Sizzling Flash sound from Pentax *ist DL?

    Hello all,

    I recently received a replacement *ist DL after I returned my old one
    for a non-functioning flash.

    However, I'm now seeing (or rather hearing) some behavior from my new
    *ist's flash that makes me wonder whether everything is okay.

    In dark situations, when the camera is having difficulty focusing, the
    flash pseudo-fires twice to help the autofocus. That's no problem, but
    when it pseudo-fires like that, the flash makes an almost sizzling or
    buzzing noise that's very noticable. Is that normal? I don't remember
    my first *ist doing that, but then again, its flash eventually failed
    and so it may not have been at full speed from the beginning.

    Am I just gunshy after being burned once? Can other *ist DL owners let
    me know if their cameras do the same?

    Cheers,
    Chris Hafner

    I don't have that camera, but is it possible that the autofocus-assist
    is done by pulsing the flash on and off rapidly? I know that my Nikon
    speedlight buzzes when I use the modelling light, for that reason.

    That's the flash discharging so the auto-focusing system can get a read on
    what you're trying to shoot. After all, the camera needs light to focus,
    right?

    I think he already acknowledged that, don't you?

    As in "... the flash pseudo-fires twice to help the autofocus. That's no
    problem,.."
