Description — Fujifilm MKX 50-135mm T2.9
The Fujifilm Fujinon MKX 50-135mm T2.9 is a cine-type zoom lens built for the Fujifilm X mount, covering a 50mm to 135mm telephoto focal length range with a constant T2.9 aperture. Designed for Super 35 format capture in cinema and video applications, this lens is a manual focus instrument — there is no autofocus — giving focus pullers the direct, repeatable control that professional productions demand. The constant T2.9 T-stop is a true light transmission measurement, ensuring that exposure remains predictable and consistent at every point in the zoom range.
An 82mm filter thread at the front provides a standard interface for matte boxes and filter systems commonly used in cine workflows. Weighing 980g, the lens strikes a balance between optical capability and physical manageability, making it a viable option for gimbal rigs, shoulder mounts, and handheld rigs where weight distribution is a key consideration. Note that no image stabilization is included, so stable footage depends on the support system used.
