Item #V326170BW000-U410-AF01

High-intensity, splashproof & dustproof FL-900R Electronic Flash boasts 58 meters at ISO 100 for wide range of focal lengths. Compliments all weatherproof OM-D bodies & M.Zuiko PRO lenses.




The high-intensity FL-900R boasts a guide number of 58 meters (at ISO 100) and covers a wide range of focal lengths with an electronic zoom head. A built-in wide panel enables you to use wider focal length lenses and have perfect coverage, and a catchlight panel illuminates your portrait subjects’ eyes effortlessly.


The FL-900R boasts dust and splashproof construction that perfectly complements weatherproof OM-D camera bodies and all M.Zuiko PRO lenses, enabling you to illuminate your subject in the harshest of weather. Dark and stormy conditions are no match for your complete OM-D system.


With Olympus’ RC (remote control) system, you have access to a variety of wireless flash options. Use the FL-900R as a master flash to trigger additional RC compatible flash units, as a slave in one of four independently controlled groups, or as a commander flash using the included IR filter.

Four available channels mean the RC Mode is resistant to interference from other photographers, so you can comfortably shoot events when other photographers are nearby.


The built-in 1.5w LED light in the FL-900R is a useful tool as both a continuous source for video shooting and as a focus assist light when shooting stills. One-touch on/off control lets you quickly access 100 Lux power (at 1m) when you find yourself in a low-light situation.


When paired with the OM-D E-M1 Mark II camera body, the FL-900R becomes a sequential shooting powerhouse. The flash fires continuously at 10 frames per second for 100 shots at 1/128 power or 30 times at 1/32 power! State-of-the-art charging circuitry enables the FL-900R to recycle in just 2.5 seconds when shooting sequentially, so you’re assured of getting the shot. An improved FP mode with expanded range lets you shoot beyond E-M1 Mark II’s sync speed without the worry of overexposure.

The new Multi Mode allows you to capture movement in your photos, by firing the flash multiple times during one exposure, further enhancing your creative control.

Sophisticated and Powerful

I upgraded from Olympus FL-600R, which is a decent flash. After a few first shots, I discover a big difference between these two flashes. For example, FL-900R almost never overexposes the shots, as FL-600R does. Even FL900-R is a lot more powerful. TTL, Wireless FLash, and other features work great with mine Olympus OM-D EM-1 Mark II. I used a lot of Canon, Sigma, and other manufacturers in the past and I must say that I'm very impressed with FL-900R abilities. Except for wireless flash. I'm used to having Master and Slave 2.4 GHz on the flash, unfortunately, FL-900R does not have such abilities. Overall, it is a fantastic flash, I would say the best for Micro Four Thirds.

Power and Speed

I have only had the fl-900R a couple of days so most of my observations are from testing rather than actual shooting conditions. On first impression it seems a bit big, and heavy, but it balances well on an E-M1, particularly with the grip. In fact it is only about 1/3 heavier than a FL-600R (about 17 ounces with NIMH batteries). The metal plate makes it feel quite secure on the camera. The flash has plenty of power to fill a normal room. It had no problems when bounced off the ceiling, with or without the included bounce adapter and worked well with third party flash modifiers. When zoomed to the 100mm setting it was able to light objects over 50 ft away. Recycle time is very short. That may be due in part to the power as it seldom has to use the full charge. Off camera it works well with either the FL-LM2 and the FL-600R. When used as a master the included IR filter does not seem to interfere with triggering an off-camera flash and should prevent the communication flashes from interfering with the setup. So far the FL-900R seems to be an exceptional flash: Powerful, fast, and well suited to the E-M1.
