Contax 28mm f/2.8 Carl Zeiss Biogon T* Lens For Contax G System {46} Description


The Contax 28mm f/2.8 Carl Zeiss Biogon T* is a highly corrected autofocus rangefinder lens for the Contax G1 and G2 cameras.  When mounting the Contax 28mm G users immediately notice most of the lens fits inside the camera body; it's a highly corrected optical design that is externally compact.

Unburdened by a mirrorbox and flange focal distance constraints this 7 element 5 group Zeiss Biogon T* multi-coated design is almost perfectly corrected for distortion.  Sharpness, contrast, color reproduction and bokeh are all superb by any standard.

The bright f/2.8 maximum aperture aids shooting in available light and with beautiful titanium metal construction keeping weight to a remarkable 150g (5.3oz) the lens is incredibly easy to hand hold and carry.

The 28mm G offers an unusual combination: noticeably superior image quality of a top tier rangefinder optic coupled with easier and faster focusing via autofocus as well as auto exposure; the results are compelling capabilities for photojournalism.  The popular 28mm focal length and it's 75° angle of view are perfect for applications from landscapes to street photography.
