Olympus Flash FL-900R

This powerful flash with its frost-proof (-10 °C), dust-proof and splash-proof design is particularly compact and lightweight. Combined with the weatherproof OM-D series cameras and M.ZUIKO PRO lenses, you can shoot in adverse conditions without any worries.
This flagship high-intensity flash has a maximum guide number of 58, and the combination of the camera's internal image processor (TruePic) and TTL sync technology ensures optimal lighting conditions for photo shoots.
Since the flash has a wireless flash firing mode, you can wirelessly control multiple flashes for high intensity shooting. You can control up to 4 groups of flashes and select which of the groups to fire. You can also set flash intensity correction values and adjust various settings. Another attractive feature is the slave function. You can simply attach the flash to a camera's hot shoe and use it as a master flash when using the control function.
Of course, the popular Olympus High Res. Shot, Focus Stacking and Focus Bracketing functions are also supported. Shorter shooting intervals are also available.
The FL-900R has an LED light for video, which allows OM-D videos to be recorded in low light or backlit conditions. Best suited for lenses with a focal length of at least 12 mm (24 mm).
