Active Lock
The Active Lock design restricts movement between the lens and the camera without the need for additional adjustment.
The DZOFilm Octopus EF → L-Mount is a mechanical adapter for using Canon EF lenses on cameras with an L-Mount. The active lock creates a secure, wobble-free connection; stainless steel, aluminum, internal knurling, and a 1/4″-20 mounting foot help maintain rig stability and focus at infinity.

Octopus allows you to use Canon EF lenses on an L-Mount body. The active lock is designed for a secure connection without play or wobble when working with cine lenses and a rig.
It is a purely mechanical adapter with no optical elements; therefore, when properly mounted, it does not cause image cropping or vignetting on its own.

The precision-machined flange maintains the ability to focus to infinity for accurate long-distance work.
The 1/4″-20 threaded support takes some of the load off longer lenses and reduces stress on the mount.
The combination of stainless steel and aluminum is designed for a durable connection that withstands frequent handling. The internal fluting minimizes reflections and stray light so they don’t interfere with the image.
