FR-WR Wireless Flash Receiver
The FR-WR Flash Receiver enables wireless radio wave control of clip-on flash units like the Olympus FL-900R and mono-block studio strobes when paired with the Olympus FC-WR commander or FL-700WR wireless flash.* Radiowave communication triggers flashes at up to 30m (100 ft), even with obstructions. Two intuitive dials control group and channel settings while a flash ready tone can be switched on or off with the push of a button. Use with the FL-900R flash in order to maintain the same dustproof and splashproof capability of your weather sealed OM-D body and M.Zuiko Pro lenses.
