6. Operating the Sunpak PZ 4000 AF Flash

6.1. Automatic Zoom Function

The PZ 4000 AF features a motorized zoom head that automatically adjusts its coverage to match the focal length of your lens, typically between 28mm and 80mm. This ensures optimal light distribution for your chosen lens.

6.2. Manual Zoom Control

If desired, the zoom head can be manually controlled. Refer to the flash's control panel and buttons to override the automatic setting and select a specific zoom position.

6.3. Flash Head Rotation

For creative lighting, the flash head can rotate up to 90 degrees. This allows you to bounce the flash off ceilings or walls, creating softer, more natural illumination and reducing harsh shadows.

The flash supports various modes, including TTL (Through-The-Lens) for automatic exposure control, Manual mode for precise power adjustments, and Fill-in mode for balancing ambient light with flash. Select the desired mode via the control panel.

6.5. Standby Mode

To conserve battery power, the PZ 4000 AF enters a standby mode if it is not fired for a few minutes. To reactivate the flash, lightly press the camera's shutter button, and the flash will quickly become ready to fire again.

6.6. Synchronization Speed

The flash supports a synchronization speed of up to 1/250 second, allowing for effective flash photography in various conditions.
