Sigma MC-31 Mount Converter PL-Mount to L-Mount

The Sigma MC-31 Mount Converter lets you mount PL-mount cinema lenses to L-mount camera bodies, giving filmmakers more flexibility when working with high-end glass. Built from solid aluminum and brass, this adapter is designed for durability and tight tolerances, making it a great fit for professional production environments.

It supports secure mounting with a shim-adjustable design to fine-tune flange distance for critical focus accuracy. The adapter also features a locking ring for added stability—especially important when using heavier cine lenses. With a tripod socket built in, it helps balance your rig and reduces strain on the camera mount.

Whether you're working with a Blackmagic Cinema Camera 6K (L-Mount), Panasonic LUMIX S series, or a Leica SL body, the MC-31 offers a reliable way to integrate your PL lens collection into modern mirrorless workflows.
