MK50-135mm T2.9 RF Mount

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.

T2.9 to T22 aperture with nine iris blades for attractive bokeh
The 28.5mm diameter image circle covers the 3-perf Super35 format with a 16:9 aspect ratio
Industry-standard 0.8 film pitch gears for focus, zoom, and iris control
The gear ring positions for focus, zoom, and iris are located at the same position on lenses in the MK and MK-R series, making switching between the zooms quick as you don't have to adjust the position of lens accessories
Lenses in the MK-R series have the same weight and length, so there is no need to rebalance your camera when you change from one lens to the other
200° focus barrel rotation
No shims are required to adjust the flange focal distance as this lens has a built-in adjustment mechanism
Macro focus function available
