I have a 580EXII flash from my previous canon set up and the EM-5 is my first m43/Oly camera. I want to use the flash as an off camera set up, but not really sure what I would need. I have the wireless trigger for the 580EXII, the Canon ST-E2, but the sync of when I take a picture to when the trigger and flash fire, are almost over a second. I'm shooting at 1/60th but the flash is more like 1" and not really sure how to set the flash to fire faster in slave mode with the wireless trigger (guess this wont be possible with it being all canon gear?) Would the easiest way of getting off camera flash with this set up to buy a PC adaptor + cord? Something like this? Hama 6952 Flash Adapter Contact Cable: Amazon.co.uk: Camera & Photo Would the flash work in the same way as if it were mounted in this case? Any help on what I would need to buy to make it work would be great.
