Canon Speedlite 580EX II Flash Gun

The Canon 580 EX II Speedlite improves upon the design of the renowned Speedlite 580EX. New features include dustproof, water-resistant performance on a par with Canon EOS-1D/1Ds series SLR cameras, the ability to change flash unit settings on the connected EOS camera, and a metal contact area for more reliable conduction. While the illumination and bounce angles are similar to the previous Speedlite 580EX, performance has been improved to better meet professional needs through a shorter and silent recycling, and an external flash metering function.

Main Features

• 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.

580EXII 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

• High-speed (FP) sync mode, Flash Exposure Bracketing (FEB) and Flash Exposure (FE) Lock.
• Built-in transmitter and receiver offering fully wireless automatic flash with up to three groups of multiple Speedlites that can be controlled from the 580EX II or optional Wireless Transmitter ST-E2.
• Manual flash output between 1/1 to 1/128 in 1/3 stop increments.
• Stroboscopic flash output between ¼ to 1/128 with frequency range of 1 to 199Hz.
• 14 Custom Functions with 32 settings permitting customisation of operation to personal preferences.
• Dust and water resistant system - Exterior seams and joints, window edges, moving parts and the control panel are sealed against dust and water.
• Silent recycling oscillation frequency is beyond the hearing ability of humans.
• External metering system work with the flash reflecting off the subject measured by the external metering system.

580 EXII Advanced Design

• Autozoom head covering a range of 24-105mm or as wide as 14mm with built-in wide panel engaged.
• Built-in AF-assist beam compatible with EOS multi-point AF systems including 45-point Area AF types.
• Fully swivelling head with stops at 60, 75, 90, 120, 150 and 180 degrees.
• Flexible bounce head with stops at 7 (down), 45, 60, 75 and 90 degrees.
• Built-in catchlight reflector allowing a catchlight to be added quickly and conveniently to portraits.
• Improved reliability with direct contacts with the new metal quick lock and quick release mounting foot, which improves connection and communication reliability.
