Lens OverviewContax AF 80mm f/2 Carl Zeiss Planar T*

The Contax AF 80mm f/2 Carl Zeiss Planar T* is a prime lens built exclusively for the Contax 645 medium format camera system. With a fixed focal length of 80mm and a maximum aperture of f/2, this lens sits squarely in the standard focal length range for medium format photography, making it a natural choice for portrait, editorial, and studio work where a natural perspective and generous light-gathering ability are priorities. The f/2 maximum aperture is notably fast for a medium format prime, giving photographers meaningful control over depth of field and the ability to shoot in lower ambient light conditions.

Autofocus is supported alongside manual focus operation, offering flexibility depending on the shooting situation. The lens accepts 72mm filters, which is worth noting for photographers who use polarizers, ND filters, or other accessories. Weighing 780g, this is a substantive piece of glass that reflects the build standards expected of medium format optics.

It is designed solely for the Contax 645 mount, so compatibility is straightforward — this lens is purpose-built for that system and not intended for adaptation to other camera platforms. For photographers already invested in the Contax 645 system, the 80mm f/2 represents the standard focal length option in the lineup.
