Sigma MC-11 Mount Converter/Lens Adapter

The Sigma MC-11 Mount Converter is a high-performance lens adapter that allows you to use Sigma SA-mount or Canon EF-mount lenses on Sony E-mount mirrorless cameras. Designed to maintain full lens functionality, the adapter supports autofocus, auto-exposure, optical stabilization, and lens metadata transmission, enabling smooth integration between the adapted lens and Sony camera body.

Equipped with an embedded control chip, the MC-11 ensures accurate communication between the lens and camera, optimizing AF performance and compatibility. It also includes built-in LED indicators that let you know whether the attached lens is fully compatible, requires a firmware update, or is not compatible—providing quick and convenient feedback to the user.

The adapter’s internal design features black flocking that reduces internal reflections and helps maintain high image quality by minimizing flare and ghosting. Solidly constructed with a durable metal mount, the MC-11 provides a secure and stable connection for a wide range of lenses.

Ideal for photographers who want to use their existing Sigma (and select Canon EF) lenses on Sony E-mount full-frame or APS-C bodies, the Sigma MC-11 offers exceptional versatility without compromising performance.
