Hi guys, I'm seeking a bit of advice. I waited many years for Canon to create a radio controlled Speedlite system, and no sooner than they finally delivered, I switched to Olympus. Unfortunately, not before buying and falling in love with the new RT system. I've grown especially fond of E-TTL remote controlled flash systems and I'm looking to buy a 3 light system for the E-M1. Reading over this write-up, it seems like if I'm going to stick with Olympus I need an FL-600R mounted on the camera to use as a commander if I want to stay with a faster flash sync (1/250). The FL-300R which I currently own only works in 1/60 if I'm reading this correctly, and the FL-50R cannot be used for 1/250 or as an RC master. I'm worried in outdoor situations, the included flash with the E-M1 won't be powerful enough to trigger the remote lights in bright sunlight if they're not very close to the camera. http://www.ayton.id.au/wiki/doku.php?id=photo:olympusomdem5_flashrc I currently have several flashes I can trigger remotely using full manual and a remote trigger, but the appeal to me is the E-TTL RC system. If I have to go full manual, I'd just assume take my studio lighting and light meter with me. Are there any 3rd party systems I should consider with full E-TTL support for the E-M1 that might be more powerful than the Olympus system? Multi-group support is a must, and I have to be able to control the output of each group from the camera / on-camera flash. Thanks in advance for any feedback on this.
