Jack,
I am using a Vivitar 730 TTL flash on my ist-DS. It has a Hi/Low switch
and at ASA 200 the Hi position burns out the highlights of anything
inside about 10 ft. The low position takes a good picture. This seems
to be true on both Program and green modes. It may be that the flash
cannot be backed off enough even at the lowest ASA setting. ARe you
seeing something similar with your shots??

I have an istD with 330FTZ, 400FTZ and 500FTZ flashes.
The camera is in green mode and I take flash shots at ISO 200, 400 and
800 ASA all from a tripod, the same subject and the flashes in
auto-TTL mode.
The 200 ISO shots are all underexposed, 400 ISO is more or less
correctly exposed and 800 ISO are all overexposed.
The IstD manual recommends 200-800 ASA for these flashes.
The solution would be to allways use ISO 400 for flash which would be
very strange.
