- Allows owners of Sigma SA and Sigma Canon EF mount lenses to use with L-Mount attachments
- The MC-21 ring has 29 Sigma lenses that can be used with the L system.
- The compatibility of the lens you want to use is immediately visible thanks to the LED in the MC-21
- For future goals, data for their operation with MC-21 will be stored in the same lens
The MC-21 Mount Converter enables the use of Sigma SA-mount lenses on L-mount mirrorless camera bodies, and maintains full lens performance, including autofocus in AF-S mode and auto-exposure, as well as in-camera correction and image stabilization technologies. An integrated LED can be used to display select Sigma lens compatibility with the adapted camera body, and the adapter also has pre-loaded lens data to support peripheral illumination, chromatic aberration, and distortion corrective functions. In order to maintain a high degree of image quality, the interior of the adapter is flocked to reduce reflections, and it also retains full EXIF data to benefit post-production and file management. Additionally, a removable tripod mount is included for more stable mounting when working with heavier lenses.
