I've purchased a new 45mm PC-E and would like to have the shift axis aligned with the tilt axis for landscape work. Would those of you who have had this done by Nikon USA tell me about your experience. I'm particularly interested in: 1) The cost of converting a new lens. (Nikon USA couldn't provide a cost over the phone - strange.) 2) The approximate turn-around time. 3) The quality of the work performed. Thank you.
