The FL-36R has a rotary head that can be rotated in four directions. The guide number is as high as 20 at 12mm (equivalent to 24mm with 35mm camera) and 36 at 42mm (equivalent to 84mm with 35mm camera), when the ISO is 100.
*The E3 is the only camera compatible with the Olympus Wireless RC Flash System as of October 2007. The traditional clip-on flash system is usable with any camera model.
