4. Operating Instructions
4.1 Power On/Off and Flash Levels
To power on the ZF08, long-press the power button. The flash offers five levels of adjustable output, ranging from 1/1 (full power) to 1/16. Short-press the flash level button to cycle through these power settings. The LED indicators on the flash will show the current power level. Long-press the power button again to turn off the device.
4.2 Test Flash
After powering on the flash, you can perform a test flash by short-pressing the power button. This allows you to verify the flash output before taking a photo.
4.3 Shutter Speed Synchronization
The ZF08 syncs with your camera's shutter. The flash sync speed is 1/200s. When shooting above the camera's maximum flash sync speed, black borders may appear in your photos. If this occurs, reduce the shutter speed by one stop until the black borders disappear.
4.4 Diffuser Usage
The ZF08 comes with a diffuser. Attach the diffuser to the flash head to soften the light output, which can be beneficial for portraits or reducing harsh shadows.
