I'm curious about the 85mm focal length in a prime lens. Are those who use it mostly shooting portraits? I've seen many superb photos here on the Cafe shot with an 85mm lens. Since the f/1.4 is a bit out of my budget (unless I felt like saving for a few weeks...which doesn't sound too appealing) how would I be fairing if I picked up one of the 1.8s? Is there an appreciable difference in image quality or is Nikon charging more simply for the larger aperture? Pictures taken with the 85 1.8 and displayed in this thread would be most helpful!
