I would like to use my Nissin i60A flash as an off camera slave - but for it to fire when the flash on the camera fires.
I've set the dial to Sf. However when I take a picture, all I get is the Nissin giving me 6 or 7 beeps, the green light turns red and that's it.
So, am I doing something wrong or is this flashgun not capable of doing what I want?
Thanks for any advice
Alan
