Hasselblad Zeiss Tele-Tessar f/8 500mm

This is the genuine tele lens consisting of a collective front component and a dispersive rear component separated by a larger air space.
Compare with its focal length the lens is short. The weight of approx. 2kg allows hand held exposure. 
Even at full aperture the lens offers optimum image quality. The tele tessar f/8 500 mm is preferably used for long range work (landscape photography and photography of animals in their natural habitats). Other applications are sports and press photography when there are large distances between obeject and camera.
