Nikkor Lens
Is it possible to convert non-Ai leses into Ai lenses?

It is possible in most cases, but please note that it is not possible to put it back after conversion since a part of the lens ring will be cut, you cannot see F numbers from the viewfinder because it is not the ring replacement done at Nikon, we cannot guarantee mounting the converted lens in all of the products manufactured after 1999. Modification cost is 8,400 JPY. We need to check a lens to see if it has part to be cut. After checking a lens, we inform you whether modification is possible or not, and actual estimate.
