Addressed an issue that sometimes caused errors with certain UHS-II SD memory cards. As we were able to confirm that these were read errors arising not in the camera but in the cards themselves, we addressed the issue with a work-around that switches temporarily to UHS-I mode when a card-side error occurs in UHS-II mode. The camera switches back to UHS-II mode when turned off and then on again or when the standby timer restarts. Card-side read errors may still occur after the update, albeit very infrequently.
EDIT: So were not for the fixes the solution would be Canon with Lexar and Nikon with Sandisk ;D ;D ;D
