ondrejp_spyderman Posted January 10, 2007 Share Posted January 10, 2007 Yesterday I did the cleaning work on my friend's OM-1. One of the first series, incompatible with motors and winders.<br><br> The foam seriously damaged the prism silvering. According to <a href="http://olympus.dementia.org/Hardware/tutorials/FoamRemoval/index.html">this article</a> I removed the damaged part of silvering, but it's still nasty...<br><br> 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.<br><br> See the following pictures from the cleaning procedure...<div></div> Link to comment Share on other sites More sharing options...

tim_kohlman Posted January 11, 2007 Share Posted January 11, 2007 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. Link to comment Share on other sites More sharing options...
konrad_beck1 Posted January 12, 2007 Share Posted January 12, 2007 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.

ondrej_p. Posted November 24, 2014 Share Posted November 24, 2014 <p><strong>WARNING</strong>: the information "this is only true for OM-1 and maybe OM-2, not the "N" versions or anything later" is incorrect. <strong>Some N versions indeed do have the foam.</strong> Recently a very high serial number OM-2N had the foam, but fortunately the prism was still intact.</p> Link to comment Share on other sites More sharing options...
