For my main (m43) system I already have a host of manual flashes, used mainly off-camera with Cactus triggers, but I'd also like a small flash for the Fuji with TTL capability. Ι was looking into either the Fujifilm EF-42 or the new Nissin i40. Any experiences and suggestions about these flashes? Furthermore, because I'll never really use the flash on-camera, I'll need a cable capable of passing TTL info to the flash. I've found a couple of them on ebay, but I'd appreciate any suggestions on compatible items. Thanks!
