Based on Zeiss ZF.2 optics, the PRIME CIRCLE XM 35mm f/1.4 SuperSpeed Lens from LockCircle covers full-frame sensors with a cinema-style housing, featuring expanded focus markings for accurate focus control. The SuperSpeed designation refers to the f/1.4 maximum aperture and is a carryover from the original Zeiss designation. The lens sports manual focus and iris and incorporates a Canon EF (EOS) mount, which can be swapped out for a Nikon F mount (not included).
This rehousing of the ZF.2 still lens creates a cinema-style lens complete with dual focus scales, one on each side of the lens, and adds a cinema-style geared focus ring. The lens itself has a maximum diameter of 97mm with a front outer diameter of 95mm, making it compatible with many matte boxes. Each lens in the PRIME CIRCLE XM series features a 95mm diameter front for quick lens swaps.
