A ne.w device that expands the possibilities of lenses, making them more valuable than ever.The ne.w MOUNT CONVERTER MC-11 allows you to use your SIGMA SA mount and SIGMA EOS 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 and SIGMA interchangeable lenses for Canon cameras 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.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.27 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 27 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.Camera: 9, 7 series, NEX series, 5000 series, 6000 series*1Lens- 35mm full-size:- 12-24mm F4 DG HSM(Art)- 24-35mm F2 DG HSM(Art)- 24-70mm F2.8 DG OS HSM(Art)- 24-105mm F4 DG OS HSM(Art)- 100-400mm F5-6.3 DG OS HSM(Contemporary)- 120-300mm F2.8 DG OS HSM(Sports)- 150-600mm F5-6.3 DG OS HSM(Sports)- 150-600mm F5-6.3 DG OS HSM(Contemporary)- 14mm F1.8 DG HSM(Art)- 20mm F1.4 DG HSM(Art)- 24mm F1.4 DG HSM(Art)- 35mm F1.4 DG HSM(Art)- 50mm F1.4 DG HSM(Art)- 85mm F1.4 DG HSM(Art)- 135mm F1.8 DG HSM(Art)- 500mm F4 DG OS HSM(Sports)APS-C:- 17-70mm F2.8-4 DC MACRO OS HSM(Contemporary)- 18-35mm F1.8 DC HSM(Art)- 18-200mm F3.5-6.3 DC MACRO OS HSM(Contemporary)- 18-300mm F3.5-6.3 DC MACRO OS HSM(Contemporary)- 50-100mm F1.8 DC HSM (Art)- 30mm F1.4 DC HSM(Art)- 19mm F2.8 DN(Art)*2- 30mm F2.8 DN(Art)*2- 60mm F2.
