No kidding and it must be crazy....A telephoto lens weighing 256 kg (564 pounds) ,weighs almost more than two or three average men.
And just imagine how to transport the lens to shoot wild life in the jungle.
Zeiss announced that they have created the world’s largest telephoto lens, a 1700mm f/4 . It was developed for long-distance wildlife photography.
Never before has the world of photography seen such a lens. This supertele lens provides 21x magnification. In search of the highest imaginable image quality the client decided for 6x6 medium format and the Hasselblad 203 FE as the best camera he is aware of.
At 1700 mm focal length and a speed of f/4 this lens put requirements on optical glass, lens assembly and quality assurance methods, never before encountered in photo lens manufacture.
This 256 kg behemoth also required Carl Zeiss to develop totally new ways of operating a telephoto lens, including servo controlled aiming and focusing.
Drawing from its expertise in satellite and space optics as well as semiconductor fabrication lenses Carl Zeiss was happy to accept the challenge.
I wonder how good the image quality is? And how much this custom-made lens cost
