The Zeiss Supreme Prime 100mm T1.5 lens features an interchangeable PL mount and is marked in feet. The lens produces a 46.3mm image circle, covering full-frame sensors. The internal focus design provides minimal focus breathing and a non-rotating front. The focus ring rotates 300° from a close focus of 45" to infinity, providing plenty of room for precise focus pulls. The iris is made up of 16 blades arranged to create circular, out-of-focus highlights. Both the focus and iris rings incorporate industry standard 0.8 MOD, 32-pitch drive gears, and the lenses within the Supreme lineup share the same gear positions, making for rapid lens changes.
