The FL-700WR from Olympus is a powerful electronic flash with a guide number of 42 meters at ISO 100 that covers a wide range of focal lengths with an electronic zoom head and built-in wide panel for wider focal length lenses. Fully compatible with Olympus TTL, it features IPX 1-rated weather resistance to match the same level of sealing as Olympus high-end mirrorless cameras. Also featured is a built-in one-touch on/off 1.5w LED light with a maximum output of 100 lux at 1 metre for constant illumination, perfect for video or use as a focus assist light when shooting stills. The flash heads design permits up to 90° upward tilt and 180° rotation in both directions for full bounce flash control. Rear dials and an LCD screen make operation a breeze, and it accepts four AA batteries as its power source. Integrated Wireless Radiowave functionality allows the FL-700WR to act as a flash commander or receiver with up to 3 channels of unlimited flash units that can be fully synchronized for lighting setups at a distance of 30m, with no line-of-sight required. When paired with the OM-D E-M1X or E-M1 Mark II camera body, the flash is capable of firing continuously at 10 frames per second for 50 shots at 1/16 power and state-of-the-art charging circuitry enables the FL-700WR to recycle in just 1.5 seconds (when using NiMH batteries, 2.5 seconds with alkaline batteries) when shooting sequentially. Multi Mode1,3 allows you to capture movement in your photos, by firing the flash multiple times during one exposure.
