Canon EOS R vs. Sony a7 III Comparison

The Canon EOS R and Sony a7 III fill an fascinating function. Neither digicam is the most recent or most spectacular, however they nonetheless provide a collection {of professional} capabilities at a lower cost than their top-of-the-line versos. They’re each glorious choices for fanatics outgrowing lower-tier cameras or for semi-pros who can’t but justify the price of the flagships. Additionally they provide a fantastic start line for somebody entering 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 very good time to have a look at how they examine 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 patrons, although the 2 cameras adopted pretty completely 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 robust DSLR that was strongly aligned with the wants {of professional} shooters, the EOS R got here full of a powerful set of professional-grade options, though they have been now not strictly “innovative.”

The Sony a7 III, alternatively, was the newest addition to Sony’s already spectacular and well-known mirrorless lineup. Sony’s method for his or her full body Alphas has been to repeatedly fill out their function units with probably the most thrilling, cutting-edge choices out there. The a7 III particularly was designed to be their “finances” providing (now that function belongs to the Sony a7C), benefitting from a number of options trickling down from extra highly effective fashions, providing large capabilities for the value (however not essentially specializing in anybody function). In different phrases, it provided the very best it might for the widest number of capturing conditions.

Regardless of their variations in lineage, each cameras ended up becoming a really related area of interest: full body mirrorless our bodies launched at round (typically below) $2,000 that provided all of the capabilities that almost all 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 slightly deeper into their options to see if one digicam may greatest suit your wants.

Sensor Decision

Whereas sensor decision is actually not the be-all-end-all issue, it’s a very good start line 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 serious hit. Canon’s 30.3 megapixel sensor gives you extra cropping functionality than Sony’s 24.2 megapixel, however for many shooters both can be greater than sufficient. A neater method to think about it’s the EOS R will produce 6720 x 4480 pixel photos, whereas the Sony a7 III will produce 6000 x 4000 pixel photos. Considered 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 couple 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. Nonetheless, Canon launched its personal model of Eye AF with the EOS RP, a system that was in a position to be added to the EOS R by way of firmware updates. 

Based mostly on real-world evaluations, Sony appears to edge out Canon by way of uncooked velocity for reaching focus, although Canon appears to edge out Sony in general accuracy. This means that precise outcomes are pretty equal between the 2 cameras. 

In fact, how nicely your autofocus will work doesn’t solely rely in your digicam physique. Completely different lenses, lighting circumstances, distance to topic, and different elements can push one digicam forward of the opposite. Backside line, although, is that neither digicam is more likely to make you would like you had the opposite on this space.

Low Gentle Efficiency

The Canon EOS R has robust low mild efficiency, however in the event you anticipate to be continuously capturing in low mild circumstances, 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 mild sensitivity. Even with out this issue, although, the dynamic vary and low mild sensitivities of Sony’s sensors have been higher than Canon’s for some time (although Canon is bettering its method with the R5 and R6.)

If you wish to be totally ready for difficult lighting circumstances, 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 might be 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 provides 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 can be a deal-breaker.

Video Capabilities

Whereas Canon was the primary to supply professional-grade video functionality in a DSLR physique (method 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, in case you are wanting highly effective video capabilities, the a7 III is certainly 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 discipline of view and depth of discipline {that a} full body sensor provides. Nonetheless, the EOS R has a big 1.74x crop issue, eliminating all of these advantages. The a7 III, alternatively, 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, in the event you’re keen 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 you must go all the way in which down to simply HD to get related gradual movement advantages.

One other main energy of the Sony is its aforementioned IBIS system, which is invaluable when capturing clean, stabilized footage. There are some workarounds with the EOS R, however the a7 III goes to be a way more fulfilling expertise if you’re capturing handheld video.

Lastly, the Sony provides extra options concentrating on videographers, akin to zebras and focus peaking, that are lacking solely 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 depend upon what and the way you’re capturing, Canon claims a battery lifetime of round 370 pictures whereas Sony claims simply over 600. In the event you routinely shoot a excessive variety of photos at a time, the less occasions you must change your battery, the higher.

Ergonomics

Ergonomics is difficult to check as a result of each individual can have their very own desire, typically primarily based on what they’re used to. Nonetheless, 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 decide.

Whereas the a7 III is barely smaller, the burden of the 2 cameras is sort of similar. For many individuals, the marginally bigger physique, and particularly the deeper grip, of the EOS R will probably match their hand slightly 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 extensively considered being higher with Canon cameras in comparison with Sony is the menu construction and accessing the completely different settings and software program options of the digicam. Sony has lengthy been criticized on this entrance – their menus and settings setups are thought of 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 private desire, however Canon supplies 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 will not be solely barely bigger (3.15” vs. 3”), it additionally has a considerably increased decision (2.1M dots vs. 922K dots). Moreover, the EOS R brings Canon’s totally articulating design that makes it a breeze to view from nearly any angle, a function that’s way more fulfilling 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 completely different than Canon’s 8 FPS bursts on paper, in the true world that’s 25% extra photos 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 provides two. Whereas having a second slot isn’t completely vital, it’s a good perk – verging on a necessity – for a lot of shooters. I actually wouldn’t really feel comfy capturing on just one card, so the Sony wins out on this regard.

A second memory card slot offers you a few completely different choices relying in your capturing workflow. If you’re capturing a really excessive quantity of photos or quite a lot of lengthy movies, the second reminiscence card could be a useful overflow possibility, permitting you to seamlessly begin recording your information onto the second card with out having to modify and doubtlessly miss pictures throughout that point. Alternatively, in case you are capturing footage that’s important and irreplaceable, the second card slot can be utilized as an prompt backup, recording the photographs to each playing cards and guaranteeing {that a} reminiscence card failure received’t lead to shedding 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 wish to be a part of. Lenses will lengthy outlast any digicam physique you employ, and few folks can justify continuously rebuying equal lenses in numerous mounts as a result of they need a distinct digicam physique.

Happily, each cameras have a sturdy ecosystem and lens choice, which means that neither will maintain you again.

At launch, the EOS R’s RF mount solely had a couple of choices out there. Their choice has expanded significantly over the past three years, however there are nonetheless fewer RF lenses presently out there than Sony’s E mount lenses, particularly when you begin taking a look at third social gathering producers.

Nonetheless, Canon took the step of providing three incredible EF to RF mount adapters that permit you to use EF or EF-S lenses with no lack of efficiency (some stories even say that some EF lenses work higher tailored to the RF mount than they did natively on older cameras). These adapters additionally provide some intriguing options, akin 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 infinite vary of lens choices.

In fact, Sony’s E mount lineup is incredible as nicely, notably its G Grasp sequence. In the event you’re shifting as much as both the EOS R or the a7 III, your present gear could be an extremely compelling cause to remain inside your present ecosystem, doubtlessly even outweighing any of the issues above. In the event you’ve already invested in some Canon gear, the swap to the EOS R can 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 collection {of professional} options at a aggressive worth level. In the event you’re taking a look at shifting 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 incredible 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 strong set of video options, higher low mild efficiency, higher battery life, and sooner general frames-per-second capturing velocity. For others, the ergonomics, higher screens, and better megapixel rely on the Canon EOS R could be the deciding elements. Plus, the EOS R sequence 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 method, you’ll get a digicam that may permit you to accomplish what you need. Each are excessive sufficient decision for portraits and landscapes, quick sufficient for sports activities, and document in 4K. In the event you’re nonetheless undecided between the 2, why not try them out and see which is a greater match? No overview/assessment on this planet can examine to truly having hands-on expertise with the product.
