The Contax 45mm f/2.8 T* is a bright auto focus wide-angle lens designed for the Contax 645 mount system; it's an excellent lens for architecture, landscapes, street photography, and much more.

The Contax 45mm offers a high-speed f/2.8 aperture allowing for bright viewing, even when shooting in dim light.  The solid, all-metal design, including the focus ring (rubber coated), aperture ring, mounts, and threads provides you with the no-compromise high-end craftsmanship you expect from a top of the line lens.  The lens features an internal focus design coupled to a built-in AF motor that's responsive and quiet.  If ever needed, the Contax 645 system allows easy manual focus touch-up while the body is set to Single AF mode.

The Zeiss Distagon 45mm f/2.8 produces crisp clean images with edge to edge sharpness.  Legendary Zeiss T* coating delivers superb contrast and precise color delivery.  Distortion in the Distagon T* 45mm lens is remarkably low.  Wide open, you can expect a lens perfect for dreamy wide images with unmatched bokeh.
