Thanks! Share it with your friends!


Win a Canon EOS R at
We review the Sony a7 III ( vs the Canon EOS R ( We discuss the design differences, the controls (buttons, dials), card slots (1 vs 2), battery life (and USB charging), native lenses, adapted Canon EF lenses, image quality (including dynamic range and banding), lens and sensor image stabilization, autofocus for stills and video, EYE AF, silent shooting, frames per second, and video quality. Finally I recommend one camera over the other for casual shooters, sports shooters, photographers who own lots of Canon lenses, wedding photographers, vloggers, and videographers.

Iki’s Photography says:

Didn’t know you were a vlogger Tony

Edwin Lee says:

What is that 2 little circular tag at the sides of canon eos r?

Sathyameva Jayathe says:

Canon R the best.

M30 Tech says:

Great video. but that mannequin head, lol.

Dave McIntosh says:

All the people busting on the EOS R – simply try it. I was a Nikon shooter who wants a camera that can also do video. I purchased the Sony A7RIII when it came out and it felt like a small metal brick in my hand and not balanced with their lenses. I was accidentally hitting buttons and it didn't reliably focus for me in low light so I sold the entire Sony kit. I too was a Canon EOS R naysayer based on specs but the Canon lineup of R lenses intrigued me )vs the Nikon lenses which seemed to be lower end. If I am buying into a system I want great lenses and Canon is bringing great R lenses to market. I tried the EOS R and I liked how it fit in my hands and it focuses wonderfully and takes great photos. It is perfect – No – but it is really good and I like it better than the Sony A7 cameras I have owned. I should note I am a portrait and wedding shooter who also does video but I mostly use it for stills.  

Imagine If we reviewed cars the way we review cameras based on features and specs. Everyone would recommend a Hyundai because it has lots features and its cheaper.

Can't have an honest review if you get paid folks! You should be not reviewing and just selling:)

MDYT says:

Cliff notes: If you are any sort of professional get the Sony. After 15 years with Canon (1DS, 5d II, III, IV) the EOS R is a tone deaf release and shows me where Canon's road map will take them. I got off at the A7III exit.

Daddy Tech says:

yeah that Canon is not worth the extra $1,000+ price tag..

Michael Sawyer says:

All of the reviews of both the a7iii and the R had convinced me that the a7iii was my next camera. However, I went to the local shop and actually held/shot each for a couple hours and I am back on the fence.

The a7iii was very uncomfortable compared to the R, hard edges. (i.e. small for my hands, hard edges, buttons that feel soft, etc)
The a7iii space between the grip and lens (due to the smaller mount flare), was almost painful with the Zeiss lens'.
The a7iii discomfort was the first and persistent factor that keeps me looking at the R.
The AF was a little confusing on the R compared to my past Canon DSLRs. (However, I have seen demos like this one that shows I just didn't know how to leverage it.)
The Canon touch screen is amazing, but it would take some muscle memory training to adjust to the M-Fn slider. (I was beginning to like it when I left)
The Canon EVF is noticeably higher resolution and easier on your eye.
The a7iii Video features far out-weigh the R, but the video isn't a huge focus for me.
The R FPS is ridiculously slow on the spec sheet, but it didn't seem slow in my hand. Not sure, I'll have to test it shooting my dog and kids running to determine it.
The a7iii EyeAF was amazing, the R worked well but definitely not as quick as the a7iii.

For me, the answer will be to rent both independently for at least a couple of days and make my decision based on my experience. The specs are similar enough for what I care about, that it will come down to how they perform after I have learned a little more muscle memory. Either way, by the end of 2019 I will be purchasing one or the other. I love the competition from Sony, if it weren't for that, I would have just purchased the R. Now I have two awesome mirrorless options to choose from and have better options for my preferences.

Howard Kahn says:

you should have used Sigma's 24-105mm f4 lens, it blows away sony and canon's version…….and it is much cheaper…….

Steve Colby-Doll says:

Die-hard Canon guy here, mainly video. Poop. I might have to switch to Sony. Not too happy about it. I have quite a few Canon lenses. Urg…

Rushil Ambani says:

Hello . Excellent review . I am planning to upgrade to full frame . Don’t own full frame lenses . My main areas are landscape and portraits . I shoot only stills and no video . What do you recomend . A7iii + tamron 28-75 + get wide lens for astro
Eosr with 24-105
Is ergonomics of canon worth the relatively inferior sensor and lack of ibis. ( actually where i live there are neither of both available at display on stores)
Thanks in advance.

spankwalla says:

DPReview compared the Nikon Z6, Sony A7 III and Canon EOS R, and Sony beat Canon in every category if I remember correctly, and the Canon came 3rd an alarming amount of times.

Ravencroft says:

EOS R "one of the worst sports cameras I have ever used" Sports Illustrated Peter Read Miller takes the R to the NFL with a 400mm on it. LOL

Frank phadika promotions says:

It doesn’t Metter which camera as long as u know what u want u can still get the best out of both.the man behind the camera is the most important than the the only master s touch that changes everything.

James D. Buzzard says:

Tony has the worst luck with sd cards. Award for most failed sd card goes to this channel hands down. Just curious but what brand and type of card failed? We need a chart of most failed so we know what has the most issues. I have never had a failure but will be pissed the day I do.

Lex Ells says:

Oh man I didn't know the Eos R didn't have in-body stabilization. That's a big hit against it

Nick Twaddell says:

I think I might be sold on the a7 III


the very first time i used a sony i hated it just because of the screen. i was using that on a Ronin M and it was no easy task and apart from not being able to see the screen without doing reps like i'm at the gym, i couldn't tell what was in focus majority of the time even with focus peaking on…its like a "Yay" situation when they announce the specs of the cameras but there always "o man" situation with them also. Do they hate flip screens or something.

Maximiliano Troncoso says:

I am a canon boy but i'm very disappointed since canon mark III, how canon 6D have wifi and mark III doesn't? the dinamic range is way behind the others brands, and it's soooo expensive cameras but doesn't have an equivalent with the others brands, nikon and sony are impresive cameras when you compare in the same conditions.

ps: sorry the grammar i'm not speak english very well.

Ning Zhao says:

Isn't that A7R3 on the desktop?

Keith Douglas says:

good job, lose the commercials

Chris Bailey says:

What Sony camera are you actually reviewing, Tony? The tittle says A7III but the Sony camera you are showing clearly has an R on it? Are you comparing the Sony A7RIII?

MrRyanwalsh11 says:

A7R3, clear winner

Keo Encinas says:

I get you don't want to be disliked by Canon as a company and want to stay unbiased being such a massive channel that this is, but please don't pretend such a blatant better camera is equal to something new and "hot", it doesn't look good in the eyes of viewers 🙁 The only real bad part is the beginning statement, I'm assuming it was to protect the canon fan base?

Chenwei Ku says:

Great review! Thank you. I am trying to decide between the two for taking mostly photos and a little bit of video. It is all in outdoor settings of nature with wildlife that is fast moving and often in low lighting such as sunset or night time. I need quick focus because of the fast moving wildlife. I love the colors of the canon, but from your review the Sony a7III sounds better. I am also looking for one where I can get focus as best as possible on both the wildlife up close with landscapes in the background such as mountain ranges. Which camera would you recommend for this kind of use? Thanks for your review.
