I guess that explained why the blower was unable to blow away the dust.

I held my lens up to a light and looked through it, I saw some fungus like stuff... all over the area... []


I guess I have no choice but to send the lens back to Canon to get it clean asap and hope the fungus still not too serious until it has destroyed the coating of my lens.


Will camera body develop fungus? I normally hear people mention fungus in lens, will fungus grow inside camera body? In my case, will the fungus spread from my lens to my camera body? Also curious will fungus spread from one lens to another?
