Looking to buy a D/50/70/200 and have number of old film Nikkor manual lenses, one in particular that I like is a Q (series ??) 135mm f2.8. I used it mostly for portraits but thought it would be too long for 'around the house' digital use. I have no experience with SLR digital manual action etc as my only digital experience is with Nikon coolpix 990. Your impressive results with 135mm AIS (???) is inspiration for me to make a purchase of a camera body and try manual techniques first. Am I crazy? As a novice which body should I buy D50 or D70 ?
