Search camera lenses on AmazonChoosing a camera
Look for the Leica M designation on the camera specification, then verify the exact model code and mount variant against its support page. The maker lists a 75 mm focal range and f/1.25 maximum aperture. A physical mount match is a starting point; still AF, movie AF, crop behavior, stabilization and firmware need separate checks.
Choosing a filter
A circular screw-in filter with a matching documented thread size is only a mechanical candidate. Magnetic filters, wide frames and stacked rings need separate system and vignetting checks. When no front thread is specified, do not buy a size from the focal length or barrel diameter.
