If your lens does not fall into the serial numbers above, we can not convert it to AI, as we use only the original Nikon supplied rings, and there is a very limited amount of the rings left. Price for all conversions is $45.00 plus $8.00 shipping. I get requests to sell just the kits without installation and this is not a problem but cost is still the same. Turnaround is usually 1 or 2 days in the shop. To return to home page for mailing address click here.
