3.2 Mounting on Camera
- Ensure both the camera and the flash unit are powered off.
- Slide the flash's hot shoe mount into your camera's hot shoe slot (refer to Figure 4).
- Tighten the locking ring on the flash unit to secure it firmly to the camera.
3.3 Wireless Trigger Setup (Optional)
The included wireless trigger allows for off-camera flash operation. Simply mount the trigger onto your camera's hot shoe and place the flash unit in a desired location. Ensure the flash is set to an optical slave mode (S1 or S2) for the trigger to function.
4. Operating Instructions
4.1 Powering On/Off
To power on the flash, slide the "ON/OFF" switch to the "ON" position. To power off, slide it to the "OFF" position.
4.2 Flash Modes
Press the "MODE" button to cycle through the available flash modes:
- M (Manual Mode): In this mode, you manually set the flash output power. This provides full control over the flash intensity.
- S1 (Optical Slave Mode 1): The flash will fire in response to the first flash from a master flash. This is ideal for cameras that do not pre-flash.
- S2 (Optical Slave Mode 2): The flash will ignore the first pre-flash from a master flash and fire on the second flash. This is suitable for cameras that use a pre-flash for red-eye reduction or TTL metering.
4.3 Adjusting Flash Output
In Manual (M) mode, use the "+" and "-" buttons to adjust the flash output power. The power can be set from 1/128 (lowest) to full power (1/1). The current power level is indicated on the control panel.
4.4 Test Flash
Press the "TEST" button to fire a test flash. This allows you to check the flash output and coverage before taking a photo.
4.5 Using the Reflection Board and Diffuser
The flash head includes a pull-out reflection board and a wide-angle diffuser. Pull out the reflection board to create a catchlight in your subject's eyes. Pull out the wide-angle diffuser to soften the light and achieve broader coverage, especially useful for wide-angle lenses.
4.6 Flash Sync Speed
The GODOX TT520 II supports a maximum flash sync speed of 1/250s. Ensure your camera's shutter speed is set to 1/250s or slower when using the flash to avoid partial exposures.
5. Maintenance
- Cleaning: Use a soft, dry cloth to clean the flash unit. For stubborn dirt, a slightly damp cloth can be used, followed by a dry cloth. Do not use strong detergents or solvents.
- Battery Care: Remove batteries if the flash will not be used for an extended period to prevent leakage and damage.
