Unless you're using fully manual for both the camera and the flash, then you'd need quite a bit of experience and have good calculations.
Like to check with u something..purely TTL..
A) When in Av mode + no flash mounted..ISO fixed at 200, Aperture fixed at f4..shutter speed value gives 1/60..Picture taken correct exposure..
B) When in Av mode + flash mounted..ISO fixed at 200, Aperture fixed at f4..same lighting, same scene as case A..
Question: Camera will return the same speed as case A for case B at 1/60? or adjusted (say, 1/125) to suit the flash power? Exposure compensation for camera and flash is at 0EV..
