Canon EOS R3, EOS R5MK2 and More Firmware Updates September 2025

During my last few days in Greenland (I am currently in Iceland wrapping up the extension trip), Canon updated firmware for the EOS R3, EOS R5MK2 and many other cameras in the line-up. Most of the updates are bug fixes, although some cameras got support for the new LP-E6P. You can download firmware updates through the Camera Connect app or directly from a Canon website. Personally, I find the Canon Camera Connect app to be the easiest and fastest. I updated my R3 in the field in less than ten minutes with my iPhone while waiting for the clouds to gather after the morning shoot here in Iceland.
