E-TTL II Flash metering
Portable and compact, the Speedlite 580EX II is high powered with a Guide Number of 58 suitable for bounce flash and telephoto lens shooting. E-TTL II metering ensures accurate and consistent flash exposure in all situations.
For more control or creativity flash power can be set manually in 1/3rd stop increments from 1/1 to 1/128th power.

24-105mm auto zoom head
With a compatible EOS digital SLR, the Speedlite 580EX II automatically detects the sensor size and zooms for optimum coverage. This minimises wasted power and improves recycling times.
The 24-105mm auto zoom head and a 14mm wide-panel diffuser provides flash coverage for a wide range of shooting situations.
The 180degree swivel head and associated tilt settings allow the option of bounce flash for softer lighting.

Wireless Master or Slave
The 580EX II will act as a remote mater flash to trigger up to three groups of slave EX-Series Speedlites. With either E-TTL or manual flash exposure control you can create a portable lighting studio for complex lighting setups.

Colour temperature transmission
Combined with a compatible digital SLR, the Speedlite 580EX II will transmit white balance information to the camera to ensure accurate white balance at all times.

Stroboscopic flash
Use stroboscopic flash for creative motion photography. Stroboscopic flash functions with just one 580EX II or in a multiple flash setup of several Speedlites. Set the flash frequency between 1-199Hz for the effect required.

Power source
Powered by 4xAA batteries or external power supplies like the CP-E4, the Speedlite 580EX II is lightweight and powerful. The recycling time with AA batteries is nearly silent and takes less than 2 seconds for a full-power flash.

Weather sealing and durability
Complete weather and dust sealing ensure the flash will continue working in harsh environments. Coupled with a metal mounting foot and quick release latch, the connection between the camera and Speedlite is easy to use and secure.

Flash control
When used with a compatible camera all aspects of flash control, including flash power, wireless flash and all 14 custom functions can be adjusted from the camera menu.

AF Assist
Compatible with all EOS cameras, the Speedlite 580EX II can emit a focusing beam providing contrast for the lens to focus on when shooting in low light.
