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 degrees 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.
