The STF-22 Twin Flash Set employs two flash heads that allow versatile lighting for macro photography. Shading and depth of your subject can be enhanced by varying the firing angles, positions and Twin Flash light ratio of the two flash lamps. There's also the choice to use just one of the two flash lamps.

• When using both flashes, you can adjust the ratio between their light intensities as required.
• Diffuser enables shooting under soft lighting by attenuating the shades on the subject.
• Flash units can be take off the shoe ring and mounted on tripods for off camera lighting.
