DZOFilm Pictor Zoom 20–55mm T2.8 Black PL & EF Mount (S35) is a parfocal cine zoom covering the Super 35 format with a constant T2.8 aperture. It keeps critical focus throughout the entire 2.75× range, shows minimal focus breathing, and renders round highlights via a 16-blade iris. An internal floating focus group stabilizes the image while racking, delivering consistent contrast and resolution across the frame.
With an image circle of φ31.5 mm, the lens fully covers mainstream S35 cinema and broadcast sensors. The supplied PL and EF mounts are user-interchangeable, with shimmed back-focus for precise flange calibration. Close focus is 0.60 m (2.0 ft), enabling tight inserts and handheld detail shots. Cine-standard 0.8 MOD gears on focus, iris and zoom interface cleanly with FIZ systems, follow-focus units and wireless motors used in OB vans, gimbal rigs and studio pedestals. In EF setup it matches EF-mount cinema bodies (e.g., Blackmagic) but not EF DSLRs. Mirror clearance limits use 4K
The optical path targets neutral color, low distortion and controlled veiling flare to produce a clean S35 look that grades predictably for television, commercials and fast-turnaround news magazine pieces. The aperture spans T2.8 to T22 for exposure discipline from interiors to exteriors, while a long focus throw supports accurate pulls at minimum distance. Mechanics are fully manual with no electronic protocols for repeatable performance on dollies, sliders and shoulder rigs.
Standardizing on the Pictor family streamlines crews and accessories: the 20–55 pairs naturally with the 50–125 to cover wide through medium-tele without gaps. Keep scale positions consistent across setups and maintain focus during live zooms. For productions needing a compact, reliable S35 zoom, choose the DZOFilm Pictor Zoom 20–55mm T2.8 for narrative, documentary, broadcast, corporate and streaming pipelines.
