Summary and Recommendations
As you can see, the Canon EOS R5 and Sony a9 II are similar cameras, with one major exception: the 45MP higher resolution of the Canon EOS R5 over the Sony a9 II’s 24.2MP. This extra resolution will be appreciated by those who print large or need to crop.
The 45MP resolution of the R5 enables it to shoot 8K video, although with time limits due to heating. The Sony a9 II with its 24MP sensor is not capable of 8K video. However, there is one characteristic of the Sony a9 II that could be very useful for video shooters: no practical recording limits, whereas the R5 is limited at 30 minutes. It also has a longer battery life, which is especially important when shooting video.
The Sony a9 II costs more, which may seem surprising because of the lower resolution, and otherwise similar specs. So is there any reason to buy the Sony a9 II? Part of the allure of Sony comes from its lens ecosystem. Due to Sony’s open licensing system for its mount, it simply has far more lenses offered. Beyond that, some wildlife photographers actually prefer lower resolution because it saves hard drive space and makes their post-processing faster.
There’s also the potential cost of switching. As a general rule, I don’t recommend switching camera brands, because it’s an expensive proposition that usually doesn’t offer as many benefits as you’d think. If you’re an existing Canon shooter, I would stick with the Canon EOS R5. If you’re an existing Sony shooter, I would stick with the a9 II – or with another Sony camera like perhaps the a7R V if you need higher resolution.
In short, in most real-world regards, the Canon R5 and Sony a9 II are fairly close and they are both very capable cameras. The higher resolution of the EOS R5 makes it probably the winner in this specific head-to-head, but it really depends on what you shoot. You definitely can’t go wrong either way.
