The elegant Nikkor non Ai to Ai conversion
Offering Unique Conversion Service for pre-ai or non-ai lenses, which will allow them to be used on Nikon Digital cameras equipped with an EXPOSURE METER COUPLING at the lens mount. (D300’s, Df, D750, D800, D850, D4, D5 etc)
Further advantage it will also work with Nikon Film cameras with metering tab.
With this service your lens will be professionally modified. You will now have full colour matrix metering and set the aperture by moving the aperture ring on the lens. Like you did in the pre digital age.
This high precision conversion is the only modification method available which is not visible on the outside of the aperture ring of the lens.
Works for following Manual Focus lenses Nippon Nikkor Kogaku:
|24mm||auto||1:2.8||N & N.C|
|105mm||auto||1:2.5||P & P.C|
|135mm||auto||1:3.5||Q & Q.C|
|200mm||auto||1:4||Q & Q.C|
Update 2021: Above list is not complete. For lenses not listed here I also have very nice solutions.
The cost for this modification is only GBP 18,00 excluding return postage. Turnaround time is normally within 3 days after receiving the aperture ring. Interested? Please contact me for more information via my email: firstname.lastname@example.org
In order to keep postage cost low preferably you disassemble the aperture ring from your lens and only send me the aperture ring with lens information. In many occasions removing the aperture ring is very easy. If needed instructions can be provided.
Advantages: compatible with analog and digital Nikon cameras, not visible on the outside, full metering and most of all not impact on the value of your lens.
Arguable a more elegant solution then a Nikon Ais aperture ring!
