Getting lens opened & cleaned

    Apologies if this info is already in a thread, did a search without much success.

    There appears to be a bit of dust inside my lens (sigma 18-200 stabilized, if that matters), which I'd like to get cleaned out. Is there a camera shop in Dublin where I can get this done, and about how much should it cost?
    Thanks

    When you say inside the lens, can you see it on the images or just see it when you look through the elements?

    Stolen Borrowed from another forum
    In any event it's highly unlikely that dust on a lens element would be visible in the final picture. There's an old anecdote about an astronomer asking an optical scientist to make him a new telescope. Seeing little bubbles in the glass, the stargazer was concerned that it would affect the quality of his view. Optical bloke said not to worry... On using his new telescope, the astronomer was amazed at the quality and finally agreed that the bubbles in the glass had no effect. "Oh", says the optical bloke, "so you didn't notice the dozen postage stamps I stuck on the lens then?"...

    think it's just when i look through the elements, must do a bit of testing first

    Unless you can see it on the image I would not worry about it.

    just to tag onto this thread (and hopefully not hijack)... I noticed on some of my photos a very small hair which appeared to be on the lens, but has appeared on multiple lenses.

    So, its obviously in the camera. This hair has ruined quite a few pics on me. But it was only looking back at them that i realised they're only appearing in the raw pics I took. Im a bit of a newbie to raw format, but would it make sense that this would only appear in raw and not as a jpeg? :confused:

    I can post a couple of pics if necessary. Its not on all the raw photos, only some. Its on no jpegs, and when it does appear its always in the same place.
