The Zeiss Distagon T* 15mm f/2.8 Lens for Canon EF Mount & Nikon F Mount  is a precision ultra wide-angle lens built with a Carl Zeiss T* anti-reflection coating that yields images with depth, contrast, and brilliance even under difficult lighting situations. It also delivers photos with contrasting edges, without color fringing. This manual focus ultra wide-angle provides the photographer with a tool that enables dramatic perspectives and creative possibilities. It's useful for landscape photography, interiors and other subjects that require its unique spatial organization. It focuses to 9.84" (24.99 cm).

All existing exposure programs (P, AV, TV, M) and the AF confirmation function of the camera are supported; lens information (focal length and speed) is passed on to the camera. Certain functions that require the use of AF lenses (various scene modes, A-DEP) are partially unavailable.  It has a M95 x 1.0 size filter thread and a built-in lens shade.
