1. تركيب البطارية

The EF 500 DG Super Flash requires four AA-size batteries (alkaline or Ni-MH recommended). Open the battery compartment cover, insert the batteries according to the polarity indicators, and close the cover securely.

2. تركيب الكاميرا

Slide the flash unit onto your camera's hot shoe until it clicks into place. Secure it by rotating the locking mechanism (if present on your camera or flash) to prevent accidental detachment. Ensure the flash is compatible with your camera's mounting system (e.g., Canon E-TTL, Canon E-TTL II).

أوضاع التشغيل

The EF 500 DG Super Flash offers various operating modes for diverse photographic needs.

• TTL Automatic Flash Exposure Control: Enables full-automatic flash photography. This includes E-TTL II for Canon, S-TTL for Sigma, i-TTL for Nikon, ADI for Minolta, and P-TTL for Pentax cameras. The flash automatically adjusts output for correct exposure.
• فلاش يدوي: Allows manual setting of flash output at eight power levels, from full power down to 1/128. Use the control buttons to adjust the power level as displayed on the LCD panel.
• Wireless TTL Flash Photography: Supports wireless communication with compatible camera systems for off-camera flash control. Refer to your camera's manual for specific wireless setup instructions.
• Slave Flash Photography: The unit can function as a slave flash, triggered by another flash unit.
• FP Flash Photography (High-Speed Sync): Synchronizes the flash with high shutter speeds, allowing for flash photography even at speeds exceeding the camera's normal flash sync speed.
• Modeling Flash: Emits a series of low-power flashes to help visualize the light distribution and check for shadows before taking the actual shot.
• Multi-Pulse Flash: Allows for multiple flashes during a single exposure. The power setting can be reduced from 1/4 to 1/128 in six steps, and the pulse frequency can be set from 1 Hz to 199 Hz.

الضوابط والعرض

The flash unit features an LCD panel that displays current settings such as flash mode, zoom position, and exposure compensation. Control buttons allow for mode selection, power adjustment, and other functions. A flash-ready signal is visible in the camera's viewfinder when the flash is charged and ready to fire.

Bounce and Swivel Function

For creative lighting, the flash head can be adjusted:

• الإمالة: The flash head can be tilted 90 degrees upwards for bouncing light off ceilings and 7 degrees downward for close-up photography.
• قطب: The flash head can be swiveled 180 degrees to the left and 90 degrees to the right, allowing for bounce flash off side walls or for directing light in various directions.

Built-in Diffuser

The EF 500 DG Super includes a built-in diffuser. Pull out the diffuser panel to expand the angle of illumination, covering a focal length equivalent to a 17mm lens. This is useful for softening light and covering wider angles.
