    I just upgraded from a 300D to a 5D.

    I noticed that the noise/sound when taking a picture consists of the mirror
    & shutter movement followed by something that reminds me of film advance.

    Any idea what that noise is?

    The shutter being reset; perhaps?

    Have you tried mirror lockup with a long exposure to isolate some of the

    No - I'm just curious about the noise the camera makes

    I did what I suggested with my 20D - I was quite surprised that most of the
    noise was mirror slap, and very little from the shutters.

    The mechanism is likely under damped for whatever reason.
    I remember some film SLRs had pretty hard mirror slaps, tended
    to blur images in some instances.

    Only if you hold the camera very loosely. The mirror is *quite*

    It's easy enough to check.

    The 20D has a loud mirror, and I can hand-hold just as well as I did
    with my quiet 10D.

    An interesting experiment might be to mount a camera on springs, use the
    self timer, and see how different cameras bounce around after the mirror

    I remember a test done many years ago with SLRs and some of them had
    such brutal slap (Ricoh I remember as one brand) even mounted on some
    tripods they produced some image blur. Olympus had one of the softest
    impacts, some Canons were well-damped as well.
    A way to really measure it would be to mount a laser pointer on the
    camera and point it at a wall some feet away that had a tape
    measure attached. You could even calibrate it to where you knew which
    shutter speed you'd need to counteract any vibration, with any lens,
    at least when the camera was spring-mounted.
