Zeiss 21mm f 2.8 T* Distagon
Super Wide Angle LensThe legendary Distagon T* 2.8/21 is now being introduced for SLR cameras with EF, F and K bayonets. Thanks to its excellent performance, this modernized version from the former Contax system sets new standards in this focal length class. “The outstanding correction of chromatic aberration enables photos without color fringes even in high-contrast light conditions”, says Martin Klottig, Marketing Manager, Carl Zeiss Camera Lens Division. “Even at full aperture, the floating element design ensures optimum edge-to-edge image quality over the entire focusing range. And even in difficult light conditions, the new Distagon provides excellent results thanks to its T* coating, optimum reflection reduction and exceptional chromatic correction.”
The shortest possible distance setting of only 0.22 m makes the lens ideal for impressive perspectives. Typical applications include architectural, journalistic and landscape photography. The Distagon 2.8/21 is available with an EF bayonet (ZE), F bayonet (ZF) and a K bayonet (ZK). It is suitable for both digital and analog full-format SLR cameras.
