    I have some large dust particles on the inside of my AF-S Nikkor 18-70
    lens, and I want to clean it.
    I found very little information on web searches, I tried to
    disassemble it but stopped short of getting to the front lens, I
    wasn't sure how to get the last parts apart. I made it to the
    mechanical parts and got stumped, it wasn't plain to me which sets of
    screws were next, or how I could be sure I could get it back together.
    It is reassembled and working fine (except dusty) so I think I will
    succeed if I get help for the moving parts. For all I know I was past
    the hard part!
    I will try it again if I can find something to teach me, like a simple
    step by step set of photos or descriptive text for that series of
    If anyone knows where I can find the info, I would greatly appreciate
    the link, ...or suggestions

    DON'T DO IT.

    I once had a problem with a Mamiya (645) lens and managed to screw it in
    the process.

    Get a price from Nikon - and the work will be guaranteed - assuming the
    lens is not still under guarentee of course? There should be no dust
    inside a lens that's only a few years old so you could try chatting them
    into doing it for a reduced fee if not free.

    And It may not be dust but spots of Black paint on imperfections to stop
    light scatter.

    Thanks for the replies,
    As for don't do it, I've already had it most of the way apart, and
    only stopped because I hit a choice I couldn't resolve. I think I was
    only one or two steps from the end. Unless I have another primary lens
    {don't have- unfortunately}, I am not willing to send it away for
    however many weeks Nikon will take to return it.
    I've ruined a lens before too, that really sucked. I lost track of the
    order and orientation of elements, it let grey light through and
    that's all. I don't believe that's an issue with this lens, I can't
    screw up the order of the glass elements. That old disaster is keeping
    me more attentive to control now.
    I am certain it is dust, I have looked carefully with magnification
    and side lighting.
    When I bought my camera, somebody came in the store to complain about
    dust in their Nikkor, same series as mine, and he was basically blown
    off, not part of the Nikon (or extra) warranty. Mine's out of warranty
    now so I expect no sympathy from Nikon, or the impersonal store.
    I agree that a 1 1/2 year old lens shouldn't have dust in it, but it
    is a zoom, I zoom it in and out frequently, I wasn't lucky long
    enough. I would have thought Nikon would build it better, the dust I
    see is not tiny, and on certain shots it am sure effects the image.
    On the other hand, if I can talk myself into a new lens (I'm getting
    there) and a repair shop that's reasonably priced, maybe I'll go that
    I still prefer to do it myself, especially if it needs repeated
    Thanks again for the suggestions
