Fujifilm's cinema zoom for Sony FE mount — parfocal T2.9 covering 18-55mm with cine-standard gearing.
The Fujifilm Fujinon MK18-55mm T2.9 is a cinema zoom for Sony E-mount, designed for Super 35 / APS-C image circle cameras rather than full-frame FE bodies. Constant T2.9 maximum aperture throughout the 18-55mm range. The lens is fully manual — no autofocus, no electronic communication — with 0.8M cinema gear pitch on all rings. Parfocal: zoom position does not shift focus. No focus breathing. At approximately 980g and 82mm filter thread.
Cinema zoom with 9 iris blades (circular). 82mm filter thread. Approximately 980g. Minimum focus distance of 0.85m (standard); 0.32-0.38m in macro switch mode. Manual focus ring with 200° rotation. Clickless iris for smooth aperture pulls. Parfocal. No focus breathing. 0.8M gear pitch. No electronic aperture or AF communication. Super 35 / APS-C image circle only. T2.9 maximum aperture.
The MK18-55mm's cinema-specific design differentiates it from photo zoom lenses: parfocal behaviour maintains focus as the zoom ring is adjusted — essential for zoom pulls during recording. No focus breathing keeps subject framing stable when the focus ring is adjusted. The 200° focus rotation enables precise manual focus with gradual transition between distances. The clickless iris enables smooth exposure transitions without audible clicks. These properties are standard expectations for cinema production lenses that photo lenses do not guarantee.
On the used market the Fujinon MK18-55mm T2.9 is available at professional cinema zoom pricing. Condition checks: parfocal function across the zoom range, iris ring smoothness (clickless), focus ring bearing smoothness, 82mm front element for marks, and macro switch operation. Super 35 / APS-C image circle — on Sony FE full-frame bodies, APS-C crop mode is required. No interchangeable mount; Sony E mount specific.
