Canon released a firmware update today for the EOD 6D DSLR Camera. The firmware, version 1.1.6 incorporates the following fixes:
1. Fixes a phenomenon in which the camera may not first use the center AF point to focus, when the AF point selection is set to automatic in AI Servo AF mode.
2. Fixes a phenomenon in which focus cannot be finely adjusted with specific lenses when shooting remotely with EOS Utility software.
3. Corrects some Ukrainian language displayed on the menu for ISO Setting.
Check your camera’s current firmware version before you apply this fix. Firmware Version 1.1.6 is for cameras with firmware up to Version 1.1.4. If the camera’s firmware is already Version 1.1.6, it is not necessary to update the firmware. If the firmware is updated from version 1.1.3 or before, the following setting will be reset to default.
Menu > Custom Function> C.Fn II: Autofocus > AF Microadjustment> 1: All by same amount
When updating the firmware of the camera, you should review the instructions thoroughly before you download the firmware.
