The Canon EOS R6 is the very accomplished little brother of the hugely popular EOS R5 full frame mirrorless camera. It features the same 20 megapixel CMOS sensor found in the professional 1D X Mark III. The R6 is capable of capturing 4K 60p Raw video.
A Dual Pixel AF II system, great image stabilization, and burst shooting up to 20 fps make this a great choice for underwater action shooting. The 3.69 million dot OLED EVF (electronic viewfinder) is perfect for both framing and reviewing images. The EOS R6 has a CIPA battery life rating of 360 shots per charge.
"The R6 ranks even better than the R5 for low light capability - making it a compelling camera for cold water underwater photographers. Overall, the R6 is the more rational choice for photographers looking for pro and enthusiast-level performance at a great price point." -Nirupam Nigam, Bluewater Photo
The savings over the R5 (about $1400US) will go a long way towards paying for the housing... assuming you're sticking with us. Unless you're a videophile and need the R5's 8K and slow motion specs, we recommend you pocket the cash.
