The camera marks the return of eye-controlled autofocus, a feature not seen in a Canon camera since the Canon EOS 30V in April 2004.
Even though the camera was not officially released to the public, it was already used at the 2020 Summer Olympics in Japan.[6]
The EOS R3 won Camera Grand Prix 2022 Editors Choice Technology Award.[7]
In July 2022, EOS R3 firmware update 1.2.0, enabled this camera to shoot up to 50 frames at a custom high-speed continuous mode rate of 195 frames per second with full resolution in JPEG, HEIF or RAW format.[8][9]
