Features

High-power flash with a guide number of 58

This high-power flash has a maximum guide number of 58. By combining the TruePic image processor and TTL synchronisation technology, optimal lighting is produced. It covers an illumination angle of 24-200mm and 14-20mm when using a wide panel.

10-fps sequential shooting tracking performance

The FL-900R has the highest sequential shooting tracking performance in its class[1] at 10 fps[2]. Charging circuits optimised for NiMH batteries reduce charging time to approximately 2.5 seconds. The firing range has also been expanded to low intensity levels for enhanced tracking performance during high-speed sequential shooting.

  • 1. When using a clip-on flash with a guide number of 50 or higher powered by four AA batteries. Based on Olympus research as of September 2016.
  • 2. When using the OM-D E-M1 Mark II, at a flash ratio of 1/32.

Compact, lightweight flash that is dustproof, splashproof and freezeproof down to -10℃

The FL-900R is compact and lightweight, making it highly portable. Additionally, since it is dustproof, splashproof and freezeproof down to -10°C like the OM-D E-M1 Mark II, E-M1, or E-M5 Mark II, using this flash with any of those cameras lets you shoot in a variety of severe environments.

Useful in all types of photography

Equipped with a commander function[1] for coordinating with wireless flash units

This flash unit can be used for multiple-high-power-flash photography via wireless control. From the camera, you can adjust settings for up to 4 flash groups. The flash also comes equipped with a slave function. In addition, the FL-900R can be attached to the hot shoe of a camera and can be used as the master flash when using the commander function. An IR filter is included for when the commander light is not necessary.

  • 1. A commander function-compatible camera is required.

Compatible with Multi Mode

This FL-900R is compatible with Multi Mode for firing the flash multiple times during long exposures or bulb shooting to express subject motion.

  • Compatible cameras: OM-D E-M1 Mark II (as of November 2016)
  • Caution: successive use of the flash on human subjects may affect their health.

Compatible with High Res Shot, Focus Stacking, and Focus Bracketing

This flash unit can be used with popular features on the OM-D E-M1 Mark II such as High Res Shot, Focus Stacking, and Focus Bracketing.

  • Manual flash only
