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
