From a quick Google search, I get the impression that there's not a large difference in specifications between the two cameras. Resolution is about it, but the Canon's resolution is still plenty. And frankly, I think you'd be better off asking Google than asking here; I find it unlikely that most people here have shot extensively with both cameras, especially given that this is a Sony subreddit. The biggest difference that I can see, right off the bat, is in the number of native lenses. While Canon is catching up, they don't have nearly as wide a range of both on-brand and third-party offerings yet - although that is a gap that will shrink in the future. I really think you're comparing two very similar things here, though, at least based on a quick perusal on Google. I think that it depends a lot more on lens availability, ergonomics, and what you think about each company. I got an a7 III recently, but that's largely because Canon doesn't have anything with the features I want in my available price range, and I already had some Sony lenses. Aside from that, the way that Canon crippled their cameras' video capabilities on launch makes me not trust the company for the time being. I saw tests where people attached an intervalometer to their camera while it was sitting in the freezer and taking one picture every minute, and the camera claimed it couldn't record video without overheating. Removing the "clock" battery from the motherboard also let you take video immediately after the camera said it detected that it was overheating, proving that it was just a built-in timer and not actually based on heat measurements. From what I've heard, Canon mostly fixed that through firmware updates after some major outcry, but that's why I'm personally a bit hesitant about the company for the time being. But you might not care about that, and I feel like most probably don't. Take a look at Google and decide for yourself. You won't find many people here who have even managed to get much use out of their a7 IVs, let alone comparing to the Canon R6. Answer from chicken_person on reddit.com

Sony α7 IV vs Canon EOS R6 Mark II: Which Camera Is Better? - RTINGS.com
February 8, 2021 - The Sony has a higher-resolution sensor, but the Canon performs a little better in low light. Both can handle advanced video work, with internal 10-bit 4k at up to 60 fps, though the Sony imposes a significant crop on 4k / 60 fps video.

I suppose you are here not for a re-iteration of the spec sheet but a more subjective “human” analysis I have been using the Canon system since the film EOS3 days and then moved on to the 300D and 1D. Canon was a very innovative company back then, for example the early 300D was the best camera under $1000 period, and Canon’s sensor performance was miles ahead of anyone else. In 2012 Canon released the 6D. While the Nikon D600 was arguably better, the 6D was close enough. This was the first “affordable” full frame camera made by Canon at the $2000 mark. Prior to this, a full frame camera like the 1Ds cost $8000. As I often used just the center AF point even on the 1D, the 6D really was good enough for the kind of photography I was doing then. Sometime after this, Canon stupidly decided to cut R&D spending… Fast forward to late 2017 and Canon was releasing very disappointing cameras. The 6Dii actually had worse dynamic range than the 6Di, and there was almost no reason to upgrade from the 6D. In fact, the 6Dii did not compare very favorably to the Nikon D750, which released in 2014! In 2017, the Sony A7ii was also unattractive. AF performance was frankly still terrible and it hunted all the time In early 2018 Sony released the A7iii and once I saw the eye AF I immediately knew it was an absolute game changer. The AF on the A7iii while not perfect, was incomparably better than the A7ii. The existence of the Sigma MC-11 meant that could adapt all my Canon glass, so I picked up an A7iii over the 6Dii or 5Div Fast forward to 2021 and Canon finally has decent cameras again, the big boon for the Canon system is that the Canon EF mount adapter is essentially perfect. Existing EF mount lenses will pretty much work perfectly Unfortunately as a “complete package” there are problems… note: I strongly dislike lenses which barrel-extend due to past experiences with water vapor ingress even with plastic lens protectors For super telephotos: The Sony 200-600/6.3 is more attractive (to me) than the barrel extending Canon 100-500/7.1, and the Sony 200-600 is much cheaper too. The Sony 70-200/2.8ii is much more attractive than the canon variant because it’s so light, similar in weight to an 70-200/4. The Tamron 150-500/5-6.7 may be a good cheaper alternative, but there’s no RF version yet AFAIK The Canon 800/11 is quite interesting, but given the pricing I still rather get the brighter Sony 200-600 Overall: Sony Wins due to the 200-600 For wide primes: The Canon 35/1.8 is only average optically but at least it’s cheap Meanwhile the 35GM and 35/1.8G are fantastic optically, and the physical size and weight of the GM is great for a 35/1.4. Canon has no RF20mm or RF24mm prime at all so Sony wins by default. Both very good lenses on the Sony system RF16/2.8 is cheap but has strong distortion and CA. Sony 14GM beats it but the price bracket is completely different Overall: Sony Wins, not even close For portrait length primes: Both Canon and Sony have 50/1.2 lenses, optically both are very good and probably almost indistinguishable. If you want to nitpick Sony has better bokeh, quieter and faster autofocus, and less CA. (This is from research online) Canon has 2?! 85/1.2 lenses while Sony “only” has an 85/1.4. Sigma also has a very strong 85mm.. I don’t know enough about the Canon 85/1.2 to comment on the optical differences. Optically the 85/1.4GM is very good and my main quibble with it is the poor minimum focusing distance There is no RF135mm and the 135GM is absolutely fantastic, Sony wins by default Overall : Advantage Sony For wide and standard zooms: Sony 12-24/2.8 and 12-24/4: Canon doesn’t have a 12mm so Sony wins by default. I probably won’t buy a lens this wide so I don’t care Sony 16-35 f2.8 vs. Canon RF 15-35 :Both should get the job done, neither really impress. The Sony is known to have allot of sample variation… The Canon is supposedly sharper in the corners and the Sony is supposedly sharper in the centre 24-70/2.8: I don’t know enough about the Canon but the Sony is only average in my book. The Sigma is also half the price and optically very decent. From Petapixel’s comparison they are optically similar enough https://petapixel.com/2020/01/13/mirrorless-24-70mm-shootout-which-lens-wins-in-sharpness-vs-expense/ 24-70/2 Very interesting lens from Canon, unfortunately it’s kinda soft wide open and very heavy and expensive. I’ll stick with the primes 24-105: not sure how they compare… For a budget 24-xx zoom I prefer the sigma 24-70/2.8 because it’s 2.8 Overall: Tie —————- Overall the Sony lens lineup is much more attractive (for me) the lack of wide RF primes is a very big deal breaker. Meanwhile the Sony wide primes are world class, especially the 35GM As far as the R6 and A7iv goes, the main advantage of the R6 is the 20fps burst. This could be a huge deal or completely unnecessary depending what you shoot. Unfortunately for the R6 “14 bit is only available with mechanical shutter and EFCS in single shots.” https://www.dpreview.com/forums/post/64849128 The A7iv wins on most other important points: video is much better and not limited to 30min 33 MP sensor 14 lossless raw possible with mechanical or electronic shutter, and possible in burst mode at approx 6fps or so at 10fps the viewfinder still updates. Only 8fps on canon Therefore… I’m sticking with Sony for another few years at least

