    I have a 24-85 f3.5-4.5 AF-S and it has some dust inside the lens. How much do you think Nikon will charge to clean it ?

    I bought it used.

    Do you have to look at a light source through the lens to see it? If so, it probably won't be much of a problem, especially if it's near the front of the lens. I've found the only thing that seriously degrades lenses are smears and fingerprints. Especially on the rear element.

    it actually has a lot of dust in between the lenses... you don't even have to look at it thru a light source.

    If you do any landscapes with the aperture stoped down all the way ( F16-F22), that is where it may begin to show up.
    Nikon does not touch a piece of equipment for less than $200-300.
  5. Hi Ed --
    I have written before about my love/hate relationship with this particular lens. I call mine the Dear Old Dust Magnet. I had the lens cleaned twice under warranty during the first 2 years I owned it. After cleaning, it promptly filled up with dust and fibers again within 2 weeks or so. So I've stopped sending it in for cleaning even tho it's still has some of its 5 yr warranty left. Too much trouble!!

    Anyway, I really do not think that the dust, even on the rear element, will cause a problem with this lens since you won't likely be doing any macro work with it. At most you might get some flare if the dust was "large", relatively speaking. But I had an almost half-inch, thin red fiber on the rear element of mine and even that did not cause a problem in the photos. (That surprised me really, but as Chris pointed out -- it's smudgy stuff that causes problems, not specks or fibers.)

    If you let the lens set in a cold place (not too cold) or a hot place (not too hot) for awhile, the dust sometimes falls off the rear element and settles elsewhere for a while.
    Hope this helps!!
