There is a story on Gizmodo about the third Nikon ever built selling at auction for a ton of money. I went to the auction page to drool and found something interesting.
I just got this lens for my birthday. Mine is three or four years newer, but is exactly the same as this one; and is in near mint condition. It did not cost $576.
So, either we got an amazing deal on mine, or some poor sap just got ripped off at this auction.
Either way, hooray for me!
