DZOFilm Catta Zoom 2-Lens Kit (18-35/35-80 T2.9) Black Sony E Mount (FF)

Only one lens change separates an 18 mm establishing shot from an 80 mm close-up with the DZOFilm Catta Zoom 2-Lens Kit (18-35/35-80 T2.9) Black Sony E Mount, and it falls at 35 mm, the one focal length both zooms share. Each is a full-frame cine zoom with a 43.5 mm image circle, held at T2.9 throughout, so neither the swap nor a live zoom shifts the exposure.

Take a conference filmed from 5 m. At 18 mm the wide camera holds roughly 10 m of stage; a second body on the 35-80 goes from a 5 m two-shot to a single speaker in medium shot, about 2.25 m across, at 80 mm. The lenses are parfocal, so that push-in can go out live once each zoom is shimmed to its camera. Breathing is held low: a rack from the speaker to a raised hand in the audience leaves the frame edges in place. Focus reaches 0.51 m (18-35) and 0.74 m (35-80) from the sensor, enough for a cutaway of notes on the lectern.

The pair is matched in more than name. With 20 elements in 14 groups (wide) and 20 in 15 (standard), the two keep colour near neutral and skin natural, so cutting between them asks little of the grade. Sixteen iris blades keep defocused stage lights round. DZOFilm builds both on one mechanical platform: focus rotates 270°, zoom 100°, iris 77° or 75°, with 0.8 MOD gears on all three rings. On a rig with wireless FIZ motors, a swap means re-engaging them, not moving rods and brackets. Neither zoom has electronic contacts, which only matters if a VFX team expects lens metadata.

Filters carry over too: one clamp-on matte box fits both 80 mm fronts, one screw-in ND or polariser both M77 threads. A rear slot takes Catta COIN add-ons (ND, Black Mist, streak and star), sparing a stack of glass on the front at 18 mm, where corners can darken. PC+GF composite barrels stay manageable on a shoulder rig or gimbal. On a Sony E mount body such as the FX2, the kit fits directly, and the bayonet changes by hand to RF, L, X or Z, sold separately. Shims, support bases with rods, caps and a foam-cut hard case are supplied, so a production company covers 18 to 80 mm with one matte box, one filter size and one case. A Catta 70-135 on the same front and gears can join later to reach 135 mm.
