K&F Concept EF-L – Canon EF Lens to L-Mount Mount Adapter

The K&F Concept EF-L adapter lets you mount Canon EF/EF-S-mount lenses on L-mount cameras. It has no electronic contacts and you focus manually all the way to infinity; the adapter cannot set the aperture of EF/EF-S lenses, which have no aperture ring. The body made of copper and aluminium alloy holds the lens firmly, and a red dot makes mounting and removal easy.

Canon EF lenses on L-Mount cameras

With the EF-L adapter you can attach Canon EF/EF-S-mount lenses to L-mount cameras and keep using them on a modern body. The adapter is precision-made, so the lens sits firmly and focuses all the way to infinity.

Solid metal construction

The adapter body is made of copper and aluminium alloy; it is durable and fits the lens and camera precisely, so the lens is held without play. A red dot makes mounting and removal easy.

Manual focus and aperture

You focus with the ring on the lens while the camera works in aperture priority or manual mode. EF/EF-S lenses have no aperture ring, and an adapter without electronic contacts cannot set their aperture. STM lenses (for example EF 50mm f/1.8 STM or EF-S 18-135mm IS STM) need power to focus and therefore cannot focus with this adapter.

Camera settings

Before first use, enable the option in the camera menu that allows the shutter to be released without a lens attached (Release w/o Lens). The camera does not recognise an adapter without contacts and would not release the shutter without this setting.

Compatible cameras

The adapter is designed for L-mount cameras, for example Leica SL, SL2, T, TL, TL2, CL; Panasonic Lumix S1, S1R, S1H; Sigma fp.

Before you order

You will find the mount type of your lens and camera in their manuals or in the technical specifications on the manufacturer's website. The EF-L adapter is designed for a Canon EF / EF-S lens on a L-Mount camera.
