    Hainvg a dust problem, but not on the sensor. I've got dust on the
    focusing screen. I've tried blowing it off, but some appears to be
    held permanently in place by electrostatic forces, or glue or
    something. At any rate, I can't get it off. It's really just a
    distraction, not a problem, but it drives me crazy. Any suggestions?

    Sable artist's brush. You should be able to get one at a hardware store
    dirt cheap or at an art supply store for a little more. Rinse it and
    let it dry before you use it--some of them come with a sizing on them
    that makes them pretty stiff until they've been washed.

    If that doesn't work, then get a sensor cleaning kit--if it's safe for
    the sensor it should be safe for the focusing screen.

    FWIW, I got this kit a couple of years back
    &keywords=dslr+sensor+cleaning+kit> and cleaned the sensor three times
    since--it works fine.

    Usually a Giotto's "Rocket" blower, or a chamber brush should deal with
    loose dust. If the dust is stuck or persistent, then I suggest using a
    sensor swab or PEC pad with spot of "Eclipse" fluid to wipe down the
    interior of the chamber, including the focusing screen.

    I usually buy my cleaning supplies from MicroTools & Photosolutions:

    Thanks. I'll give those a try. Yes, I've got rocket blower, but
    even it doesn't seem to be able to get rid of these particular specks.

    There is also the possibility that the dust on the screen might be on
    the prism side, not the chamber side. That might require removal of the
    screen for cleaning. If you are not up to that, then you might have to
    find an authorized manufacturer's service center to handle it for you.

    Does the camera have an interchangeable screen? If it does then you could
    remove it from the camera for cleaning.

    Regards, Ian.
