OM-1 prism destroyed by foam... bad experience

  1. Yesterday I did the cleaning work on my friend's OM-1. One of the first series, incompatible with motors and winders.

    The foam seriously damaged the prism silvering. According to this article I removed the damaged part of silvering, but it's still nasty...

    Just a word of warning: If your OM-1 is still OK, don't wait and get it removed and cleaned. AFAIK this is only true for OM-1 and maybe OM-2, not the "N" versions or anything later. I had a OM-1N apart, and there was no foam used.

    See the following pictures from the cleaning procedure...

  7. Nice writeup,

    I have the same problem with an OM-2 of mine which I'm looking at on the weekend. I might see if I can steal a prism from a dead camera it may be the better option.
  8. I have read somewhere that Olympus stopped using the prism foam for the OM-1 at around serial number 1,119,xxx but used it again at least for the early OM-1N models starting with S/N around 1,623,xxx.
  9. WARNING: the information "this is only true for OM-1 and maybe OM-2, not the "N" versions or anything later" is incorrect. Some N versions indeed do have the foam. Recently a very high serial number OM-2N had the foam, but fortunately the prism was still intact.
