The repair of the foggy 42/1.2 PenF lens was on my list (usable but with very low contrast). Last weekend I unscrewed it from front, and the 2nd and 3rd element (a cemented doublet) came out nicely.
The fog is right between the elements. So next step would be to segregate them, clean, and re-cement them with canada balsam. But I find no way to lose the ring holding the doublet. No threads whatsoever. Could it be pressed together? Don't want to apply any force here.
Anyone has repaired this lens already? I have seen some 42/1.2 lenses offered with fungus/fogging, so this is a common fault probably.
I already asked a repair guy who works with Olympus here in Germany but with no effect.
It would be a shame to leave it uncured because it's a very nice example of that quite rare lens.
Any help would be appreciated.
