Even though the shutter is rated to an astounding 150,000 actuations (over 4,100 rolls of film), after 7 years of moderate use I decided it was time to send in the Nikon F6 for servicing, while I felt I stood a reasonably good chance of still getting parts. While in the shop it made sense to have the non-Ai modification to the lens mount made to allow those old, beautiful non-Ai lenses to be used by the camera. This post chronicles the process from a Nikon Professional Services (NPS) member's point of view.
