Parfocal workflow
Focus is maintained when changing the focal length. Ideal for smooth zoom shots and for quickly readjusting the composition on a rig.
The DZOFilm Catta Ace FF 18–35 mm T2.9 Black is a parfocal cine zoom lens designed for full-frame sensors. It complements the Catta Ace 35–80 and 70–135 mm lenses with a wide 18–35 mm range, while maintaining a constant T2.9 aperture for smooth zooming within a single shot.

The aluminum body, featuring fiberglass and polycarbonate components, keeps the lens lightweight for use on a rig or with a stabilizer. Manual focus has a 270° rotation, the aperture features 16 blades, and the interchangeable mount system supports PL, EF, and LPL configurations.

A wide-angle full-frame cine zoom with a constant T2.9 aperture. Its 18–35mm range, parfocal design and 0.51m minimum focus help keep a shot under control while reframing.

This official production frame shows the Catta Ace 18–35 mm on a cine rig outdoors. Its wide range and compact cine mechanics leave room to reframe without changing lenses.
An official sample frame from DZOFILM’s Catta Ace 18–35 mm materials. The 0.51 m minimum focus distance is useful when working close to a subject.


A second official example from the same project brings together natural light and detail. It is visual inspiration, not a laboratory test.
An 18–35 mm range for full-frame cine work, allowing you to change the angle of view without refocusing. The lens maintains a T2.9 aperture throughout the entire zoom range.
