We review the Sony a7 III (http://sdp.io/a73) vs the Canon EOS R (http://sdp.io/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.

  1. After returning to photography after a 15 year break I was blessed to try out both these cameras before deciding. The reviews I Read and watched all favoured the Sony, but I came to the conclusion that like other electronics most reviews and comments focused on raw the technology not the art. In my opinion, the Sony was simply a joyless to use, confusing menus, shocking ergonomics and a really awful reputation for after sales service should anything go wrong. The better performance by the Sony at the margins was not enough to negate these issues as the Canon R provided vastly superior user experience in the field.
    I eventually went with the canon R. Was it the best technically? Probably not, but it’s ergonomics were superb, it’s wireless and Bluetooth made backups instantaneous, no need for another card, menus and ease of use were intuitive, the lens range was extensive ( even the couple of 15 y.o. Lenses I own worked) and I picked up a couple of second hand ones really cheap. Finally it was a joy to hold and use, like an old friend.

    I would venture to say that it will outsell the A7iii due to Canon’s reputation and ecosystems, and they know their market better than the bloggers on YouTube who often are ‘influencers’ who say what they are paid to say…and Sony are famous for this.

  2. Hi Sir, Iam wedding professional Photographer, I want ask a question ? Now I'm using Canon 5 D mark 3, now I'm going to mirroless camera , which one to choose, I'm in confusion plz suggest me. I have Canon lenses in my kit, need to change body only.

  3. Everyone is so ridiculous!
    The fact of the matter is that Canon is way ahead with Glass to choose from, but for whatever reason they are slow to getting professional mirrorless body out there that can actually compete with Sony.

    Canon WILL one day produce a great professional Mirrorless Camera, they are just going to play from behind. So, if you are a Canon guy with lots of glass, then do not jump ship. Stay the course and you will get what you want, you just have to wait longer.

    Sony is going to innovate and get you the latest tech faster (Canon has already admitted they are not interesting in innovating like Sony). Sony is lacking in Glass, but I believe they will slowly build that up to be a mood point. They have shown they are dedicated to being the top in the Professional Camera market . . . at least in Mirrorless, but that is the future! So, if you do not have a huge financial (or emotional 😛 ) investment in Canon, then I would go Sony. For now, you will have the lenses you need as a Sony man/woman, but you will have to wait a little while for more options. Those options will and are coming though.

    Overall, I am going with Sony as I am in a position to where going to Sony and ditching Canon will not ruin me financially, and I will have the lenses I need for now with what has come out for Sony. More options will come surely down the line. Eventually, I think Canon users will get to a point where arguing about glass is going to be a non-arguement because Sony will catch up while staying ahead in innovation.

  4. Let me know of you guys think my latest video has good b roll or what you think I could do better in my next video!! I have 2 cinematic sequences in there, first time I've ever done that so give me some feedback!! 🤟🏼🤟🏼

  5. To Tony Northrup: In your video here, of sample of 4K in 12800 iso (you walking back and forth) the Sony has much less detail than the Canon R and the Sony looks over smoothed on skin tones. Although, I realize that Sony used full frame for 4K, it is just that your example gives the win to Canon in this one test 4K at 12800 iso. Look at it a few times again and you will see I am right. So in other words, although Sony is a winner for full frame 4K and may have better dynamic range, the Canon still holds it own in 4K in low light by this test at 12800 iso as I think it holds more detail (maybe because of the 30MP sensor). I think Canon looks better here in this one example you show. Yes? or disagree.

  6. Sony 7iii record 4k 30 with crop the video
    And 4k 24 stretch up the video
    1080 120 slow motion without face dietician
    And use AA filter
    Can you confirm that please if it possible

  7. I am a long time Canon shooter who wont buy any new Canon gear until they come up with a camera that at least matches Sony's… Canon should at least offer the same spec as their best DSLR: higher FPS, thumbstick, 2 memory cards + IBIS…

  8. The flip screen was what makes my decision so hard when I finally decided to move to mirrorless system, as a 6d mark ii user I found it really comes handy with the flippy screen, but I finally decided to jump to ship to sony a7iii after 2 months of thought and never regret it!!!

  9. You didn't mention Canon's superior colour.
    If a selfie monitor is holding you back on the Sony, buy a hot shoe monitor and the price will be the same but a superior video… other than colour.

  10. I'm by no means an expert, but wouldn't something like the Panasonic GH5/GH5S be better as a vlogging camera than the Canon?

    The Canon seemed to have way more deal-breaking flaws than the Sony does. I also thought the circumstances under which the Sony exhibited banding made the shot look very unnatural anyway.

  11. why can't Canon offer 1080p 120 FPS at this price point? it's really driving me nuts. I'm not upgrading from my Canon80D until they release a full-frame at this price that can shoot 120fps.

  12. Except for the ergonomics, viewfinder, and control buttons, the Sony A7 lll is clearly superior, especially in low light. The comparison graph in DP Review shows the A7 lll is superior in most categories.

  13. SONY SEEMS TO BE SUPERIOR AND WAY AHEAD OF CANON. BUT YOUR PRESENTATION SEEMS TO COMPROMISE YOUR INTEGRITY. iF THE PERFORMANCE OF SONY IS THAT OF CANON, YOU GUYS WILL BLAST ALL OVER THEIR MODELS. BUT NONE OF YOU REVIEWERS HAVE GUTS TO STAND UP TO THE QUALITY. EVERYONE OF YOU WERE SHOOTING DOWN SONY 6400 FOR NOT HAVING IN BODY STABILIZATION. WHERE AS YOU ALL SEEM TO TOLERATE AND SAY IT IS NO BIG DEAL TO HAVE IMAGE STABILIZATION WITH EITHER CANON OR NIKON. IT IS APPALLING TO SEE THESE KIND OF BIASED REVIEWS AND YET PROJECT TO BE UNBIASED. SAD ! THE FLIP SCREEN MAY BE ONLY BIG DIFFERENCE WHERE CANON MIGHT BE USEFUL. THAT TOO HOW MANY PEOPLE ARE BLOGGERS WHO USE THESE FEATURE. YOU CANT BE EVERYTHING TO EVERYBODY.

  14. I like how canon puts IS in the lens. If there is a major innovation in IS, you won't get it on your Sony until you upgrade the body. The EOS R will have those new innovations because IS is in the lens.

  15. I'm almost always in agreement but the 17-40L and 135 work way better and focus faster on my a7iii then they do on my 5diii. Saying Canon lenses don't adapt well in a general statement is blatantly wrong.

  16. The comparision is very detail it is super ……….i am really happy in your explanation!!!!!!!!!!
    but i saw that the sony camera model in front of you is sony a7R not a7iii.i am right?

  17. for vlogging autofocus canon autofocus is better because its really quick but for professional autofocus sony is better because its really nice nice transition instead of digital looking autofocus
