New Canon EOS 7D Mark II Firmware Version 1.0.5 Corrects Multiple Issues

Canon has released Firmware Version 1.0.5 for the EOS 7D Mark II, and it's release description shows it includes the following changes:
  1. 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.
  2. Fixes a phenomenon in which, in very rare cases, the "Peripheral illumination correction" is applied inconsistently.
  3. 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.
  4. Fixes a processing error in relation to the leap second for the "Geotag information appended to image" and "Log data" GPS functions.
  5. Fixes a phenomenon, where at the time of shooting in very rare cases "Err 70" occurs, or the shutter does not release.
Please note that after updating the firmware, you should reconfirm any AF Microadjustment you may have set for your EF 16-35mm f/2.8L USM or EF-S 17-55mm f/2.8 IS USM lens.
