The new Fujinon MK 50-135mm zoom has a constant aperture of T2.9 along the whole zoom range. It covers Super35 sensors and provides minimal focus breathing and parafocal behaviour. It’s a lens that rewards those who use it along with the Fujinon MK 18-55mm, since it has the same exact dimensions and this eases workflows –the camera does not need to be balanced after swapping lenses.

The new Fujinon MK 50-135mm T2.9 is a light and compact cine zoom with three independent rings to control aperture, focal length and focus. With a T2.9 constant aperture it delivers a nice bokeh (background defocusing produced by a shallow depth of field) thanks to its 9 aperture blades.
Its image circle covers Super35 16:9 sensors (24.84mm x 13.97mm with 28.5mm diagonal). Besides, its inner low dispersion elements grant good sharpness and it delivers good results working @4K. Its dimensions are equal to those of the Fujinon MK 18-55mm T2.9, which allows for an easier workflow when dealing with stabilizers, gimballs, cranes, jibs,...
The flange distance can be adjusted with a propertary mechanism that allows for back and front focus tuning. In adition it offers a macro switch that provides better magnification and close distance focus –it does not deliver the results that a specifically macro design lense would give but it is surprisingly good.
The focus ring has a rotation angle of 200º and includes standard 0.8 gear, which is also present in the iris and zoom rings –this allows for a seamless usage of follow focus. The fact that its dimensions are the same to those of the MK 18-55mm T2.9 make this combo a great option for ENG or documentary productions.
