    Way up there.
    I was wondering if anyone has any knowledge of non ai nikkors, such as the Nikkor-P, Nikkor-H, etc. I was interested in the primes, specifically the 24,28, and 50. I know there is many other varieties of non-ai lenses, but i hear things about saying the lens has to be modified before use on cameras. What exactly does the modification entail, and is it needed for use on micro four thirds with a standard adapter. What about focal reducers? Other than this, is the performance of these lenses any good, or should i just skip them and wait for a good deal on an AI-S or AI lenses?

    Non-Ai, Ai and Ai-S are all the same physical mount and, as far as I'm aware, the differences only affect their use on Nikon cameras as regards auto-exposure. Non-Ai lenses can't be used on modern Nikon DSLRs and can therefore be a bit cheaper. As far as how they work on M4/3, I think they're all the same.

    Not trying to shoo you away or anything, but as many questions as you have about manual lenses, you might find one of the specialist forums like mflenses or manualfocus to be useful.

    Not "auto-exposure", but any and all meter coupling, whether for manual or auto.

    With the exception of the few rare lenses made from 1959 through circa 1961, all Nikkors with fit almost all adapters for m43 without any conversion. Some adapters may have issues with those very early lenses, but those are generally collector's items selling at premium prices.

    There were 21mm, 35mm, 50mm, and longer lenses in those early days, but all 28s and 24s are much newer and won't be an issue. I would avoid the early variants of the 28mm f/3.5 for quality reasons.

    Its worth having a nosey around the adapted lens showcase - a few Nikkors in the catalog but they're not necessarily labelled by 'Non-AI' status . . .

    I've got a f1.2 & f1.4 non-AI in that early-adoption enthusiasm for all things speedy. They're lovely to handle - a serious chunk of glass and steel. In retrospect, I'd have been better off saving for a suitable native m43 equivalent to get the benefits of more modern lens design and coatings. Still, adapted glass does have a certain character to it that is hard to replicate.
