EOS 7D Mark II Firmware Update Version 1.0.5

Firmware Version 1.0.5 incorporates a number of fixes and improvements.

Improves AF accuracy when used in combination with the EF 16-35mm f/2.8L USM lens or EF-S 17-55mm f/2.8 IS USM lens.
Fixes a phenomenon in which, in very rare cases, the “Peripheral illumination correction” is applied inconsistently.
Fixes a phenomenon in which, while performing an EF lens firmware update, the progress bar displayed on the LCD monitor may freeze at 100% even though the update has been completed.
Fixes a processing error in relating to the leap second for the “Geotag information appended to image” and “Log data” GPS functions.
Fixes a phenomenon, where at the time of shooting in very rare cases “Err 70” occurs, or the shutter does not release.
Please note:

After updating the firmware, you should reconfirm any AF Microadjustment you may have set for your EF 16-35mm f/2.8 USM or EF-S 17-55mm f/2.8 IS USM lens.
