Sigma MC-11 Mount Converter – Canon EF Lens to Sony E Mount

The Sigma Mount Converter MC-11 incorporates the digital data necessary to provide fast and smooth AF for compatible lenses as well as OS features and functions of the camera that help control peripheral brightness and correct transverse chromatic aberration, distortion, and more. In addition, since Sony E-mount camera bodies do not require mechanical integration with lenses for aperture control, the Mount Converter MC-11 makes SIGMA SA mount interchangeable lenses and Sigma interchangeable lenses for Canon cameras fully compatible with the automatic exposure control of Sony E-mount camera bodies.

More flexible use of valuable lens assets
With the MOUNT CONVERTER MC-11, users of SIGMA SA mount interchangeable lenses and SIGMA EOS mount interchangeable lenses for Canon camera bodies* can use them as is with Sony E-mount camera systems. Users of multiple mounts will enjoy more flexible use of their valuable lens assets.

19 interchangeable SIGMA lenses available for Sony E-mount camera bodies
The MOUNT CONVERTER MC-11 gives Sony E-mount camera body users access to a total of 19 SIGMA interchangeable lenses. Thanks to compatibility with auto-image area setting functionality, SIGMA DC lenses for APS-C sensors can be used with camera bodies with full-size sensors without the need for any special operation. Compatible SIGMA DC lenses can therefore be freely used with Sony E-mount camera bodies.

Fast and smooth autofocus performance
When used with a camera body that is compatible with Fast Hybrid AF, AF-S mode delivers extremely fast and smooth autofocus performance. With other camera bodies, contrast detection AF offers very high-precision autofocusing.

Easy-to-use interface
The LED display on the MOUNT CONVERTER MC-11 makes it easy to know whether an attached lens is compatible or not and whether the mount converter control data needs to be updated for operation with that lens

Includes necessary data
MOUNT CONVERTER MC-11 incorporates the data necessary for each compatible lens and uses a dedicated control program to optimize AF drive, aperture control, and other functions. This data is compatible with functions of the camera that help control peripheral brightness and correct transverse chromatic aberration, distortion, and more. As new compatible lenses are released, control data for MOUNT CONVERTER MC-11 can be updated via a personal computer.

Compatible with optical stabilization features of both lens and camera body
The compatibility of MOUNT CONVERTER MC-11 with the OS features of both the lens and the camera body makes possible superior correction of camera shake and other stability issues. When used with a camera body that features an OS function, MOUNT CONVERTER MC-11 allows angle shake correction in the lens for superior corrective performance.

Additional Features

• Compatibility with Exif data: Lens type, focal length, F number, and other tags are embedded as Exif data in the image file.
• Flocking inside barrel helps prevent internal reflections:MOUNT CONVERTER MC-11 features flocking in its interior to help prevent internal reflections and a reduction in lens performance.
