The Nikon AF-S Nikkor 50mm f/1.4G lens is already $484.95 at B&H (up from $439, it was even $399 at one point). Adorama has the same price, Amazon sells it for $599 (ouch!).
If you need a need a lens, I suggest you buy it asap - try Adorama, Amazon, B&H, Calumet, Ritz or Abe's of Maine - you may still get lucky (use those links to purchase if you want to support NR - same price to you - thanks). As I mentioned in an earlier post, many items may not be available until February 1st when the new prices will be introduced.
