LEICA SUMMICRON C

The lenses cover an image circle greater than 34mm in diameter which allows you to use the lenses with Super35 sensors and greater - including the RED Epic Dragon sensor in 6K mode. The lenses all maintain the same length and front barrel size (95mm), while the focus and iris gears are in the same position on each lens, speeding lens changes, as you don't need to adjust lens accessories. Mechanically the lenses use a Helix-style focus mechanism and an 8-blade iris and feature opposing focus scales: one for the operator side and one for the assistant side of the lens.
