I have still got quite a problem with one of my Elmo 1.1 Len's. It has a problem with lens fungus which i understand these suffer with.
My problem is just this, i have taken it to a local chap who was recommended by the London Camera exchange, unfortunately he seems to think he may do more damage taking it apart, i guess he doesn't have too much confidence which was disappointing considering he did camera repairs all his life.
There was a company in London that use to do these jobs but there now gone, and as yet i cannot find anyone anywhere in the land.
If it was a 1.3 lens i would just replace it but as you know these are quite pricey to replace if you can find one. A right pain in the doodah
