I'm ignorant when it comes to flash photography as I hardly ever shoot w flash. On the very few occasions I use it I would want it off the camera. Not wanting to spend much money or add bulk, is there any way I can get my little FL-LM2 to work remotely off the EM-5? Any wireless capable thingy I can add to it or in worst case some sort of cable? If not, what is the smallest flash unit that can work remotely on EM-5? I don't need more power than FL-LM2 but just a bit more control of direction of light.
