I'm just starting to get used to the world of Micro 4/3, and this forum has been so helpful in aiding my transition. Having used APSC and FF DSLRs for 4-5 years, I'm familiar with the basics, but some of the things aren't quite the same between DSLRs and Micro 4/3. One of these things is off-camera flash. I used RF-602s and Comtrig T320s with my D700 and 5D, and they worked great with my SB-24s off-camera. However, I've discovered a quirk when trying to use these triggers on Micro 4/3. I've tried the triggers on an E-PM1 and an E-PM2, and on both of these cameras, the flash triggering seems to be intermittent. What I mean is this: I'll put the trigger on the hotshoe, turn on the trigger/receiver/SB-24, turn on the camera, and then take a shot. The flash will always fire, but the first 1-2 shots will come out dark, as though the flashes didn't quite sync up with the camera. Afterwards, if I take more shots, they will be lit correctly. If I don't fire the flashes for a while and then take another series of shots, the first 1-2 shots will come out dark again, with the ones afterwards being lit correctly. I've tried many different shutter speeds, setting first/second curtain sync, and even taping up all of the contacts on the transmitter except for the firing contact, but nothing I've tried so far seems to cure this problem. It's something that I've never seen happen on a DSLR, so I'm a bit confused as to what might be causing it. Anyone have ideas?
