Ai Conversions for Nikon Lenses by John White

Update as of August 31: October 2025 will be a busy month for me. I may not be able to always fulfill my "no more than a few days" goal for turnaround time. Thus, orders received in September or November will have a better chance of a fast turnaround.

Thanks for finding my service. I am still converting pre-Ai* Nikon lenses while my website is under renovation.  Fortunately, the previous one is still accurate in terms of key features (and prices). You can go to the home page of the old site and get started from there or just print the order form. Note: The version on the old site can be filled in electronically.

For some basic updates from what's on the website:

Thanks to all my past and upcoming customers! I hope to get my aged website updated eventually.

* Ai stands for Automatic Indexing (not Artificial Intelligence). :-) Pre-Ai lenses date from 1977 and before. The primary identifying characteristic is an aperture ring with only a single set of f/stop numbers. Ai lenses have two sets.
