oh oh.. i noticed black "oil slick" like spot on then front of my lens. not sure what it was... i rubbed it, and it got bigger.. so i just did what any rational person would do. kept rubbing.. it seems i rubbed off a "coating" of the lens? what does this do? probably some sort of flare protection? its 10pm so i have not had a chance to test it.. needless to say, i'm bummed.
