OK, my other thread is really messed-up, and off-topic, so I thought I'd begin again here.
Anyway, I have a Pre-AI 50mm ƒ/1.2 that I use on my F2 Photomic. However to be able to use it safely on my cameras it should be AI converted (I had a pretty nasty experience, you can read about it on my other thread).
I do know that http://www.aiconversions.com will do a conversion for you. But I have a few questions:
Will the lens still work on my F2? It seems like the coupling "yoke", as it's called, is installed differently on AI and pre-AI lenses. Won't that mess up the coupling with my F2?
Does Nikon still do AI conversions? I'd rather have them do it.
How does the AI-conversion-guy do it anyway? If he can do it, why can't I?
