Fujinon MK50-135mm T2.9 Cine Zoom Lens (E-Mount)
The MK50-135mm T2.9 is the telephoto match to Fujinon's MK18-55mm, built for the same Super 35 / APS-C E-mount cameras and holding a constant T2.9 across the full 50-135mm range. Together the pair covers 18mm to 135mm on one mount system without a stop change between them, which is what a two-camera indie or documentary shoot actually needs from a cine set.
At 980 g and 206mm long it shares the MK18-55mm's compact build, low breathing, and axial-shift control, and its three rings are fully manual with 0.8M gear pitch for standard follow-focus gear. Minimum object distance is slightly longer than its wide-angle sibling at 1.2 m, which is normal for a telephoto zoom of this reach.
