Hi, Have somebody here tried using the sunpak rd 2000 on olympus epm2 or any other m4/3 body? Is it compatible? Do they have olympus mount? Please advice me because i have plans to buy rd2000 for its size. Other flashes are way too big for my camera. My criteria for choosing flash are 1. Size- it should be small for travel and will look balanced on top of epm2 2. Bounce capability- i only bounce bonus if it can swivel sideways for portrait. But tilt bounce is enough for me. 3. Power- at least gn21 or much power as sb400. I will only use the flash mostly for indoor family gatherings.
