Frequently Asked Questions (FAQs)

1. Are M mount lenses full-frame?

Later variations of the M (9, M-E, Monochrom, 240, etc.) are full frame, while the original M8 is APS sensor size. In 2014 Leica introduced a second mirrorless camera type based around an APS sensor, the T, which uses a new set of new L-mount autofocus lenses (though it can use Leica M-mount lenses via an adapter).

2. What does M stand for Leica?

Overview. The Leica M mount was introduced in 1954 at that year's Photokina show, with the Leica M3 as its first camera. The 'M' stands for Messsucher or rangefinder in German. This new camera abandoned the M39 lens mount in favour of a new bayonet mount.

3. Is Leica M mount same as M42?

The M42 mount has in fact been used by so many manufacturers that it has come to be known as the Universal thread mount. The Leica M mount is a bayonet-type lens mount that was introduced in 1954, on the Leica M3. Bayonet-mount lenses are easier and faster to attach and remove than screw-mount lenses.
