Not sure about EOS 300, but for D30, flash in Av and Tv mode is only FILL FLASH ie it meters off the ambient light.
If you want a faster shutter speed, best way is to go manual. That way the flash will output more power to provide enough light for your exposure.
And on Nikon systems, in the Av mode, the flash will automatically set the camera to the flash sync speed (e.g. 1/250) unless you explicitly ask for slow sync/rear curtain sync. But when I am shooting indoors with flash, I use manual.Originally posted by erwinx
oh, yet another difference between Nikon and Canon's flash systems
Nikon can do both slow synch or flash synch in Av and Tv mode. For my F70+SB-26 combo, I shortcut the F70 navigation menu by using the normal/rear switch on the SB-26 (since rear synch flash switches to slow synch mode, while normal defaults to flash synch unless overriden by camera body)
