Olympus FL-900R flash

The Olympus FL-900R flash is a high-performance flash with a dust, splash and frost (-10°C) resistant design and a compact, lightweight housing. When used with the OM-D series of weatherproof cameras and M.ZUIKO PRO lenses, harsh conditions are no longer a concern.
This highly efficient flash has a maximum aperture of 58 and the combination of the camera's built-in image processor (TruePic) and TTL sync technology allows for ideal lighting during shooting.
The flash includes a wireless flash mode, so you can take advantage of highly effective multi-flash shooting with wireless control, and manage up to four groups of flashes, choose whether to fire a group, correct flash power and adjust various settings. Another well-received addition is the slave flash function - you can attach the flash to the camera's flash hood and use it and the main flash simultaneously with the control function.
Olympus high-resolution shooting, sharpness stacking and focus shifting are of course also supported, and now shorter shooting intervals are available!
The FL-900R features a video LED light for shooting OM-D video in low light or backlit situations. Perfect lenses for lenses with a focal length of 12mm (24mm*) or more.
