The Zeiss Compact Prime CP.2 50mm/T1.5 Super Speed EF Mount with Imperial Markings is a fast cine prime lens designed for filmmaking and video production applications. It shoots remarkably well in low-light. Aside from great optics and mechanics, the lens offers broad flexibility in the areas of camera compatibility, follow-focus compatibility, and shooting capacity.

The fast T1.5 does so well in low-light, night and non-bright outdoor environments, that it allows filmmakers to conveniently pursue more creative shots in low-light, especially with high ISO DSLRs and camcorders. The outstanding handle of low-light also serves to limit the need for artificial light and thus allows more mobile filmmaking and delivers more natural-looking scenes. The fast aperture additionally offers more creative possibilities when aiming at a cinematic shallow depth of field.

The optics and mechanics are superior too. The lens incorporates two aspheric lens elements and two special types of glass with abnormal partial dispersion that exceptionally corrects for chromatic aberration. Zeiss-famous T* anti-reflective coating along with internal light traps provide advanced flare suppression. Fourteen high-precision iris blades open up consistently circular across all T-stops, allowing impressive highlights in out-of-focus areas and producing smooth bokeh.
