1700mm, 256kg. That’d be the Zeiss Apo Sonnar T* 4/1700. Oh my goodness gracious.

That's quite a lens. I'm reminded, though, of Mike Johnston's "Uses and Applications of 35mm lenses." http://photo.net/mjohnston/column57/

"1200mm: no known uses"

Okay, yes, if I'm doing my calculations correctly, this 1400mm lens would have the coverage of a 700 on a 35mm camera, but then I suppose the real limitations of this wonder of lens-grinding are its price and size.

This is offtopic, but...

Commenting doesn't work in IE (specifically IE6 in XP SP2). There's some kind of javascript error. And with javascript disabled your site is somewhat mysterious; comments appear but there seems to be no way of posting them.

That thing is a torpedo! Is it used for doing macro photos of ants three miles away?

They don't say a word about the tripod, or whatever carries it.

Since it's designed for taking wildlife photography, it must be mounted on a vehicle. But you cannot drive when the lens is mounted because of the shaking and vibrations, so it must be kept in a box and then mounted before taking the photos. Hence, a need for a small crane or something.

Life is too complicated!

Silly size of lens, but quite a reasonable telescope. Actually, the difference between a camera lens and a normal refracting telescope (without the eyepiece) is more a matter of mind-set than optics.
