    Nikon F eye level prism issue

    I have a non metered Nikon F eye level prism that seems to be very slightly loose in its housing (slight rattle if you shake it). It looks and works well otherwise. Does anyone know how "normal" this is (or not). My guess is that there is an adjustment somewhere internally to correct this - perhaps some preloaded springs or whatever.

    the prism was held in place by foam padding that has turned to gunk by now, so it is normal. however, you should still send it to a repairman, because the gunk will damage the reflective coating.

    Thanks for the tip raizans. I have a local guy here that should be able to take care of it.

    Just had the prism from my F2 apart, it's retained by a couple of springs. No sign of foam at all.
    Heavily sedated for your protection.

    Looks like the F eyelevel uses a combo of springs and foam

    Bruce,

    Cool diagram, thanks. I'll pour a cup of coffee and study it a while! (I love these old school exploded views).

    Right now the prism is in the hands of my tech who also told me that he thinks there is a mechanical preload that needs setting. It seems that there is a spring AND foam.

    I don' know what it is about these eye level prisms and the original F, but I've been enchanted with them and the Nikon F from the day I went to press events with my dad back in the early 70's and met all the seasoned still-photo guys who swore by this setup (my dad worked for ABC television back then).

    I'm nuts for that camera setup, especially black, but I just got a very pretty chrome one also. It has the same simple and functional appeal to me as a Leica M2. And that was a classic combo too. Wide on the Leica and long on the Nikon.
