Additional information:
The Carl Zeiss Distagon 45 mm f/ 2.8 C645 is a wide-angle AF medium format lens for the Contax 645 system.
The angle of view of a 45 mm medium format lens corresponds to the same angle of view of a 28 mm on a 35 mm system.
The lens uses an internal focusing.
The Carl Zeiss Distagon 45/2.8 C645 lens has a slight vignetting, which is good for photographers, who want to see the same brightness of a blue sky across the frame on landscape photos.
The lens distortion has been minimized due to the special Carl Zeiss retrofocus lens design (classic retrofocus lens suffers from distortion and vignetting through its strongly asymmetric design and a large negative front element (lens)). PDF Files: Posted by: kenjiz Date of publication: 12.04.2012
