The Zeiss 21mm T/2.9 CP.2 Compact Prime Cine Lens with E Mount is a 21mm fixed focal length lens with a flexible design so that it can be used on both cinema and DSLR cameras. An interchangeable mount for PL, EF, F, E and MFT mounts allows you to use the cine lens with movie cameras and HDSLR cameras. The lens supports full-frame coverage (24 x 36mm), and is suitable for HDSLRs with APS-C format sensors. Featuring 14 high-precision blades, which create a consistently round and symmetrical iris opening over the entire T-stop range, the lens ensures enhanced out-of-focus highlights and a smooth bokeh. T* Anti-reflex coating and internal light traps help suppress disturbing flares. The Compact Prime Cine Lens features a unique lens design that helps provide enhanced contrast, resolution and color rendition, and reduces distortion. Markings for distance are given in feet.
