Attaching the MC-21 to Canon EF mount lenses allows them to be used as L-Mount system lenses.

Fast and accurate auto focus

High precision AF photography in AF-S mode is achieved. (Not compatible with AF-C mode.)

Lens data is pre-loaded

By running the data pre-loaded in the MC-21 for each lens by the special control program, autofocus and aperture control have been optimised. Regarding lenses to be released in the future, data for operating these lenses via the MC-21 will be stored in the lens. It means no firmware updates of the MC-21 will be required to use those new lenses. In addition, the MC-21 also supports correction functions of camera such as peripheral illumination, chromatic aberration of magnification, and distortion.

Tripod mount

Equipped with a socket for attaching a tripod.

Inside flocking

To prevent a reduction in lens performance due to internal reflections, the inside surface of the barrel is covered with flocking.

Inclusion in Exif data

Information such as lens type, focal length, F number, and other tags are embedded as Exif data in each image file.
