The Canon 580EX flash, replaced by the 580EX II in 2007, is Canon's flagship speedlight. The EX II recycles 20 percent faster than the original, has a better build quality, and an easier locking mechanism. The flash has a range of 30 meters and is dust and weather resistant.
Instructions
Getting Started
1. Open the battery door and install the four AA batteries, following the diagram for the proper polarity of each battery. Put the flash on the camera hot shoe and pull the switch to the right to lock it to the camera.
2. Turn on the flash and wait for the pilot light to cycle to green for Quick Flash and red for ready. Quick flash allows the flash to fire at 1/6 to 1/2 power for faster flash work.
3. Test fire the flash by pushing the pilot light. If it fires, wait for the flash pilot light to cycle back to red so that it is ready.
4. Turn on camera and turn the mode to Program, then choose your desired ISO setting. Push the Mode button on the flash until is displayed. Depress the shutter button on the camera halfway to focus on your subject, then depress the shutter button to take your photograph.
5. Check the flash exposure compensation light underneath the pilot light on the flash. If a proper exposure was obtained, this light will flash for three seconds. If it does not flash, move closer to your subject, recompose the shot, and take your photograph again.
