Zeiss ZM 35mm f/1.4 Distagon

Lens Coding for Zeiss ZM 35mm f/1.4 Zeiss Distagon

re: Lens Coding for Lenses Without 6-bit Code

Caution: using the wrong Lens Profile results in a capture whose data is irrevocably modified according to the lens profile, including the RAW capture. The coding corrects for vignetting and color shading (though not distortion or chromatic aberration).

If the lens is uncoded, or the lens is a non-Leica lens, or some glitch occurs (eg dirty contacts), the Lens Profile can be set to any Leica M or Leica R lens. However, the M cameras only allow choosing lens codings corresponding to lenses which at one time lacked 6-bit codes.

The best solution is to code the lens physically, so that the camera recognizes it. See Lens Coding for Lenses Without 6-bit Code and zzz.
