Distagon T* 18mm f/3.5 ZF.2 for Nikon
Ultra wide angle manual focus prime lens
The Zeiss Distagon T* 18mm f/3.5 ZF.2 Lens for Nikon F-mount Cameras is an ultra-wide manual focus prime lens that provides excellent image performance over its entire image range from 0.3 m to infinity. When mounted to a digital SLR using a DX-type sensor, it has an effective focal length of 27mm (35mm equivalent). It features Zeiss T* anti-reflective coating to produce beautiful pictures even under difficult lighting conditions.
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.
