Quick Answer

To connect a PL lens to an L mount camera, use a precision mechanical adapter such as the DZOFilm Octopus PL to L Mount adapter. The adapter maintains the correct flange focal distance between the PL lens and the shorter Leica L camera mount.

Why You Need a Dedicated PL to L Mount Adapter

PL mount cinema lenses have a longer flange focal distance than Leica L mount cameras. A simple step-up ring or generic adapter will not preserve the correct optical spacing, leading to soft focus or infinity focus errors. A precision adapter like the DZOFilm Octopus is machined to hold the exact mechanical relationship required.

Common Mistake: Forgetting Lens Support

PL cinema lenses are often heavier than still lenses. Mounting a long or heavy PL lens without a lens support can stress the camera's lens mount and cause alignment drift over time. Always use a lens support bracket or rail-mounted support when the lens extends beyond the adapter.

Step-by-Step: Mounting a PL Lens on an L Mount Camera

  1. Attach the Adapter to the Camera: Align the adapter's L mount side with the camera body's mount. Rotate gently until it clicks or locks into place. Do not force it. Check that the adapter sits flush and locks securely before mounting the lens.
  2. Mount the PL Lens onto the Adapter: Line up the PL lens's alignment pin with the adapter's PL mount slot. Insert the lens and rotate the locking ring clockwise until tight. Avoid overtightening. If the lens does not seat smoothly, stop and check for debris or misalignment.
  3. Secure the Lens with Support: Attach a lens support bracket to your rig's rod system and adjust it to cradle the lens barrel. Tighten the support screws just enough to hold the lens steady. A supported lens prevents strain on the adapter and camera mount during use.
  4. Test Focus and Infinity Stop: Set the lens to infinity and check through the viewfinder or monitor that distant objects are sharp. If not, recheck the adapter's seating. If infinity is soft, the adapter may not be fully seated or may be incompatible with that specific lens.

  • DZOFilm Octopus Adapter (PL to L Mount): The DZOFilm Octopus PL to Leica L adapter is a precision mechanical mount adapter for using compatible ARRI PL cinema lenses on a Leica L camera body. It maintains the required flange relationship, so your PL lens focuses correctly at all distances on an L mount camera.
