Movable flash heads

The angle of the flash heads can be adjusted in a range of 60° upward to 40° downward, and the position of the flash heads along the ring adapter can be adjusted as well. Arrange the flashes to create shadows and achieve your desired level of depth in your photos.

Output ratio control

The output ratio can be controlled from 1:8 to 8:1 between the left and right flash heads. Use the dial for quick output ratio adjustment.

Dedicated diffuser for soft lighting

A dedicated diffuser is included for creating soft lighting effects. The diffuser is designed so that you can select to use or not use it without having to attach or remove it every time.

Designed with working distance in mind

The flash heads are nearly even with the end of the lens for minimal effects on the lens working distance.

Delivering more versatile photography

Focus Stacking/Focus Bracketing compatible

The STF-8 can be used with popular features on the OM-D E-M1 Mark II, such as Focus Stacking and Focus Bracketing.

  • Manual flash only

Freedom in lighting

The flash heads can be removed from the ring adapter for further freedom in lighting. For example, keep one flash on the ring adapter to light the subject, and remove the other to use for background lighting.

Wireless control

This flash unit is compatible with the wireless flash control. It can be used as the commander flash during multiple-flash photography.

Macro photography with a wide-angle lens

The STF-8 is useful in wide-angle macro photography that incorporates backgrounds into a close-up shot. Use this flash unit together with a fisheye lens or super-wide angle lens for a new style of close-ups.

  • A separately available third-party bracket may be required depending on the lens.
