Effectively equivalent to the traditional 50mm 1.8 lens that was the traditional "normal" prime in the days when 35mm film ruled, the sub-$200 Nikon 35mm f/1.8G AF-S DX Lens for Nikon Digital SLR Cameras
will arrive in March and be half as expensive as the Sigma 30mm f/1.4 EX DC HSM Lens
. It will also be significantly lighter and smaller. At that price point, if the optical quality is anywhere in the ballpark of Nikon's 50mm primes, this lens is going to fly off the shelf and be a standard part of the kit for any Nikon DX-system photographer. I know I'm going over to the B&H site right now to see if I can pre-order it. Nikon did a nice job on this one listening to the demand from the street - I'm not sure a lot of people expected to see them releasing prime lenses for the DX format.
