http://petapixel.com/2012/04/23/nikkor-1200-1700mm-the-mother-of-all-super-telephoto-nikon-lenses/ Time to put this on your Christmas list! A Nikkor 1200-1700mm lens weighing over 36 lbs.!
I hope the focus and zoom rings are near the camera end. :D
Imagine trying to shoot a car race while zoomed to 1700mm. The article didn't mention what size filter it takes. I bet the case would cost more than most lenses. And how about a tripod? I'm not even going to bother looking on ebay for one.
I'd need to check another bag to Africa just for this lens and its accessories. I guess that would be a small price to pay if you can afford the lens in the first place. ..
See? Some people just don't know how to list things on ebay. If you start with a high price, you tend to get no bids. He should have started at $0.99, which is what I always do. :D
