He did my 135 2.8 lens this past summer. Awesome job and super quick turn around. Highly recommended.

If you are such a lover of Pre-AI lenses, then you wouldn't have them "converted".

Why not?

None of their functional attributes are lost in the conversion. Perhaps if you consider the lens a collectable it's not a good thing but from a functional perspective it's just fine.

I have many non-AI lenses and love them. I especially like the fact that their non-AI nature prevents them from being mounted on the lesser Nikons that followed the mighty F, F2, and FM. Well, there is also that weird Df thing.

Because they loose their original condition. Further many Pre-AI lenses have an aperture ring that goes around and over the body mount. To be "converted" that ring has to be changed or worst, just filed.
It doesn't loose functionality on Pre-AI bodies, but it isn't a full AI sepc. It misses some AI functionality. For that reason the F4 can't do Matrix metering as it does with genuine AI lenses.

I suppose in some (perhaps rare) cases, the converted to AI lens doesn't have the same functionality as a true AI lens. But the converted lens I've used worked fine on my ft2, fm2, fe2, f2a, n90s - at least in the modes I've used them. No experience with the F4. Of course, the conversion is to an "AI" lens, not an "AI-S" lens.

Think the FG-20 dedicated flash is dependent upon the max aperture indicator.

 

[Ricardo Miranda]

Yes, it is, as it is the EM.
When Nikon offered the AI kits, it was on the base to offer compatibility with the existent cameras in 77. They had incorporated the max aperture post in the AI spec, but didn't used it until 79 with the EM.

very funny,but I like them to fit my cameras.makes better images that way

Not to mention the bottom of the line DSLRs like the D3000 series. I'd rather have them converted so they work on all my cameras. But none of mine are collectable.
