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. >> Stay informed about: Does a digital camera still use a lens shutter or focal pl.. |

Yes.

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 :

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. >> Stay informed about: Does a digital camera still use a lens shutter or focal pl.. |

Then what keeps the image from forming on the CMOS when you aren't
taking a picture? >> Stay informed about: Does a digital camera still use a lens shutter or focal pl.. |

Nothing. And some are not CMOS. >> Stay informed about: Does a digital camera still use a lens shutter or focal pl.. |
