The SIGMA MOUNT CONVERTER MC-21 allows SIGMA SA mount and SIGMA’s CANON EF mount interchangeable lens owners to use their lens investment on L-Mount camera bodies. The converter allows more freedom of choice for L-Mount cameras from SIGMA, Leica Camera and Panasonic, 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.
※See the list of compatible lenses below.

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.

Fast and accurate auto focus

High precision AF photography in AF-S mode is achieved.
* Not compatible with AF-C mode.

Simple interface

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.

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.

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.

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.

It's holding up better than I thought it would
Style: Snake
*EDIT* I originally gave this toy a 1 star rating. I changed that to a 4. Even though my dog immediately put holes in it, it's still holding up. She absolutely loves her Snakey, and takes it to bed with her. She hasn't even chewed the eyes off, like she would normally do. There's even still a piece of the tongue left lol! I gave this to my dog tonight. She's already torn a hole in the tail. I just found a hole next to a squeaker, and she's almost chewed the tongue off. This toy is not durable at all. I do not recommend this for any dog that likes to chew.

Not recommended for an aggressive chewer.
Style: Crocodile, Style: Crocodile
24 hrs. after giving this to my Frenchton, all 3 squeakers were out and disabled, one foot remained, head was half way off, back end was chewed away. This alligator is no match for an aggressive chewer.

It is good for tug a war
Style: Snake
The squeakers did not last very long with my poodle puppy. That was a disappointment. He does like to play tug a war with it. So I gave it three stars.
