Fujifilm Fujinon MKX18-55mm T2.9 Cine Lens (X-Mount)

The FUJINON MKX18-55mm T2.9 is a cinema zoom built for Super 35 X-mount bodies, holding a constant T2.9 aperture across the whole 18-55mm range so exposure does not shift as you zoom. It brings the optical discipline of Fujinon's broadcast and cine glass, low breathing, minimal distortion, and even resolution to the corners, to Fujifilm's mirrorless cinema line.

Built for hands-on cinematography, it has separate, geared rings for focus, zoom, and iris with consistent 0.8M gear pitch for follow-focus and matte-box rigs, and electronic contacts pass lens data to the camera. The front diameter is a standard 85mm and it takes 82mm screw-in filters, with a minimum object distance of 0.38m at the wide end.
