The Sigma MC-21 Lens Adapter allows you to use Sigma EF-mount lenses on Panasonic DC-S1 and Panasonic DC-S1R camera bodies.

Sigma EF Lens To L-Mount Camera

The MC-21 Mount Converter enables the use of Sigma EF-mount lenses on L-mount mirrorless camera bodies. It maintains full lens performance including autofocus in AF-S mode and auto-exposure, as well as in-camera correction and image stabilization technologies.

Electronic Communication

The adapter retains full EXIF data to benefit post-production and file management. The Sigma adapter also supports the Image Stabilization function of compatible lenses, allowing you to shoot at slower shutter speeds and help eliminate camera shake.

Powered by the Camera Body

This adapter doesn’t require any additional power source. On top of that, the adapter’s built-in LED immediately tells you whether or not the mounted lens is compatible. The adapter also has pre-loaded lens data to support peripheral illumination, chromatic aberration, and corrective distortion functions.

Limited Compatibility

The MC-21 Adapter supports a select number of Sigma’s Global Vision line of lenses and may or may not be suitable for use with other manufacturers' EF-mount lenses.

Tripod Mount

Additionally, a removable tripod mount is included for more stable mounting when working with heavier lenses.
