| p.2 #8 · Canon EOS 5D Mark III Firmware Version 1.2.3 |
FW from april 2013 is not minor, I believe they enabled F8 focusing.
True, that and a few other things might be considered major by many users. The flashing red focus points in servo may be annoying to some, but are sometimes a great help, and were undoubtedly about the best that could be done with the new viewfinder hardware (LCD overlay, side illumination, etc.). There are choices in how you configure it.
I've never lost any settings when upgrading Canon FW, but I still agree with EBH that it would be better to have the ability to backup to a card. I always do that with my 1D bodies, just haven't needed to reload in the 6 or 8 years I've bothered to do that.
