As promised, Canon has released new firmware for its high-end EOS-1D Mark III digital SLR.

Earlier this month, the company said it planned to release version 1.0.9 of the built-in camera software for the photojournalist-oriented camera. Instead, Canon released version 1.1.0 for download, fixing a fifth problem with 1.0.9.
Version 1.0.9 of the firmware "reduces the tendency of the camera to autofocus on high-contrast backgrounds when shooting in conditions where autofocus detection is difficult, such as when the main subject is not completely covered by the autofocus frames or if the main subject's contrast is low," Canon said earlier. It also The new firmware improves images viewed on the LCD by applying a stronger sharpness setting; corrects a "rare" problem in which a selection dial wouldn't respond; fixes Italian and Chinese menu errors; and most prominently, "improves the consistency" of autofocus in some conditions.
On top of that, version 1.1.0 "fixes a rare phenomenon in which the camera cannot start normally when the battery is inserted," Canon said.
