The question of the Sony a9 II versus the Canon EOS R6 II certainly makes sense. Although there are some more capable cameras out there like the Sony a1, the Nikon Z9, and the Canon R5, there is still a place for a more midrange action camera that won’t break the bank. And although the Sony a9 II was quite expensive when it first came out, the large number of used copies available means it really does make sense to compare these two cameras.
I already compared the original Sony a9 to the Canon EOS R6 II. Of course, in that case, there is a bit more favour for the original a9 due to price. However, even though the a9 II is more expensive, it also is even more capable than its predecessor.
And in this regard, the Sony a9 II is certainly the more capable action camera. Unlike the Canon R6 II, it has a stacked shutter, meaning no rolling shutter effects and more autofocus calculations. The Sony a9 II also has a massively larger buffer at 239 frames at 20FPS over the R6’s buffer, which is still only 110 frames even at 10FPS.
Are there any advantages to the Canon R6 II? Indeed there are. Of course the obvious is the MSRP, which matters a lot if you’re buying new. Canon undoubtedly gives you a lot of camera for just $2500, though you can easily find a used a9 II for that price. And since the a9 II didn’t improve much on the video front, the Canon R6 II is a much better video camera.
If a friend asked me which camera to get, I’d just say: the a9 II for birds and fast action, but the R6 II for everything else, especially video!
What does the Sony a9 II offer over the Canon EOS R6 II?
- Better autofocus and a stacked sensor
- Better battery life when using the viewfinder, with approximately 180 more shots according to CIPA measurements
What does the Canon EOS R6 II offer over the Sony a9 II?
