500mm lens hands-on by Engadget.

Engadget (Click here) visited the CP+ show in Japan and played with the new Sony 500mm f/4.0 lens: “The lens focused surprisingly quickly, especially given its massive 500mm fixed focal length. Moving from subject to subject at varying distances, we were typically able to achieve focus in a fraction of a second. Long lenses have traditionally been tricky on the focus front, but this guy handled it like a champ”

The lens costs 13.000 Euro (no preorders yet) and is the most expensive Sony lens ever made. It beats the 300mm f/2.8 APO G SSM Autofocus Lens which costs $3200 at Bhphoto (Click here).

Curiosity: The most expensive lenses are from leica. Look at that Prototype 50 Summicron which sells for more than $35000 on [shoplink 11445 ebay]eBay (Click here)[/shoplink]!!!
