The main reason I ask is that I saw someone using another brand of DSLR and
the camera refused to fire at all because of some parameter being wrong
(and I think it was because the camera decided the exposure needed flash).
I want to always be able to make an exposure regardless of how wrong it may
be, and to make that exposure without any interference from the camera.
As others have mentioned, the flash can be told, "don't ever
bother me, unless I ask!" One thing I'll mention is the "refusing to
fire" issue. The *ist-DS will do that if you've got a MF lens on, but the
AF switch in the AF position. If he's not happy about your focus choice,
he won't fire.
It's gotten me quite a few times. Now I just leave it on MF
unless I *definately* want AF.
