Sigma MC-11 Mount Converter/Lens Adapter (Sigma EF-Mount Lenses to Sony E)

Sigma MC-11 Mount Converter / Lens Adapter – Unlock Your Sigma EF/SA Lenses on Sony E-Mount Bodies
With the Sigma MC-11 Mount Converter, you gain the freedom to use your precious Sigma EF-mount or SA-mount lenses on Sony E-mount (FE) mirrorless cameras—with full electronic control, fast autofocus, and seamless integration. Whether you’re migrating to Sony or just want to extend your lens arsenal, the MC-11 preserves optical performance while enabling aperture control, EXIF data transfer, and in-camera corrections (chromatic aberration, distortion, peripheral brightness). Its robust metal build, flocked interior to reduce flare, and firmware upgrade support ensure longevity and adaptability. The converter even supports optical stabilization features when present, making it an indispensable companion for hybrid shooters who demand flexibility without sacrificing quality.

Key Features

• Adapts Sigma EF- and SA-mount lenses for full compatibility with Sony E-mount / FE mirrorless bodies, expanding your lens arsenal without buying new lenses. 

• Full electronic integration: retains autofocus (AF), auto-exposure (AE), and lens aperture control.

• Supports in-camera correction features like peripheral brightness, distortion, and transverse chromatic aberration to maintain image quality close to native lens performance. 

• Optical Stabilization (OS) compatibility: works with both lens-based and body-based stabilization systems for reduced camera shake and sharper images. 

• LED compatibility indicator: a built-in LED light shows whether the attached lens is fully supported, or whether firmware for lens or the converter itself needs updating. 

• Firmware upgradeability using Sigma Optimization Pro and USB interface (adapter has USB port) to keep compatibility with newer lenses/cameras. 

• Flocked interior barrel: minimizes reflections and flare inside the adapter, preserving contrast and image sharpness. 

• EXIF data retention: preserves full metadata — lens type, focal length, aperture, etc. — for efficient post-processing and record-keeping. 

• Solid metal build: durable construction for regular shooting; solid mechanical fit ensures lens mount stability. 

• Broad lens compatibility: official support for many Sigma EF/SA lenses (including “Art”, “Sports”, “Contemporary” lines) ensuring high image quality across wide angle, zoom, and prime lenses.
