So, lately I've been getting a lot of inquiries in portrait and modeling work. However my equipment has been geared toward nightclub settings so my *huge* arsenal of 2 lenses are for that purpose only. I am shooting with a D200 with 18-55mm f/3.5-5.6 and 17-70mm f/2.8-4.5 Would anyone advise on a particular focal range for portrait and modeling work? Also, would prime lenses be a bad choice to do this sort of work professionally? I am debating picking up a prime 55mm 1.8 lens and a 18-200mm nikkor to use both for portraits. I am looking for advice or if you want to laugh at my lack of understanding of modeling and portrait technicality be my guest.
