Sigma MC-21 Mount Converter/Lens Adapter (Sigma EF-Mount Lenses to L-Mount Camera)
The Sigma MC-21 mount converter is designed for photographers who own Sigma EF-Mount lenses and want to use them seamlessly with L-Mount cameras, such as Panasonic Lumix S series, Leica SL models, and Sigma’s own fp cameras. It preserves core electronic communication between the lens and camera body, ensuring metadata transfer, aperture control, and autofocus functionality for still photography. This makes it a practical solution for expanding lens options without fully switching systems.
Constructed with durability in mind, the MC-21 features a robust metal build and includes a tripod mount socket to relieve strain when using heavier telephoto lenses. With support for firmware updates, it stays compatible with the latest Sigma lenses and L-Mount cameras, ensuring future-proof usability. For photographers seeking flexibility between EF and L-Mount ecosystems, the MC-21 provides a reliable and efficient bridge.
