The dustproof, splashproof and freezeproof STF-8 Twin Flash is an extremely compact, lightweight macro flash system designed for shooting in all conditions.

Macro Flash Set STF-8



The STF-8 Twin Flash is the world's first weatherproof macro flash system, specially designed for capturing macro images in all types of conditions. With its compact and lightweight design, you can easily capture properly illuminated macro shots in any environment, even in the rain.


The STF-8 offers unparalleled macro lighting control. In addition to full TTL auto-sync, you can manually choose the output power, from full all the way down to 1/128. The flash ratio between the left and right heads is also fully adjustable from 1:8 to 8:1, so you’ll never feel limited in your ability to control highlights and shadows across your subject. The heads are removable: position one to light your subject, the other to light the background, or any combination you choose depending on the shooting scenario. This can be especially useful for wide-angle macro photography.

Use both flashes for a guide number of 8.5 or one flash for a guide number of 6. Or, for softer lighting, simply rotate the built-in diffusers in front of the flash heads.


The STF-8 boasts dust, splash and freezeproof construction that perfectly complements weatherproof OM-D camera bodies and compatible M.Zuiko lenses, enabling you to illuminate your macro subject in the harshest of conditions.


With Olympus’ RC (remote control) system, you have access to a variety of wireless flash options. Use the STF-8 as a master flash to trigger additional RC compatible flash units, as a slave in one of four independently controlled groups. Perfectly light your macro subject with the STF-8 while using additional RC compatible Olympus flash units to illuminate the background.

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 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.


The STF-8 Twin Flash is compatible with advanced features like Focus Stacking* and Focus Bracketing**, available on select OM-D and PEN camera bodies. Now you can easily create stunning, perfectly lit macro shots with incredible depth-of-field!

* Focus Stacking available with OM-D E-M1 and E-M1 Mark II camera bodies using M.Zuiko Digital ED 12-40mm F2.8 PRO, 60mm F2.8 Macro, and 30mm F3.5 Macro lenses.

** Focus Bracketing available with OM-D E-M1, E-M1 Mark II, E-M5 Mark II, and E-M10 Mark II camera bodies.

Excellent unit- highly recommended.

Compact, excellent exposure, very good ability to balance flash between heads. I have owned many macro flash systems from many manufacturers. This one works very well and is well built. The only potential downside is that the twin heads are tethered to the master. The Nikon R1 system is completely wireless and very reliable. However, the Nikon system does not allow for such quick changes in exposure. This system works well and is a must if you shoot macro with the OMD system

Flexible macro lighting

I do quite a bit of macro and close up photography and have tried many different lighting systems. The STF-8 twin flash is the most versatile on-camera lighting that I have used. It perfectly matches the 60mm macro lens and provides any number of options for direction and relative power. At the same time it is small and lightweight. The flash system is not as hard to assemble as it looks, and the included case packs the entire system for travel.
