Does a digital camera still use a lens shutter or focal plane shutter?

    With the new technology in digital imaging and sensors, does a digital
    camera utilize a physical lens shutter (or focal plane shutter in an
    SLR) to let the light passes to the sensor? Or, can the image sensor
    now be electronically turn on and off to allow for the light to
    register in the sensor?
    Thanks for info.

    DSLR uses a shutter just like SLR. That is why they have difficulty showing
    preview on LCD screen.

    Compact cameras have no problem with preview. Educated guess says they have
    no mechanical shutter.

  4. Yes.

    Depends on type, make, and model.

    Both mechanical and electrical shutters are used. Some cameras
    such as some of Nikon's DSLRs use both types of shutters. Most P&S
    cameras don't use mechanical shutters. For a good explanation of
    the whats and whys, see "The Importance of Flash Sync Speed" at :

    Within 2 years, the majority of new DSLRs will have live preview.

    Go figure.

    Most digicams have no physical shutter. That is why your
    should avoid pointing the camera at the sun at any time. You
    can ruin the sensor.

    Then what keeps the image from forming on the CMOS when you aren't
    taking a picture?

    Nothing. And some are not CMOS.
