K&F Concept LM-L – Leica M Lens to L-Mount Mount Adapter

The K&F Concept LM-L adapter mounts lenses with the Leica M mount on cameras with the L mount. It is purely mechanical, with no electronic contacts: focusing is done by hand on the lens and the aperture is set with the lens aperture ring. Precise machining ensures a firm connection without play.

Leica M lenses on L-Mount bodies

With the LM-L adapter, Leica M lenses can be used on a modern L-Mount body with everything it offers – a viewfinder with magnification for precise manual focusing, sensor stabilisation if the body has it, and current recording formats.

Precise connection

Precise machining ensures a firm connection without play.

Manual focus and aperture

The adapter has no electronic contacts and the camera does not recognise the lens – autofocus, aperture control from the body and lens data in EXIF do not work. Focus with the ring on the lens; magnification or focus peaking in the viewfinder makes precise focusing easier. The aperture is set with the aperture ring on the lens; lenses without an aperture ring cannot be stopped down with this adapter.

First use

Before the first shot, enable shutter release without a lens in the camera menu (on Sony “Release w/o Lens”, a similar option on other brands). Otherwise the body will not treat the adapter without contacts as an attached lens and will not release the shutter.

L mount

The L mount was developed jointly by Leica, Panasonic and Sigma. Do not confuse it with the Leica M and Leica R mounts – these are three different systems, so check the mount of your body before buying.

Compatible cameras
