A speck of dust won't hurt anything. I am much more bothered by the thought of taking a lens apart to clean a speck of dust and then reassembling it without having a collimator handy to be certain that all the elements are properly centered than I am by a speck of dust.

I have never had anything in any of my lenses before, so I am at a loss as to how to save my lens. In this regard, I have a couple of questions. How much does it cost to have a lens taken apart and cleaned by a repair professional? Is it possible for an amateur, like me, to take apart a lens, clean it, and put it back together in working order? What are the tools and steps needed for me to clean this lens properly? Thank you in advance for your help. Village Idiot
