Hi all. Great forum here, and I intend to be a regular lurker, if not regular contributor. I've had two great gifts this year, one a Nikon D80, the other an incredibly gorgeous baby boy (not necessarily in that order). I'm putting together a Christmas list and would like to finish the year with 50mm lens. I'm hoping for the Nikkor f/1.4D (although the f/1.8 might be more affordable). What sort of improvements to the following shots can I expect with such a lens? These were taken in low light around 1/30 - 1/60 sec at F3.5 with the Nikkor 18-135mm AF-S. They seem a little grainy and depth of field could be a bit more dramatic, among other things. 1. 2.
