The Fujinon MK-R 50-135mm T2.9 Cine Zoom Lens is a lightweight cine-style zoom lens for Canon RF mount cameras with a Super35-sized sensor, mirrorless cinema cameras such as the Canon C70, and cinema cameras such as the RED KOMODO. It features a mechanical design with three independent lens control rings: focus, iris, and zoom. Each ring incorporates a cine-style gear with a 0.8 MOD for interfacing with standard cine-style lens accessories. The focus ring features 200° of rotation, which gives room for precise focus pulls, and the iris is clickless, enabling smooth iris pulls. The lens also incorporates a macro mode for close focusing capabilities.

The lens is color-matched to other Fujinon lenses such as the MK, HK, ZK, and XK series, which enables smooth intercutting between lenses. The 85mm front diameter allows use with many cine-style matte boxes via the use of optional step-up rings (rings not included). The lens weighs only 4.4 pounds, which is light for a cinema zoom that holds focus and aperture throughout the focal length range. It is designed for cameras with a Canon RF mount, so it has a short flange focal distance with only minor vignetting at small apertures between 18 and 20mm, but the lens allows flange focal distance adjustment, so you can fine-tune it to the camera using the lens.
