SB600 on E-P3 doesn't fire
The other day I stuck the SB600 on my E-P3 to do some bounce flash photography. All worked perfectly fine.
Now I am trying this again but the flash doesn't fire anymore.
The camera is set to manual with flash on full.
The flash is set to manual too, CLS (wireless) deactivated.
The flash fires when triggered on the unit.
I hope I am forgetting a setting???
