Fujifilm Fujinon MKX50-135mm T2.9 Cine Lens (X-Mount)

The FUJINON MKX50-135mm T2.9 is the telephoto half of Fujifilm's native X-mount cine pair, covering 50-135mm at a constant T2.9. Matched to the MKX18-55 in size, gear positions, and front diameter, it lets a camera team swap between the two without re-rigging the follow focus or matte box, which keeps a Super 35 X-mount build fast on set.

Like its wider sibling it is engineered for controlled focus breathing and even sharpness across the frame, with separate geared focus, zoom, and iris rings at 0.8M pitch and electronic contacts for lens metadata. The front is 85mm with an 82mm filter thread, and minimum object distance is 0.85m at the wide end.
