I got a nikon F80 and two lenses - one sigma 24mm and one nikon zoom lens - 70-200 mm i think. All have work very well until resently. It has been used in a very dusty enviroment and now every time I use the autofocus, horribly grinding sounds comes from within the lenses. I suspect that dust is the issue - What can I do - I don´t have alot of money and therefore sending it to be fixed at a professional place is not an option at this point. Can I fix it myself ? any suggestions.
