TTL flash metering, by definition, is taking reflected readings off

OTOH, TTL flash as done on the istD has been less than accurate for
me. Preflash measurement is more accurate, I am led to believe, but
has the downside of slowing camera responsivness.
Accurate automatic flash has been the best compromise I have found.
Tim is confusing TTL flash measurement with the automatic exposure via
continuous OTF light measurement, which is unique to the LX (at least
I haven't heard of another camera that does it), and only works at
speeds below flash sync, the further from sync speed, the better
chance it has of working.

The Nikon F3, Canon New F1 and several Olympus OM models all do TTL-OTF
ambient metering. The unique feature of the LX is that it does so down
to -6.5EV, a range which is unheard of.
