Presenting an ultra-wide field of view, the Canon EF-mount Distagon T* 15mm f/2.8 ZE from ZEISS is a unique prime that is ideal for landscape, interior, and astrophotography applications. Its relatively bright f/2.8 maximum aperture is suitable for working in difficult lighting conditions while shooting handheld. A Distagon optical concept is used, which helps to reduce field curvature and distortion for high overall sharpness and accurate rendering across the frame. Also, a T* anti-reflective coating has been applied to individual elements, and a lens hood is integrated into the lens's design, to control lens flare and ghosting.
