This one’s just for show and not for everybody else like you and me. Carl Zeiss is exhibiting a humongous 1700mm telephoto lens at this year’s Photokina tradeshow which kicks off September 29th in Cologne, Germany.
Dubbed the STL Sonnar, the telephoto lens weighs 256 kg, has a focal length of 1700mm, f/4 speed and 21x magnification. It appears to be custom-built for a client who will be using it on the very high-end Hasselblad 203 FE with a 6 x 6 medium format film.
Check out Hall 2.1, Booth B010 if you happen to be at the Photokina convention during those days. The STL Sonnar will be there.
