Don't sweat it over the cost of the 400 f/2.8isII. This one checks out at over $2 million.http://www.petapixel.com/2012/08/27/the-worlds-most-expensive-camera-lens/#more-70978Of course, it's a Leica...-PW
If I had that lens I could stay between the football stadium and soccer field and shoot both games from the same location
Hubble would have to be near the top of the list, too. At $2.5b to construct, then all of the maintenane and the big upgrade a couple of years ago, I think it has cost almost $7b. But it does get some spectacular shots.
Personally I don't understand how a Leica APO-Telyt-R 1:5.6/1600mm would be worth 2.79 million dollars. Thats really in WTF territory for me. Unless all the glass is sapphire crystal or something ridiculous.
