jfserejo Posted January 8, 2008 Share Posted January 8, 2008 Hy, taking the risk of this could be a really dumb question, I was wondering if theNon-Ai Nikkor lenses mount problem in recent body's is mainly because of theMeter-coupling prongs position in the ring? And if so, is it possible to unscrewthis prongs and mount safely for working meterless? Thank you so much.My best regards,Joao Link to comment Share on other sites More sharing options...
kaiyen Posted January 8, 2008 Share Posted January 8, 2008 yes, they pose a consider risk. As in damage the camera kind of risk. I believe they can be modified, but they are not technically compatible. I don't know how hard they are to modify. allan Link to comment Share on other sites More sharing options...
michael_bradtke Posted January 8, 2008 Share Posted January 8, 2008 Its not the prongs on the lens. Its the AI follower on the camera that is the problem. Link to comment Share on other sites More sharing options...
jfserejo Posted January 8, 2008 Author Share Posted January 8, 2008 dam, I was so hopeful... Well it will be quite a challenge to find a place to modify these lenses here in Europe. Thank's Allan and Michael Link to comment Share on other sites More sharing options...
james_lai Posted January 8, 2008 Share Posted January 8, 2008 Which body do you have? If you have a D40 you're in luck because that body can mount non-AI lenses. Link to comment Share on other sites More sharing options...
jfserejo Posted January 8, 2008 Author Share Posted January 8, 2008 Hi James, I had an FM2n and FM3A so I will have to modify these lenses or try to find an inexpensive older body (which may be cheaper than modifying these 4 lenses I received from a family member almost unused) Link to comment Share on other sites More sharing options...
pge Posted January 8, 2008 Share Posted January 8, 2008 It is also safe to mount them on an fe which you can probably buy for 30 dollars these days. Phil Link to comment Share on other sites More sharing options...
bgelfand Posted January 8, 2008 Share Posted January 8, 2008 I had my lenses convert to AI by John White. http://www.aiconversions.com He did an outstanding job at a reasonable price on my four lenses. If you have several lenses and ship them together, the shipping cost should be manageable - compared to replacing the lenses with new versions. Call Mr. White and talk it over with him. He is a gentleman to deal with. Link to comment Share on other sites More sharing options...
jfserejo Posted January 8, 2008 Author Share Posted January 8, 2008 Brooks, I saw John White website and is very tempting to send over the lenses, the problem is that apart of shipment, some times items that came from the US here in Europe are taxed inexplicably in the customs!

oskar_ojala Posted January 8, 2008 Share Posted January 8, 2008 It's easy to have the aperture rings of the lenses modified to fit an AI body. A local dealer here did it for one of my lenses for 40 euros. I didn't have the tools myself, so 40 is quite inexpensive. If the repair shop has old aperture rings meant to adapt these lenses to AI, then it should be even cheaper to exchange the rings. Link to comment Share on other sites More sharing options...
radfordneal Posted January 8, 2008 Share Posted January 8, 2008 As noted above, the Nikon FE, as well as the FM, F3, and (I think) F4 can mount non-AI lenses. BUT, be sure to read the manual first! In particular, learn how to push the little button to move the AI coupling tab out of the way, or you could damage the camera trying to mount the non-AI lens. Also, remember to move the tab back when you want to use an AI lens later (or your metering won't work). Link to comment Share on other sites More sharing options...
rogerdb Posted January 8, 2008 Share Posted January 8, 2008 I've done my own. Their is a lip that surrounds the mount on Non AI lenses. This lip interferes with many newer cameras. I use a dremel motortool to grind away the lip so that it doesn't interfere. If you look at how the lip is removed on newer lens you should be able to see what needs to be removed. If your not very handy- of course- don't try it. Tape up the entire back of the lens, the focus seam and front of the lens to keep metal shavings out. I've done several lenses. 24mm 2.8, 50mm 1.4, 28mm 2.8, 135mm 2.8. and use them with my digital cameras. Link to comment Share on other sites More sharing options...
jfserejo Posted January 8, 2008 Author Share Posted January 8, 2008 Thanks a lot all. I think I go with a Late Nikkormat FT-2 - just saw one in a local second hand store and will be a cheaper, less painful solution for now. Once again thanks.

bgelfand Posted January 9, 2008 Share Posted January 9, 2008 Hi Joao, The only people who can give you a definitive answer to whether the lenses would be taxed upon return from John White are your customs officers. You should be able to call them and ask. There should be some way you can register them and avoid taxation. Link to comment Share on other sites More sharing options...
jfserejo Posted January 9, 2008 Author Share Posted January 9, 2008 Hi Brooks, you are right. Just as we do when we go abroad in an airport! This way sending the lenses may not be so expensive. Thanks. Link to comment Share on other sites More sharing options...
