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.
