Giving an impressive wide-angle field of view along with bright performance, the Canon EF-mount Distagon T* 25mm f/2 ZE from ZEISS is a flexible prime well-suited for a range of subjects, from landscapes to architectural shooting. The lens uses a Distagon optical concept, which helps to reduce field curvature and distortion for high overall sharpness and accurate rendering across the frame. One aspherical element and four anomalous partial dispersion elements are featured, too, which help to suppress distortion and color fringing in order to promote more accurate rendering. A T* anti-reflective coating has been applied to individual elements to control lens flare and ghosting. Additionally, further contributing to high sharpness and clarity, a floating elements system is used to achieve consistent, well-controlled image quality throughout the focusing range.
