Once again Mikey is gonna show some ignorance. If you're strapped for cash and taking a lens to a dealer / store is out of the question, how hard is it to dismantle a lens and clean it? My second hand ones that came with the camera seem to have dust inside...... Cheers! Mike btw, typing that title reminded me of a joke - if you're easily offended, don't read any further. I've warned ya. Two little boys were out in the woods playing one day when one of them gets a thorn in his finger. Screaming with pain, he asks his friend what he should do to stop it hurting. His friend says "Well, there's a Bar just down there, we can go in and ask the man for a glass of Woodpecker to put your finger in, that should stop it." "How will that help?" Says the other "Well, my sister was talking to her friend Tracy and she said that whenever she gets a prick in her hand she has to put it in cider.........." Tee hee. (",) (btw, just in case you Yanks need it explained, Woodpecker is a brand of cider. Cider is an alcholic drink made of apples and looking much like dark lager. Now read it again and you'll get it.
