Hello again, Could you guys help me out with my flash dilemma, please? I need two Flash guns, mainly for outdoor off-camera use (E-M1) - TTL isn't priority - Wrieless/radio connection instead of optical(line of sight) - Full manual control preferably including zoom - Anything above Gn40 goes - HSS/HSS Sympathy is important as well - Portability, if possible there should be one controller/transceiver that talks directly to the flashes Here's what I came up with so far: Option A: 1 x Yongnuo YN560-TX 2 x Yongnuo YN560 III Pros: only 3 units, cheap, full manual wireless control Cons: bulk, no HSS (up to 1/500 if I'm not mistaken) Option B 1 x Cactus V6 2 x Yongnuo YN-568EX II (This could be Metz here, but it's more expensive) Pros: only 3 units, HSS Sympathy (I don't understand that completely), slimmer controller Cons: more expensive, smaller display, no zoom control Option C 1 x Cactus V6 2 x Cactus RF60 Pros: only 3 units, HSS Sympathy, slimmer controller, full manual control Cons: even more expensive, smaller display Could you please help me understand the HSS Sympathy of the V6? How fast could the YN560-TX+YN560 III go? Does YN560-TX work with YN-568EX II without additional receivers, it should, the Cactus does, right? What other flashes/controllers should I consider? Also, feel free to correct me if I've made a mistake in the above mess. Thanks! I just discovered the Lighting Forum, could someone move the thread please, I'm sorry.
