Canon Speedlite 580EX II Flashes Speedlites and Speedlights

Canon Speedlite 580EX II Flashes are powerful and efficient. E-TTL II flash metering utilising lens distance information with pre-flash to balances flash with ambient light for more evenly lit and natural looking photos even if the subject includes highly reflective objects.

High power flash output with maximum guide number of 58 at 105mm setting (ISO 100, metres)
Highly efficient power supply design providing up to 20% improvement in flash recycle time
Autozoom control with selected digital SLR cameras to automatically match the flash head to the effective focal length of the camera ensuring greater accuracy and optimal output
Colour temperature information transmission with selected digital SLR cameras ensuring optimal colour balance setting for flash output

Professional Features
