Offering even greater flexibility by introducing an interchangeable mount, the Zeiss 21/2.9 CP.2 Lens 1868-094 can be used with a broad range of cameras from traditional cine to HDSLR systems. The interchangeable lens mount ensures you do not have to carry multiple adapters when you are traveling. The lens provides a full-frame coverage without vignetting and offers a sweet spot effect with APS-C sensors. The iris of the lens is created from fourteen high-precision blades that are designed to stay round and symmetrical over the entire focal range. This results in a natural and pleasing out-of-focus highlights with a smooth bokeh effect.
