Hi, Have my D80 set to Iso Auto. However when I use the built in flash (TTL) then Iso does NOT get automatically adjusted. In "P" mode with flash I sometimes get the exposure meter reporting underexposure so why does it not increase the Iso. If I do this manually it helps, or if I allow a slower shutter speed with flash that also helps. So..why does it not alter the Iso automatically with flash? Any idea's. Cheers, Harry
