Landiah Posted November 2, 2019 Share #1 Posted November 2, 2019 Advertisement (gone after registration) Long story short: I used a bit of super glue on my lens cap and after letting it dry I replaced it onto the lens. To the horror the fumes covered the glass in a milky white coating which I was able to clean off but am left with some new streaks. Needless to say I’ve learned my lesson. Anyone have any idea what these streaks are, how they will affect image quality, and if it’s possible to fix. Looking through the lens you can see them at the top as slightly darker streaks Welcome, dear visitor!

250swb Posted November 2, 2019 Share #3 Posted November 2, 2019 What did you use to clean the fog off the lens? The remaining mark looks like residual streaks of cleaning fluid or detergent based product, try Isopropyl alcohol. If you can't get them off the marks will not affect image quality at all and nothing to worry about. Link to post Share on other sites More sharing options...
AndreasG Posted November 2, 2019 Share #4 Posted November 2, 2019 I never would use super glue on a camera lens, the fumes trouble is well known. Once the little red hemisphere fell off from a M lens, I reattached it with a tiny drop of 2K glue, which hardens within a few minutes without any fume residues.

M9reno Posted November 2, 2019 Share #5 Posted November 2, 2019 It’s hard to explain how fumes, even had they penetrated into the lens, would show up as interior streaks. If it streaks, it must outside, and left over from your first attempt to clean. Clean again and all will be well. Link to post Share on other sites More sharing options...

Fumes aren't a problem if you use a non-fogging superglue especially made for clear plastic and glass, available from all good hardware stores near you.

In case of some lens work I would not rely on the statement non-fogging. As long as you can smell the glue the molecules are in the air and vicinity.

tobey bilek Posted November 3, 2019 Share #9 Posted November 3, 2019 Acetone is solvent for super glue. Recreate the fog on an old filter and see what acetone does to clean Link to post Share on other sites More sharing options...
otto.f Posted November 3, 2019 Share #10 Posted November 3, 2019 Did you examine your lens that thoroughly ever once before the glue action? Link to post Share on other sites More sharing options...
