I've used eos3 and 550ex and found this minor problem a few years ago. Here it is; Camera In AV or M mode sitting on top of a tripod. A flash is on the hotshoe and turn off. The ambient light is below EV7.(FYI, EV14 2/3 is equivalent to sunny f16 rule) Then the camera say f/4 at 1/8 as a correct exposure in the viewfinder. But when I turn the flash on, the camera say f/4 at 1/15 as a correct one. It seems to me that it try to underexpose the ambient/background by 1 stop when using flash. This underexposure problem exist only at EV7 and below. This surprises me very much. So when I want to use flash to balance the light between background and my subject, I must use M mode and turn the flash off before metering the background. Then I turn the flash on and never care of what the metering say. I once read from photo.net thread that a guy had the same problem with his eos1v too. But it never happen with my eos50e. Do you have any comments?
