The Zeiss Sonnar T* 4/1700 weighs about 564 lbs. and there is one buyer so far. An action photographer's wet dream perhaps?

I thought I read abou some 300 kg like 1800mm Canon? I know canon has the 1200mm. I also remember reading about this one I think, but not sure.

Too bad it's for a Hasselblad...JK

. Great cameras, just hideously ugly.

I don't believe Canon makes an 1800mm telephoto. Canon did make a 2000mm and a 5200mm "TV" lens way back when, but the 5200 weighed in at 100kg. The Zeiss weighs 265kg. Nikkor made a 1200-1700mm zoom, along with the infamous, telescope like 2000mm Reflex from the '70s. The Reflex only weighed in at a measly 17.5kg though.

Edit: It should probably be known that the Canon and Nikkor lenses above are "Mirror" lenses, which differ from actual telephotos in design, but produce relatively similar results.

Oh well, whatever. Not that it really matters, none of us would ever get to us one. Would be cool for astronomy maybe.

The aperture on these things though really are quite amusing for their focal lengths. :\.

Yes, because of this you end up using something like a ten second exposure, not very practical for most purposes.

eh?

as far as i can tell this thing has a F4 rating. crack on a 400 or 800 ISO and good sunlight and youll be getting a 1/1000th exp quite easily. remembering, a great deal of super long work is done in good sunlight, although 1800mm is starting to get silly. the canon 600/4 is already probably overkill, the 400/2.8 is the one to get.

The old 1200-1700mm Nikkors at F5.6 used to require shutter speeds of almost a full second if the lighting wasn't ridiculously bright. Keep in mind that this is for film, not digital.

Jesus christ.

I can't even imagine how expensive it must be.

Umm? Dude, I don't think you'de use this for sports photography or something where your trying to "freeze" motion because you would probably not be travelling with a lens this size much.

And at almost 600 pounds, I'm certain you would have it on a tripod, in which case a 10 second shutter speed wouldn't really matter all that. For the amount of time needed to probably get ahold of one of these things, waiting 10 seconds to get a shot I'm sure wouldn't kill anybody. I use slow shutter speeds all the time in my room because I don't shoot stuff in motion and well, my room has sh1t lighting, even at ISO 3200 your using damn slow shutter speeds. I found a tripod can easily fix this.
