PL-Mount Zeiss Cine Lens to Blackmagic Micro 4/3 Cine Cameras. The Metabones PL to BMPCC4K Speed Booster CINE T ULTRA 0.71x adapter was designed specifically to let you mount PL-mount Zeiss lenses on Blackmagic Micro 4/3-mount cine cameras, like the Blackmagic Design Pocket Cinema Camera 4K and the Blackmagic Design Micro Studio Camera 4K.

Wider Focal Length and Increased Aperture. This BMPCC 4K version of the Speed Booster CINE T ULTRA widens the mounted lens’s focal length by 0.71x, effectively reducing the overall sensor crop factor from 2.02x to 1.43×. Additionally, the adapter increases the maximum aperture of the mounted lens by 1 stop, with a maximum output aperture of f/0.9.

Sturdy Design with Built-In Tripod Foot. The aluminum barrel and brass mounts give it a solid feel, with an Arca-Swiss compatible tripod foot that lets you mount the adapter itself directly to a tripod. This ensures the lens’s weight doesn’t put additional stress on the camera’s mount.
