The Zeiss Distagon T* 21mm f/2.8 ZF.2 Lens for Nikon F-Mount cameras is a manual focus professional lens distinguished by having exceptional color control which allows for breathtaking high contrast pictures without any color fringes. Thanks to the legendary Carl Zeiss T * anti-reflection coating, the Distagon T* 21mm f/2.8 delivers outstanding results. Its wide aperture delivers fantastic performance for both daylight and in lowlight shooting. This lens is equipped with an F bayonet (Nikon) lens mount, and is ideal for landscape, architecture, portrait, group, and commercial photography.
The new ZF.2 lenses are an enhanced version of ZF lenses. They feature an electronic interface (CPU) that enables support of all important camera operating modes such as shutter priority, aperture priority and programmed auto exposure or manual exposure settings. Photographers no longer have to set the parameters in the camera menu as the lens now transmits standard data such as focal length, speed and the aperture setting to the camera. This data can then be viewed in the EXIF data of each picture.
The ZF.2 lenses have a mechanical lock on the aperture ring to lock the aperture ring at the lowest setting and prevent unintentional adjustment while taking pictures.
For technical reasons, these lenses do not have a half-step aperture lock between the lowest (stop position) and the second lowest aperture setting. This guarantees reliable recognition of the automatic position. The lowest aperture on ZF.2 lenses is colored orange to emphasize the automatic position of the aperture ring.
