Hi just got my first flash last night a Canon Speedlight 580EXII, does anyone have tips on usage? Here is what I found:
On full Auto (green zone) works fine just like a high power point and push.
ISO for following: 800
On P mode, also works OK allowing for a little more control.
On Av – very difficult. It seems the camera still exposes for the ambient light, so flash fires but the shutter stays open for quite a while (depending on level ambient light)
If I set flash exposure by pressing the FELock ( * on my EOS 400D) then it seems to be a bit better.
On TV can set a shutter speed (indoors) of around 1/60 – 1/80 works Ok, aperture sets about f5.8
On M seems best typically around an F5.6 and shutter as above, but does allow my to vary apature a stop or so with acceptable results.
Any hints on how to get best exposure, I have 24-70 f2.8 and 70-200 f2.8.
The zoom setting only works when firing flash straight on, so when bouncing I guess it’s just a matter of trail and error to get to know how the results will turn out?
