With each new mirrorless camera system, hope springs eternal even as basic physical facts are ignored. Optical design of Leica M lenses was for film (no sensor cover glass) or presumably for 0.8mm sensor cover class for newer lenses designed at the time of Leica M digital cameras—Leica does not indicate what the design parameters are with regards to digital
