DZO Pictor Zoom 20-55mm T2.8

FULL DESCRIPTION

The DZO Pictor Zoom 20-55mm T2.8 is a cine-class parfocal zoom lens for Super35 format. Designed to keep focus while changing focal length, it delivers a constant T2.8 aperture and a smooth, cinematic rendering suited to narrative, documentary, and dynamic productions.

Its floating-optics construction minimizes focus breathing, helping maintain framing consistency during focus pulls. Interchangeable PL and EF mounts broaden camera compatibility, and 0.8 MOD geared rings for focus, zoom, and iris ensure seamless integration with follow-focus units, zoom motors, and remote systems.

Aimed at professionals and serious filmmakers, the Pictor 20-55mm is a versatile workhorse when optical flexibility, cinematic look, and robust build are required without swapping primes mid-shoot.
