I'm considering this flash as it seems a good compromise of size, features, and price. I've read several threads on this flash with various M43 cameras, but didn't find anything specific to the OM-D, and also I want to make sure that: It does AF-assist (very important to me, maybe even more than the actual exposure). Also, how does this work exactly? Is it a series of small flashes? Is it a constant beam? Is it annoying for the subject? It isn't too top-heavy with this camera Wireless TTL really works, especially with the on-camera flash NOT flashing at all I usually shoot my OM-D with the new Panasonic 12-35mm F2.8, but sometime with the kit 12-50. Thanks!
