Originally posted by res3567 Yes Ash it is confirmed! EV does adjust the flash ouput. I just did a series of tests adjusting BOTH FEC and EV and I DID see a difference! My theory is that the camera is telling the flash to increase its output as the shutter speed does not change.
Yes, I see the same result. I found this thread looking for that very point. The camera's EV shouldn't logically have an effect, yet it does. That seemed wrong, so I came looking, but you guys are seeing it, too. Guess it's a "feature."
I just shot an "average living room scene." Sigma EF-530 DG ST in P-TTL mode, FEC 0, on a K10D. Camera in "P" mode, normal program line, ISO 100, EV 0. Camera selected 1/30s, f/3.5. Badly under-exposed.
Second shot, identical settings on camera and strobe, except the camera's EV was set to +2.0. Camera selected 1/30s @ f/3.5 again. Much better. Maybe 1/3 of a stop under-exposed, if that. Bizarre.
