I shoot an 18-135, 3.5-5.6 lens for portrait because of economic reasons. I went for the D200 body and a 70-200 2.8 first, over the portrait glass. So... I am ready to buy a good portrait lens. I think I need a prime over the 17-55 2.8 that I really have my eye on but I honestly can't decide on which one. I wanted to know from you portrait people out there if you could only take 1 lens on a portrait shoot (1 to 3 people in the frame) would you grab the "nifty 50" or go for the 85mm? I am talking primes here not short range zooms.
