I was just doing some experiments last night and this morning; came to
the same conclusion as you. I guess it's better than being consistently
over exposed.

I am having the same problem shooting yesterday. But I guess I
underestimated the lighting requirement (it is a windy, foggy at 5-6 PM in
NYC), and had gone ahead to use ISO 100 instead of 400.

Anyway, coming from a Digital P&S background(exclusively use of Spot
metering), I am struggling with the XT metering esp with bright background
and dark subject. Can anyone give some tips on how to use the metering on
the XT?

Thanks

If your non-flash photos are also underexposed, then there's reason to
suspect a defect in the unit.

What a lot of us with Rebel family stuff are seeing are fine ambient
exposures, but teh flash exposures are consistently under.

AMbient exposures on my 300D are quite accurate near as I can tell.
I shoot on P mode most of the time.
