Arri PL

Arri PL ( PL for engl. Positive lock) is a lens mount system used for 16 mm, 35 mm and digital cinema cameras.

The port was developed by ARRI in 1980 as the successor to the previous one, introduced in 1965 bayonet lock, but is not compatible with older lens ports Arri, because it has a larger diameter. Older Arri port systems can be connected with an adapter to PL.
