Sigma Mount Converter MC-21 (EF to L-Mount)



The MC-21 allows you to use your SIGMA EOS mount interchangeable lenses with the Panasonic L-mount camera bodies.

Out of Stock


The SIGMA MOUNT CONVERTER MC-21 allows 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.



Effective use of lens investment.
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.


29 interchangeable lenses available to be used for L-Mount cameras
The MC-21 increases the number of interchangeable lenses manufactured by SIGMA that can be used with the L-Mount system by 29 lenses. Compatible with the auto-crop function, mounting APS-C size image circle DC lenses to a camera body equipped with a 35mm full frame sensor still allows immediate use for shooting.



Lens data is preloaded
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 the correction functions of the camera such as peripheral illumination, chromatic aberration of magnification, and distortion.



Fast and accurate autofocus
High precision AF photography in AF-S mode is achieved.



Comes with Tripod Socket
Equipped with a socket for attaching the tripod. Lenses not equipped with a tripod socket can be used by mounting the tripod to the MC-21.
