Product title: Sigma Mount Converter MC-11 for Sigma Mounts to Sony E Cameras
Product description: The new MOUNT CONVERTER MC-11 allows you to use your SIGMA SA mount interchangeable lenses with the Sony E-mount camera body. Until now, the market has seen the introduction of many methods for using lenses from one camera system with a body from a different system. In the digital age, however, camera systems have become much more complex, and it is challenging to create a mount converter that aligns both the mechanics and software of the lens and body. Creating a converter that matches lenses for current DSLRs to bodies for mirrorless interchangeable-lens camera systems is even more challenging. Now the market demands a converter that goes beyond simply aligning the flange back distance to retaining full functionality. 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 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. In addition, users of Sony E-mount camera bodies will enjoy an immediate increase in the number of lenses available to them. Compatibility:Cameras - Sony a7-series, a6000-series, a5000-series, and NEX-series mirrorless camera bodies.
Product feature: offered in both SA-Sony FE and Canon EOS EF-Sony FE version, offers full electronic control of the lens, including autofocus and aperture selection, Support for both in lens optical stabilizer or in camera shake reduction
