Sigma MC-21 Adaptor for Sigma SA to Laica L-Mount

The Sigma Mount Converter MC-21 allows lens owners with Sigma SA and Sigma Canon EF mount lenses to use with L-Mount camera bodies. This allows you to choose between different machine bodies and increases the versatility of the L system. Using the MC-21 ring, Sigma SA and Sigma Canon EF compatible lenses can be used as L system lenses. The MC-21 ring brings 29 Sigma lenses that can be used with the L System. With the auto-crop function, APS-C lenses can be mounted on full frame cameras. The compatibility of the lens you want to use is immediately visible thanks to the LED present in the MC-21. The LED also alerts you if a new firmware upgrade is available on your lens. With the pre-loaded data in the MC-21 for each lens, control of autofocus and diaphragm has been optimised. As for future lenses, data for their operation with MC-21 will be stored in the lens itself. This means no MC-21 firmware updates are required to use new goals. The MC-21 also supports camera correction functions such as peripheral lighting, chromatic aberration and distortion. The lenses without the tripod bracket can use the MC-21 lens. Against internal reflections, the interior is treated with anti-glare material. High accuracy AF in AF-S shooting mode (not compatible with AF-C shooting) Lens information, focal length, F value and other information are included as Exif in each image file. https://www.sigma-global.com/en/lenses/cas roduct/accessories/mount-converter/#mc-21
