Canon has released new firmware for the Canon EOS R to add compatibility for their new 600mm f/11 STM, 800mm f/11 STM, RF 1.4x & RF 2.0x teleconverters and the new LP-E6NH battery. They say that “operation of playing back through the multi-function bar has been improved”, too. No other changes have been mentioned.
They’ve also released firmware updates for seven of their RF mount lenses to improve compatibility with the in-body image stabilization found in the new Canon EOS R5 and EOS R6 mirrorless cameras for increased stability.
Canon USA’s website is still down due to recent issues, although the firmware is available to download from Canon Canada.
