If there are any EOS-1D Mark III owners in the audience then please take heed on this firmware upgrade. If the errors on the Italian and Chinese menu screens put you into a fit of rage then immediately upgrade to v1.1.0. I’m not sure who would get annoyed with the camera not starting up properly when the battery is inserted, but this alleviates that problem as well. The look of images on the LCD monitor has also been spruced up. The upgrade fixes a problem when operating the Main, Quick Control and Vertical-grip Main dials as well as an autofocus issue.
