I have an interesting situation with my EF 500 flashes. (same thing for both of them)
In on camera TTL mode, I can shoot with flash straight on to the subject and things work fairly well, although usually overexposed. When using on camera TTL and bounce flash or a Gary Fong Lighshpere...always underexposed by several stops and not recoverable.
Now for the anomoly. If take the flash off the camera and put it on a flash bracket so it is several inches above the camera (or hold it away from the camera, or set it on a light stand) and shoot in wireless TTL mode I can shoot straight on, bounce and even use a Gary Fong Lightshpere and all works wonderfully well. (straight on will overexpose somewhat)
For my purposes this is fine for the most part, however I have had a couple of situations where wireless was not useful with the flash on a bracket above the camera as the flashing red light from the flash warns subjects when trying for candids. So, I put some masking tape over the flashing red light and find the exposure is still correct and the subject has not been alerted by having it flash in their eyes. (I have also just found I can cover the built in flash when in TTL mode and the EF 500 on the flash bracket with no ill effect)
For some reason, both my brand new EF 500 flashes work excellently in wireless TTL mode, however, not as well in on camera TTL. I bought them after finding I just could not get the EF 530 Super to work in wireless mode.
Any comments?
