Hi. Does any one know the rough cost of getting an standard lens profesionaly cleaned, ( inside )??? Im trying to hold off from spending, so I thought Id se if it was worth while paying for a clean rather than a new lens. I have a Cannon 350D, the kit lens is great for what i need with the 18mm focal length, but for some reason, there is an uncomfortable amount of dust inside behind the glass, god only knows how it got there, bit i cant shift it. Any Ideas? Or pointers to getting it cleaned? Cheers.
