Bought the legendary Zeiss 21mm

I was torn between the Zeiss 21mm and the new 35mm f1.4. Then I decided on the 21mm since I already owned the 35mm f2. The f1.4 can wait. The Zeiss 21mm is a legendary lens. It was originally designed for the Contax camera (not exist any more) and had been craved by the Nikon/Canon users for a long time. (Thanks for Contax's out of business, Zeiss had to adapt it for Nikon and Canon mounts.) With the D5100 and Zeiss 21mm coming, my camera bag will be crowded next weekend.
