If the flash isn't ready to fire, the camera will base its exposure on ambient light... I think all EOS behave this way. If you set a manual exposure via the M mode, the camera will "fall back" to that setting until the flash is charged and ready to fire. If the camera detects a shutter speed too high for flash sync when the flash IS ready to fire, the camera will set it to a proper X-sync setting based on how the custom functions are set. Nothing weird about it at all. If it didn't act this way, you'd have a lot of dark/black photos (no flash), or big black bands in the photo (from the shutter not being fully open) when the speed exceeds X-sync. You know, like we used to have to deal with before cameras became smarter than photographers. :-) MadMat __________________________________________________ Do You Yahoo!?
