I'm going to be doing a search on the forums for my question but I'm gonna ask it anyways. If I find the answer before anyone replies I'll erase this post... if that's alright. I have had my lenses for well over 10 years and after that length of time and the simple fact that they aren't "dust proof" like the more expensive lenses you can buy now I have noticed small specks of dust getting into the interior of the lens. I know I have to take it somewhere to clean it as there is NO WAY I'd attempt it myself... so where do you guys suggest I take it? Any recommendations from you guys would help me out a lot! NOTE: the dust particles aren't showing up on any of my photos yet but I still want to know the best place to take them anyways. TIA ttfn CDL.
