I need a bit of help/advice.
I have a Canon 7D and last night I did a night shoot, and realised the AF assist beam was not working on both my camera and 580EXII flash.
I had a look at both the flash custom funtion settings and the camera custom function settings and they are both on.
Any idea if there is another way to turn it on or is there something wrong with the camera.
Needless to say I had a horrid time focusing last night and had to use a torch to get shots in focus.
