Sony camera owners with E-Mount systems rejoice! The new Mount Converter MC-11 allows you to use your Canon EF mount interchangeable lenses with the Sony E-mount camera body. The gadget 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, correct transverse chromatic aberration and distortion, and is fully compatible with the automatic exposure control of Sony E-mount camera bodies. Mount Converter MC-11 is ideal for professional photographers who use different camera systems depending on the subject, as well as amateur photographers who enjoy using a variety of camera systems. Increasing the compatibility of lenses with different camera systems makes these assets more valuable than ever. 

Excellent 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.

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. It is compatible with functions of the camera that maintain peripheral brightness and correct transverse chromatic aberration, distortion, and more. As new compatible lenses are released, control data for the adapter can be updated via a personal computer.

Optical Stabilization

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, the converter allows angle shake correction in the lens for superior corrective performance.

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.

Exif Data Compatibility

Lens type, focal length, F number, and other tags are embedded as Exif data in the image file.
