If it is fungus, the UV in the sunlight will kill it. Agree since cotton fibers usually will reflect strong light in whatever angle it point at, and the pattern doesn't look like fine scratches that's common in Leica lenses. If the elements is not at the front surface than you need a bit more time under UV/sun since glass effectively block most if not all UV lights. I will choose sun since the heat of the sun can dry out the whole lens and dry out (kill) the fungus much faster. Link to post Share on other sites More sharing options...
