Design and Features
By using special glasses in this 800 mm Tele-Apotessar T* f/8 lens it was possible to achieve almost perfect correction of chromatic aberration. The lens provides excellent image quality throughout the entire focusing range from infinity to 4 m. For focusing, two elements inside the lens are moved. The advantage of this internal focusing is good constancy of the center of gravity during focusing. Adjustable stops permit the preselection of two ranges, which is helpful in fast focusing.
The lens has a tripod socket. For changing from oblong to vertical format, lens and camera can be rotated around the lens axis after slackening a clamp screw.
