Canon Speedlite 580EX II Flash

Canon's flagship Speedlite the 580 EX II.

This is the premier Speedlite for all photographers, including professionals.

Newly designed to match with the EOS-1D Mark III in terms of improved dust- and water-resistance, body strength, and the ability to control flash functions and settings from the camera menu (EOS-1D Mark III only).

Other features include improved communication reliability through its direct contacts, and recycling time is both 20% shorter than the 580EX and is completely inaudible.

	Approx. 20% faster recycling time compared to 580EX
	Superior build quality, including a metal foot for higher rigidity
	Max. Guide No. 58 at 105mm setting (GN 190, feet)
	Auto conversion of flash coverage with compatible digital SLR cameras
	White Balance info communicated instantly to compatible digital SLR cameras
	Full swivel, 180° in either direction
	AF-assist beam, compatible with all AiAF points on every EOS SLR
	Dust- and water- resistance to match the EOS-1D Mark III

• E-TTL II evaluative flash metering for critically accurate exposure
• High output with maximum guide number 58 at 105mm setting (ISO 100, metres)
• Autozoom and colour temperature information for improved flash with selected digital SLR cameras
• Fully featured wireless flash capability, with built-in slave and transmitter, using multiple Speedlites
• Dust and water resistance improves reliability under harsh conditions
• Metal mounting foot with new locking mechanism improves connection and communication reliability

• 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