Should I buy the Canon R6 Mark ii OR Sony A7IV?
My thoughts as someone who shoots families, portraits and weddings and owns an R6: it depends on your budget. The R6 is incredible and everything I would ever need in a camera (except when I shoot wildlife for fun, but that's for another day). Here's the big BUT: Canon doesn't allow for third party lenses for its' full frame mirrorless cameras. This is a pretty big deal to me. I usually like to go for L series primes and third party zooms because I am not made of money and my primary job is not photography (though I do a fair number of paid photography jobs year-round). If I went back to 2020 when I switched to mirrorless, and you told me I would be waiting at least 4 years before I had access to RF mount 3rd party lenses, I would have jumped ship to Sony or Nikon in a heartbeat.

Canon R6 Mark II or Sony A7 iv
Canon has taken anticompetitive action against third party lens manufacturers. So RF will never have a broad and cost effective selection like E-mount. Your existing M-glass are basically paperweights now. So you are starting fresh either way. Date your body, marry your glass. More on reddit.com

Deciding between the Canon R6 and Sony A7IV
Both are great cameras for pics but some prefer the ergonomics of Canon, deeper grip, easier to hold. On the other hand, Sony offers more custom function buttons. These kind of little things must be also considered before deciding. If you decide to go with Sony, you can also use canon EF lenses on it with an adapter. More on reddit.com

Should I buy the Canon R6 Mark ii OR Sony A7IV
I have the R6 II. A good friend of mine has the A7IV. It's been over a year since we bought our bodies. Over that time I've only become more convinced that the R6 II is the better body. The A7IV has a bit more resolution and slightly better noise, but the shutter system on the R6 II is VASTLY superior and much more useful. It's about the most well rounded full frame body out there. The AF is as good as it gets. The sensor is excellent. The ergonomics are excellent. It's reliable. It has no technical problems. And for me, it gets the most amazing shots I've ever gotten in my life. It's very difficult for me to imagine any advantage a more expensive body would offer. Nothing about the R5 would improve my pictures, and the R3 wouldn't add much to my capabilities either. More on reddit.com

November 9, 2021 - So when you go to either, go to video, you now get all the video menus. But if you don’t want to look at those which you don’t when you’re shooting stills. They go away when you’re in the still mode. The EVF on this camera is fabulous. It’s like a 3,680,000 dot EVF. So you look through and you just get a very clear clean picture. Now the back screen, the monitor in the back though is not near as good. It’s more like a 1,036,000 which falls way under the R6 which is at 1,620,000.
