This custom made Leica lens will cost you a cool $2 million. It even has its own custom fitted four wheel drive Mercedes-Benz to lug it around. Commissioned by Prince Saud bin Muhammaed Al Thani from Qatar, this is a Leica APO-Telyt-R 1:5.6/1600mm. It measures four feet long and weighs 132 pounds. And as you guess, you can just put this in a camera bag.
As to what it's going to be used for, we're not sure. Either way, at $2.8 million this is one heck of an expensive lens.
