The Canon 580EX is an external flash unit, or "speedlite," that is used with Canon SLRs and other compatible cameras when the camera's built-in flash is inadequate for lighting a scene. External flash units allow for faster recycle times, more power, advanced controls and an overall better quality of light. The camera's E-TTL mode allows photographers to let the flash meter the scene at hand and take what it determines is the best possible picture.
Instructions
1. Attach the Canon 580EX to your camera's hot shoe. The hot shoe is located at the top of the camera and 580EX slides into place. Once connected, use the lock switch to lock it in place.
2. Power on both the camera and the 580EX. The ON/OFF switch is located on the back of the unit to the right.
3. Press the "Mode" button on the back of the flash until the display reads "E-TTL" in the upper left corner. E-TTL is the camera's automatic mode. All metering is done automatically and the camera selects what it determines are the best settings for the scene at hand.
4. Press the "C.Fn" to illuminate the 580EX's display when working in dim environments. Use the "Zoom" button to determine the angle of the spread of light if it doesn't automatically set itself. This usually corresponds with the zoom length of the lens in use.
5. Compose your picture and press the shutter release button. Wait for the "Pilot" indicator light or flash recharge light button to turn red to determine when the flash is ready to be used again.
