Hi, is still recommended use 1.1.3 just for RAW video instead of 1.2.3 with clean HDMI?
Thanks
Firmware 1.2.3 is required if need one of those features from Canon:
clean HDMI out
dual monitor support
AF at f/8 with teleconverters
If you don't need anything from the above list, please consider downgrading to 1.1.3.
