Zeiss Hologon 8/16mm T*

Using the traditional Hologon® ultra-wide-angle lens as a basis, Carl Zeiss has designed a 16 mm Hologon® f/8 lens. This interchangeable wide-angle lens is virtually distortion-free and provides superior image quality. In view of the extreme field angle, a loss in brightness towards the image edges is inevitable. For this reason, a gradation filter 4x is available to eliminate this effect.

The short focal length of 16 mm and the fixed aperture of f/8 of the Hologon® T* lens allow photography using the fix-focus setting. The wide field angle of this lens opens up interesting perspectives to the Contax G photographer: whether it is architectural, advertising, fashion or landscape photography, pictures taken with this lens will always capture the viewer's attention.
