This adapter allows the use of Canon EF / EF-S mount lenses on Sony cameras with the Sony E-mount system. Now, lenses for full-frame and APS-C cameras can not only be connected to mirrorless cameras but also retain their full functionality — the Sigma MC-11 provides built-in control of lens parameters and focusing directly during shooting, ensuring fast and reliable autofocus, optical image stabilization, and support for special camera functions that manage corner brightness, reduce chromatic aberration and distortion, and more. Since Sony E-mount cameras lack mechanical aperture control, the MC-11 adapter makes Canon EF mount lenses fully compatible with the automatic exposure system of Sony E cameras.
The MC-11 adapter is an excellent tool for professional photographers using multiple camera systems for different types of shooting, as well as for advanced enthusiasts who want to achieve versatility across different camera systems.
