The 300 mm Tele-Tessar

®

 T

* f/4 lens offers a long 

focal length, remarkably high speed, compact 
design and easy operation at one and the same 
time. It is a telephoto design where the distance 
between the front lens vertex and the rear focus is 
only about 80% of the focal length. It offers 
virtually perfect monochromatic correction and 
excellent image quality even at full aperture - a 
decisive improvement over earlier telephoto 
designs. 
It is, however, the mechanical construction of the 
lens that allows full utilization of its superb optical 
performance. The lens is easy to handle despite its 
long focal length, and the favourable 
opto-mechanical transmission ratio of the focusing 
helicoid offers the 

photographer more flexibility. The lens hood which 
is connected with the outer barrel can be pushed 
back for transport. For shooting from a tripod, the 
lens has a tripod socket positioned approximately at 
the centre of gravity of the lens-camera 
combination. The camera can be swung through 
90% for the transition from horizontal to vertical 
shots. 

This Tele-Tessar

®

 lens is ideal for large-size pictures 

of distant subjects and for photographing at long 
distances without being observed. The relatively 
long focal length makes the main subject stand out 
distinctly against the background, an effect often 
required by photographers.
