The Fujinon MK18-55mm T2.9 covers a wide-to-normal range in Sony E mount, for Super 35mm-sensor cameras — a run-and-gun and documentary staple where a single lens needs to carry a shoot from establishing wides to conversational mid shots without a lens change, keeping a crew light and fast to reset between set-ups on a tight-turnaround day.

Cine mechanics on an E-mount body

The lens keeps a constant T2.9 aperture through the whole 18-55mm range, and its three control rings — focus, iris and zoom — are independent and each geared to a standard 0.8 MOD, so it takes the same follow-focus and zoom-control gear as larger cine primes and zooms rather than needing E-mount-specific accessories built for stills lenses.

Focus and iris control

A clickless 9-blade iris allows smooth iris pulls rather than stepped stops, the focus ring turns through approximately 200° of rotation for fine manual adjustment with room between marks, and a built-in macro mode extends the close-focus range for detail shots without swapping to a separate lens.

Cuts cleanly with the rest of the MK line

Colour is matched to Fujinon's HK, ZK and XK lens series, so shots from this lens intercut with those series without a separate colour-matching grade pass — useful when this wider MK zoom needs to sit alongside longer, higher-tier Fujinon glass on the same production, or when a second camera runs a different focal range on the same set-up.

Weight and mount adjustment

85mm front outside diameter, 2.16 lb, with flange focal distance adjustment built into the mount for back-focus calibration — light enough for gimbal and handheld set-ups as well as a conventional cine rig.
