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

Canon R6 or the Sony A7 iv?

I guess I don’t know your criteria entirely but as a fellow outdoorsman, I appreciate the weight savings of mirrorless without sacrificing image quality. I moved to Fujifilm several years ago and have not looked back. I would encourage you to see if the X-T3, X-T4, or X-H2 models fit your criteria. They are crop sensor but still pack a punch and I don’t miss full frame even for my portrait work. I definitely appreciate the size and weight savings when I’m packing my kit in and out of a more remote location.

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

Sony A7IV vs Canon r6 Mark 2
I just made this switch actually lol. I switched because of other reasons though. Those being that the rolling shutter on the A7IV is real bad and the ibis is almost nonexistent. The Canon is more pleasurable to use, I could feel that right away. The ergonomics are unbelievably good on the Canon. As for video, well, the Canon has 4k60 without a crop which can be awesome for recording slow motion b-roll without worrying about trying to reframe a shot. So that’s nice. It also has 1080180. Which is unique. There are pros and cons to both but I feel the cons on the Sony are bigger than the Canon’s. For instance, the Canon only shoots in IPB. It doesn’t have all-i. Will you notice a difference? Probably not but if you zoom in to 200% and pixel peep, the Sony may have a slight edge in sharpness when using all-i over a compressed codec. The A7IV has a sensor readout speed of 27ms. That means any panning, tracking subjects, or shakiness will cause the static vertical lines in your shot to tilt or wobble. I experienced this recently on a shoot with my A7IV. An hour of footage with panning and tracking from a car was unusable. It ruined the project. This is something I consider to be a way bigger con over a tiny loss in sharpness in video. Same goes for ibis. The ibis doesn’t really do much on the Sony, and the active mode crops in a decent amount. But the canon combines its ibis with optical lens stabilization and creates a really steady looking video and sharper images at lower shutter speeds. So you can do a lot more handheld shots and leave the gimbal and tripod at home. Though this does come with a caveat at the current moment. Any lens wider than 24mm on the Canon will show wobbles in the corners of your video from the ibis. Some people don’t care as it isn’t overly noticeable, but it is there and you gotta take extra care to be as steady as possible to mitigate those odd looking wobbles. Canon could fix this with a firmware update and I hope they do, but that doesn’t apply to me because I never shoot under 24mm. It introduces too much distortion in your image, imo. The only way I would shoot wider than 24mm would be if I was filming action sports like skateboarding or snowboarding up close to the action. But if I were doing that I’d use a gimbal and turn the ibis off anyways. So basically, under 24mm you need a gimbal, above 24mm, you can do handheld just fine. Low light is definitely better on the canon since it has larger photosites. About 15% larger, so when you combine that with the good ibis, night shots and low light shots become amazing at both high and low shutter speeds. You can shoot at a lower iso in low light for sports, which is a huge plus. The A7IV has better dynamic range but it’s a VERY small margin in real world shooting. You wouldn’t see it right off the bat, but if you look at a picture for 10 seconds you would probably see it but not really care because it only brings back minor details in blown out areas. You can just dial it back in post on the canon and you see the same details in the highlights. For video it’s the same story, but I’ve found that even when bringing slog3 back to rec.709 the image still looks washed out like it’s got a layer filled with white overtop of it at 5-10% opacity. The Canon has more contrast in its video than the Sony. That usually means the shadows will be a bit more noisy but that can be easily fixed in post with some noise reduction and added sharpness. That’s personal preference though as many people prefer that slightly washed out look. I think the A7IV is a fantastic camera for studio work, and more static shots in both photo and video. But for movement and run and gun type of video shooting the canon is much better. The canon is also much better for photography with movement in it like sports, cars, subject tracking, wildlife, etc since you can get up to 1/16000 shutter speed. Can the Canon do studio work? Absolutely, like a beast. But the A7IV does have those slightly bigger images. Will clients notice? 99% of the time, no. Hell, you could shoot photos and videos with your phone and professional clients wouldn’t notice or care, as long as the end result looks good and is what they wanted. So in the end, the A7IV is probably better for studio work, anything on a tripod or without much movement. The Canon is better for sports, wildlife, really capturing any kind of movement. It’s a better camera for on-the-go shooting. More on reddit.com

If you look at the transition between the highlights and the shadows we’re starting to see some red banding. It’s starting to see this kind of blotchiness in her skin. That kind of red is starting to show up. We’re getting the highlights start to kind of just become more contrasty and a little more pronounced. Although it’s looking a little nicer in the R6 with regards to that transition.
