Released in 2007, the 14-24mm f/2.8 AF-S is a full-frame lens designed as a wide-angle companion to the D3. Demand was so strong for the lens that Nikon implemented a pro-first policy that required (among other things) that the lens was only available if you purchased a D3. This policy has since been lifted, making individual purchase of the lens possible.
The 14-24mm f/2.8 is packed with some of the newest lens technology Nikon has to offer, including a revolutionary large-diameter Precision Glass Molding (PGM) element to eliminate coma, and a Nano Crystal lens coating to ''ensure superior color balance and reproduction.''
