"I don't think that's correct. Folks have attributed the difficulties to the body (and the format), not the flash."
In that case, what reason is there to expect the new Sigma flashes to work as they should with the *ist D? For that matter, if the problem is the camera itself, does any TTL flash work correctly with the *ist D other than the rtf? I pose the question seriously.
Question for Bruce Dayton: Does your AF 400T perform TTL correctly with the *ist D?
Thanks,
Joe
