    Is it possible for a small compact
    to get dust on its sensor?

    I thought only DSLR had this problem
    because their lenses could be removed.

    I have a HP 707 with this problem.
    Spots show up on pictures with large
    white or blue sky areas.

    What can be done about this problem?

  2. Usually, the compact camera has a sealed sensor, making it very difficult
    for dust or dirt to get in. You might like to post a picture so that
    people can be sure dust is really the problem. If shaking the camera
    doesn't help, you may need to send it for repair (or buy new). You can
    reduce the effect on the image with a program like Paint Shop Pro.

    Cheers,

    The volume of the most compact camera's is NOT constant.
    Air presure is not constant.
    The space in front of the sensor is air.
    (Compact camera's do not have a sealed sensor).

    Because of the volume change (zooming etc). the camera is not
    airtight, this means air gets sucked in and blown out. While extending
    the lens this is going quite rappidly, so there are some 'large' holes in
    the camera. When the air get's sucked in, dust get's sucked in as well.

    Depending where the camera is kept, there will be dust on the camera.
    Keeping the camera in a camerabag which is 'clean' will keep the camera
    clean as wel (fairly). Keeping the camera in a dusty surrounding, for
    example in your pants or your pockets in your coat then the camera will
    get dusty.

    Zooming makes that air (and if present) dust get's sucked in.

    Sensors in most compact camera's are very difficult to reach even for
    professionals and often the operation of removing the dust is so
    expensive that the camera is not worth this operation.

    So with the camera, you are probably stuck with the dust.

    The sensor is sealed. Period. The air round the sensor is not, as you
    say.

  5. Dust on a compact`s sensor? That`s very unlikely.
