Modes de funcionament
The SFD926N offers several operating modes:
- i-TTL (Through-The-Lens) Mode: This is the primary automatic exposure mode for Nikon cameras. The flash communicates with the camera to determine the optimal flash output. Ensure the flash is set to "ETTL" (or similar auto mode) and mounted on the camera's hot shoe.
- Mode manual (M): Allows you to manually set the flash power output. Use the control buttons to adjust the power level (e.g., 1/1, 1/2, 1/4, etc.). This mode is useful for consistent lighting in studio setups or when off-camera.
- Slave Mode (S): The flash can be triggered wirelessly by another flash unit. Set the flash to "S" (Slave) mode. When another flash fires, the SFD926N will detect the light and fire simultaneously. This is useful for multi-flash setups without cables.
Adjusting Flash Head
The flash head can be adjusted for bounce flash photography:
- Inclinació: The flash head can tilt upwards from 0° to 90°. This allows you to bounce light off ceilings for softer illumination.
- Girar: The flash head can swivel horizontally from 0° to 270°. This allows you to bounce light off walls or adjust the direction of light when the flash is mounted on the camera.
Built-in Diffuser and Reflector Panel
- Difusor de gran angular: Pull out the wide-angle diffuser panel from the flash head to spread the light for wider lens coverage.
- Reflector Panel: Pull out the white reflector card from the flash head to create a catchlight in the subject's eyes or to provide a subtle fill light when bouncing the flash.
Synchronization Features

- Front Curtain Synchronization: The flash fires immediately after the shutter opens. This is the standard flash mode.
- Rear Curtain Synchronization: The flash fires just before the shutter closes. This creates a natural-looking trail of light behind moving subjects. Refer to your camera's manual for activating rear curtain sync.
