Mitakon Speedmaster 25mm T1.0 Micro Four Thirds Cine Lens

The Speedmaster 25mm is the normal-length prime in Zhong Yi Optics' T1.0 Micro Four Thirds set, and it carries the same fast-glass logic as its wider sibling: a T1.0 stop that keeps a scene exposed in near-dark rooms and separates a subject from its background more aggressively than any T2.8 zoom can. Eleven elements in eight groups sit behind a 9-blade iris running T1.0 to T16, with a 77mm front filter thread shared across the MFT line.

Focus turns a 151 degree throw for fine, repeatable marks, and the aperture ring has its own 60 degree throw so an operator can pull either one smoothly during a take. Minimum focus is 0.25m, and at 535g it stays light enough for a gimbal rig or a small MFT cinema body. As with the rest of the set, the aperture control is stepless and silent, so exposure can shift mid-shot without an audible click.
