Some Canon 1D Mark III owners are reporting that Canon Service Centers are installing firmware v1.0.9 on their DSLRs. Following is the text of the letter that is suposedly returned with the updated cameras ...
We have updated the firmware in your camera to the latest version (Version 1.0.9). This firmware update incorporates the following improvements and fixes:
1. Improves the look of images when enlarged on the LCD monitor. Applies a slightly stronger sharpness setting to the LCD monitor when images are enlarged.
2. Counter measures for Main Dial response errors (Main, Quick Control, Vertical-grip Main). Fixes a rare response error in the Main Dials in which they either did not respond when rotated or would change several clicks' worth even if only clicked once.
3. Improves the consistency of AI Servo AF under certain conditions. Reduces the tendency of the camera to autofocus on high-contrast backgrounds when shooting in conditions where AF detection is difficult, such as when the main subject is not completely covered by the AF frames or if the main subject's contrast is low.
4. Corrects errors in the Italian and Simplified Chinese menu screens.
Please note that this Version 1.0.9 firmware will be made available for download from the Web at the end of July. However you will not need to take any action as your camera has already been updated.
