Leica Leitz Summicron-C's 6 lens set 

18mm, 25mm, 32mm, 50mm, 75mm and 100mm at T2.0. 

The lenses feature stainless steel PL mounts, which make the lenses compatible with the most commonly used professional digital cinema cameras, including the ARRI Alexa, RED Epic, Sony F5 and F55, and Canon C300 PL. They cover a large image circle, over 34mm diameter, allowing you to use these lenses on the RED Dragon sensor in 6K mode. They feature an image circle of over 34mm, which easily covers the Super-35mm format, as well as covering the larger RED Epic Dragon sensor in 6K mode. The lenses feature similar characteristics as the larger, faster, and significantly more expensive Leica Summilux-C lenses. However, the Summicron-C lenses are one stop slower at T 2.0 and are 30% shorter and 20% lighter than the bigger lenses.

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.
