Mitakon Speedmaster 50mm T1.0 Cine Lens, PL Mount

This is the Arri PL mount version of Zhong Yi Optics' 50mm T1.0, the same optical formula as the Canon EF version but built onto a PL flange for camera systems and rental houses standardized on PL glass. Twelve elements in six groups sit behind a 9-blade iris running T1.0 to T16, with a 105mm front filter thread and a 45 degree angle of view.

Minimum focus is 0.65m with a 0.1x maximum reproduction ratio. The iris is stepless and silent for pulls mid-take, and focus breathing is kept low across the range. At 114mm in diameter, 136mm long, and 1,800g, it matches the EF version's size and handling, so a production running both mounts across different bodies gets the same T1.0 look and the same operating feel from either.
