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

Sigma MC-11 Mount Converter (Canon EF to Sony E)
The Sigma MC-11 Mount Converter is a sophisticated bridge that allows you to use your Canon EF-mount Sigma lenses on Sony E-mount mirrorless camera bodies. Unlike standard adapters, the MC-11 is engineered to maintain full communication between the lens and the camera, ensuring that autofocus, auto-exposure, and in-camera correction technologies function seamlessly. This makes it an invaluable tool for photographers transitioning to Sony mirrorless systems while retaining their high-quality Sigma glass.

Full Integration and Performance
Native-Level Functionality: The MC-11 supports high-speed autofocus (including Phase-Detection AF) and auto-exposure. It is designed to make adapted lenses perform as if they were native Sony E-mount optics.

Correction Support: Supports in-camera peripheral illumination, chromatic aberration, and distortion correction features.

Image Stabilization: Fully compatible with both lens-based optical stabilization and Sony’s in-body sensor-shift stabilization (IBIS).

Exif Data Retention: All lens information, including focal length and aperture settings, is recorded in the image file’s Exif data for easier post-production and organization.

Professional Build Quality
Flocked Interior: The inside of the adapter is lined with a dark, flocked material to eliminate internal reflections and maintain maximum image contrast.

LED Status Indicator: An integrated LED light provides instant feedback on lens compatibility. A green light confirms the lens is fully compatible, while an orange light indicates a firmware update may be required via a Sigma USB Dock.

Firmware Updatable: The converter itself can be updated to ensure compatibility with future lenses and camera bodies.

Compatibility Overview
The MC-11 is specifically optimized for Sigma-brand EF-mount lenses. While other manufacturers’ EF-mount lenses may physically fit, Sigma guarantees full performance primarily with their own Global Vision (Art, Contemporary, and Sports) lineup.
