One area where Micro Four Thirds users have been seriously neglected is in radio TTL remote flash capability.
A big player in third party radio TTL remote flash technology is PocketWizard who have had their FlexTT5 units available in either Canon, Nikon or Sony versions for several years now.
This week PocketWizard have announced a Micro Four Thirds version – albeit at this stage only compatible with Panasonic GH4 camera in combination with either a Panasonic DMW-FL360L or DMW-FL580L flash but will support radio remote HSS TTL as well as normal remote radio TTL mode and their proprietary Hypersync non-TTL mode.
These units thankfully are firmware upgradeable, and they do intend adding support for other cameras and flashes, and there is no physical reason why this could not be extended to Olympus cameras and flashes given they use the same hotshoe pins (although Olympus has an additional power supply pin now which would be ignored by this units without issue) and essentially the same TTL technologies.
The units will cost $US186 per unit or $US299 for a pair (you need one for the camera and a receiver for the flash).
