The SIGMA MOUNT CONVERTER MC-21 allows SIGMA SA mount and SIGMA’s CANON EF mount interchangeable lens owners to use their lens investment on L-Mount camera bodies.
The converter allows more freedom of choice for L-Mount cameras, enhancing the extensibility of the L-Mount system.
Attaching the MC-21 to your collection of SIGMA SA mount and SIGMA’s CANON EF mount compatible lenses allows them to be used as L-Mount system lenses, promoting the effective use of valuable lenses already owned.

Running the data pre-loaded in the MC-21 for each lens by the special control program, autofocus and aperture control have been optimized. 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.
