Sigma MC-21 Mount Converter - Sigma to L Mount
The Sigma MC-21 Mount Converter allows Sigma’s SA-mount lenses to be used on L-mount cameras, such as the Panasonic S1/S1R. Auto-exposure and high precision AF in AF-S mode is achieved (not compatible with AF-C). The MC-21 has a built-in tripod socket and LED that lets users know if the mounted lens is compatible or not, and when a lens firmware update is available.

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 optimised. 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.
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.
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.
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.
Whether the mounted lens is compatible or not is instantly visible from the colour 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.
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 autocrop function, mounting APS-C size image circle DC lenses to a camera body equipped with a 35mm full size sensor still allows immediate use for shooting.
