Mount Converter MC-21
The SIGMA Mount Converter MC-21 allows SIGMA SA-mount and SIGMA’s CANON EF-mount interchangeable lenses to be mounted on L-mount cameras.
• Fast and accurate AF
• Tripod mount included
• Exif data inclusion
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.
*Please make sure your camera is compatible.
Lens data is pre-loaded
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.
Fast and accurate auto focus
High precision AF photography in AF-S mode is achieved.
Note: Not compatible with AF-C mode.
Comes with a 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.
*The tool supplied makes attaching/detaching possible.
*Cannot be used in combinaion with teleconverter.
The inside surface of the barrel is covered with flocking to eliminate internal reflections.
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.
Whether the mounted lens is compatible or not is instantly visible from the color and the on/off of the MC-21's built-in LED. The LED also notifies the user when a lens firmware update is available.
