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:

24mmauto1:2.8N & N.C
35mmauto1:1.4N
50mmauto1:2H
55mmauto1:3.5P micro
5.8cmauto1:1.4S
85mmauto1:1.8H
105mmauto1:2.5P & P.C
135mmauto1:3.5Q & Q.C
200mmauto1:4Q & Q.C

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.

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!

  1. Wonderful servicing. Fast turnaround and the 50mm 1.4 now fits my D700 like a glove. Also wonderfully restored is my 28mm f3.5 which looks pretty much new now!

  2. Thank you Marcel for doing such an exquisite and prompt conversion on my pre-AI Micro-NIKKOR 55mm f/3.5. It now happily mounts on all of my Nikon bodies that have a meter coupling lever.

    Thanks Marcel for your excellent conversion on my Nikkor 300mm f4.5 AI. It works like a dream on my Nikon 7000 & Nikon FE and FM.

  4. Marcel has modified my Micro Nikkor Auto 55mm f/3.5 very elegant and now I can use it on my D850 with metering. Thanks a lot. Marcels Service gives a very good value and is less expensive than the freight-costs from Germany to GB (:-). And – also important: Marcel is extremely friendly and competent. From now on I will send every old lens, I can get, to him for modification …Ralf
