• Compatability
The Speedlite 580EX flash is compatible with Canon's E-TTL II (Evaluative Through The Lens) auto exposure technology. When combined with a compatible Canon camera (EOS-1D/s Mark II, Mark III, D-20, Elan 7N/E, or newer models) and compatible lens, E-TTL II utilizes subject distance and other information that automatically modifies flash power, resulting in accurate flash exposure regardless of subject size, reflectance, or photographic composition.
• Multiple Flash Exposure Modes
E-TTL II, E-TTL, TTL & Manual
• Faster Recycling Time
Improved power supply design provides up to 25% improvement in flash recycle time
• Built-in AF-assist beam compatible with EOS multi-point AF systems including 45-point Area AF types
• Built-in catchlight reflector allows a catchlight to be added quickly and conveniently to portraits
Professional Modes
• FE Lock - Flash exposure lock
• FP Mode, or high-speed sync, allows the camera to sync with flash at higher shutter speeds
• Second-curtain sync fires the flash at the end of the exposure, allowing streak of light to flow naturally behind the movement of the subject
• Wireless TTL flash when combined with ST-E2 Transmitter & multiple 550 EX's
• Stroboscopic mode shows several minute flashes continuously to easily view flash effect
• FEB - Flash Exposure Bracketing
• 14 Custom Functions that provide maximum control over various flash functions
• Ratio flash lighting of up to 8:1 when used with ST-E2 Transmitter & multiple 550 or 580EX's
• When color temperature data is automatically transmitted from the 580EX, the camera sets the color balance for the optimal flash shot
