What do I like about the D700 and the Nikon 50mm F1.4 AF-D combo? They make up a very useful natural low light combination that is great for on location portraits, maintaining some sense of the surroundings. It also provides closer interaction with the subject for better communication and feedback with the photographer. Many people think that the 50mm focal length is a boring lens, but for me, I feel it closest replicates the eye and hence is the most honest of the lens without distorting reality for dramatic effects. A very general purpose lens that can give stunning results under the right hands. Lens are tools to be used like the brushes of the artist on a canvas anyway.
