Well... I noticed some crap on my pictures which turned out to be some sort of a metal flake or something on the inner element.. me being the genius I am I decided to take it apart... little did I know that it's just about the hardest element to clean as the entire lens must explode into a billion pieces. I got it apart, cleaned it, and now I can't get the damn thing back together again and to tell you the truth, I never liked the quality of the lens anyway. What is a good alternative to the lens, preferrably one that is a little sharper and maybe has a little more angle to it. I currently have a 70-300m VR zoom lens, so I'd be happy with something that fills in that 0-70mm optic range. I appreciate any input.
