a considerably larger decision (2.1M dots vs. 922K dots). Moreover, the EOS R brings Canon’s absolutely articulating design that makes it a breeze to view from nearly any angle, a function that’s much more pleasant than the tilting design of the Sony’s rear LCD.
Burst Capturing
Sports activities and wildlife photographers largely dwell by their digicam’s burst capturing mode, and the a7 III wins right here. Whereas its 10 FPS bursts don’t look a lot totally different than Canon’s 8 FPS bursts on paper, in the actual world that’s 25% extra pictures captured, which might find yourself being make-or-break in extraordinarily quick capturing environments.
Reminiscence Playing cards
Each cameras use UHS-II SD playing cards, however the EOS R is proscribed to 1 card slot whereas the a7 III presents two. Whereas having a second slot isn’t completely crucial, it’s a good perk – verging on a necessity – for a lot of shooters. I actually wouldn’t really feel snug capturing on just one card, so the Sony wins out on this regard.
A second reminiscence card slot provides you a few totally different choices relying in your capturing workflow. If you’re capturing a really excessive quantity of pictures or a whole lot of lengthy movies, the second reminiscence card might be a useful overflow possibility, permitting you to seamlessly begin recording your recordsdata onto the second card with out having to change and doubtlessly miss pictures throughout that point. Alternatively, if you’re capturing footage that’s important and irreplaceable, the second card slot can be utilized as an prompt backup, recording the pictures to each playing cards and making certain {that a} reminiscence card failure received’t end in dropping necessary work.
Lens Mount and Ecosystem
On the finish of the day, maybe the most important consideration when selecting between the EOS R and the a7 III is which ecosystem you need to be a part of. Lenses will lengthy outlast any digicam physique you employ, and few folks can justify incessantly rebuying equal lenses in numerous mounts as a result of they need a distinct digicam physique.
Luckily, each cameras have a strong ecosystem and lens choice, which means that neither will maintain you again.
At launch, the EOS R’s RF mount solely had a number of choices obtainable. Their choice has expanded significantly over the past three years, however there are nonetheless fewer RF lenses at the moment obtainable than Sony’s E mount lenses, particularly when you begin taking a look at third social gathering producers.
Nevertheless, Canon took the step of providing three improbable EF to RF mount adapters that can help you use EF or EF-S lenses with no lack of efficiency (some reviews even say that some EF lenses work higher tailored to the RF mount than they did natively on older cameras). These adapters additionally supply some intriguing options, comparable to the additional management ring that’s on some RF lenses or a rear drop-in filter. With entry to EF and EF-S lenses, you get an unlimited vary of lens picks.
In fact, Sony’s E mount lineup is improbable as properly, notably its G Grasp collection. For those who’re transferring as much as both the EOS R or the a7 III, your present gear might be an extremely compelling motive to remain inside your present ecosystem, doubtlessly even outweighing any of the concerns above. For those who’ve already invested in some Canon gear, the swap to the EOS R might be a lot simpler, financially talking, than to the Sony a7 III, even when contemplating Canon’s new mount kind.
Conclusion
The Canon EOS R and the Sony a7 III are each extremely highly effective, providing a set {of professional} options at a aggressive worth level. For those who’re taking a look at transferring into both the Canon or Sony ecosystems or taking a look at upgrading from a extra entry-level physique to one thing that might be used professionally, they’re each improbable choices.
Every digicam has its distinctive strengths and benefits over the opposite. For many individuals, the a7 III will probably edge out the EOS R because of options like IBIS, a extra sturdy set of video options, higher low gentle efficiency, higher battery life, and sooner total frames-per-second capturing velocity. For others, the ergonomics, higher screens, and better megapixel rely on the Canon EOS R is likely to be the deciding components. Plus, the EOS R collection glass is thrilling and (comparatively) new. For me, the twin SD card slots, battery life, and ISO efficiency of the a7 III win out.
Both approach, you’ll get a digicam that can can help you accomplish what you need. Each are excessive sufficient decision for portraits and landscapes, quick sufficient for sports activities, and file in 4K. For those who’re nonetheless undecided between the 2, why not attempt them out and see which is a greater match? No overview/evaluate on this planet can evaluate to truly having hands-on expertise with the product.
