Precision. Stability. Confidence—Redefined.
Designed for filmmakers who demand absolute rigidity from their lens mounts, the Simmod Canon EF to L-Mount Positive Locking Adapter delivers a rock-solid connection between your Canon EF lenses and L-mount cinema or mirrorless bodies. Built for the modern cinematographer, this adapter eliminates rotational play and ensures your lens stays perfectly secured—no matter the rig, no matter the shot.
 
Engineered for Professional Cinema Use
Machined from high-grade aluminum alloys using our 5-axis CNC process, each adapter maintains exacting tolerances for flawless alignment. The positive-lock collar provides a secure, indexed locking mechanism identical to true PL-style mounts, distributing torque evenly and preventing lens twist during follow-focus pulls, gimbal work, or heavy cine-rig setups.
 
Zero-Play, Zero-Compromise
Unlike friction-based adapters, our positive-locking system clamps the EF lens in place, converting it into a stable, cinema-ready mount interface. Whether you’re running lightweight still lenses or fully cine-modded EF glass, the result is the same: no shift, no rattle, no surprises.
 
Optimized for L-Mount Bodies
Compatible with Panasonic, Sigma, and Leica L-mount cameras, this adapter preserves optical performance with a precision-machined flange distance that guarantees accurate infinity focus. Internal surfaces feature a matte-black, anti-reflection coating to reduce stray light and enhance contrast.
