    I have a Nikon F, circa 1970-1972 which except for the light leak is a fantastic camera. The F doesn't have a door but the whole back slides off to load the film- The leak appears to be coming from the bottom based on the streaked negatives.

    I am wondering if there is some goo, foam, or tape I can use to seal the back back better. It *appears* to seal nicely but clearly it isn't..

    I suppose in worst case I can tape up the seam with electrical tape but would prefer to stop the leak entirely if possible.

    Thanks!

    He doesnt list the F on his site, but maybe you can ask at http://aki-asahi.com/store/ . I got the seals for my Contax 137MA there and they work *great*.

    Just looked, there are two seals on the F, one is on the body along the top of the back, the other is around the tripod socket. Both appear to be a fabric cord type seal, not foam. check to make sure the three rivets along the bottom of the back aren't loose.

    Seal installation instructions

    A great resource for seals and how to install them is Jon Goodman he actualy has online information on how to replace the seals and has been responsive to my questions.
    Check his list of instructions here http://www.kyphoto.com/classics/sealreplacement.html if it's not on this list his email is there.

    Look at the seal around the tripod bush. I had to replace mine (with Jon's kit).

    Some of the older cameras use yarn or something that resembles it. I would expect this with the Nikon F.

    The reason is that you can't use foam when two parts are sliding back and forth -- that would tear up the foam rather quickly.

    I think you'll find that there is yarn to seal the top deck from the film chamber. And as kram points out, check out the area around the tripod bushing.

    At times I have been using black knitting yarn for those seals.
    That type comes in several thickness to suit your need.
    One package will last you a life time !

    I too, use a yarn for light seals on older cameras. Actually it's more of a heavy thread used for embroidery and doesn't have all the fuzz that most yarns do. If you spend a few minutes at the local fabric shop browsing their hundreds of different threads, you'll find something.

    I have some rubber/foam seals for an F2, would any one recommend taking the old yarn out and putting the foam strips in (film still in camera testing for current light tightness). Or stick to yarn (if I can find suitable stuff).
