Sigma MC-11 EF-E Lens Adapter

The Sigma MC-11 is a mount converter that lets Canon EF-mount lenses work on Sony E-mount mirrorless bodies. It keeps autofocus and auto-exposure running, so an EF lens behaves like a native one on the camera.

The adapter passes through in-camera correction and image stabilisation, and an integrated LED shows the compatibility status of Sigma lenses with the camera body. The inside is flocked to cut reflections, which helps hold contrast when shooting towards a light source with a fast EF lens.

It is a compact electronic adapter, so it suits small Sony bodies such as the a7 series where you want to use an EF lens collection without losing autofocus. Full Exif data is retained in the files, so lens information stays intact for post-production and file management. It is a small, light adapter to carry.
