It features a powerful guide number of 58 meters at ISO 100, providing ample illumination for a wide range of shooting scenarios.

The unit is equipped with a zoom flash head that covers focal lengths from 24mm to 105mm, with an integrated wide panel extending coverage to 14mm, making it versatile for different lens configurations. It also includes a bounce and swivel head, allowing for flexible light direction to achieve various creative effects and reduce harsh shadows.

The 580EX is compatible with Canon's wireless flash system, enabling it to function as a master or slave unit in multi-flash setups. This capability allows photographers to experiment with off-camera lighting for more dynamic and professional results. The flash provides fast recycling times, typically ranging from 0.1 to 6 seconds, depending on the battery type used, ensuring readiness for rapid shooting conditions.

Additionally, the unit features a high-speed sync mode, which allows flash synchronization with shutter speeds exceeding the camera's standard flash sync limit. This is particularly beneficial for outdoor portraits and action shots where control over depth of field and motion blur is critical. The Canon Speedlite 580EX is powered by four AA batteries and offers a user-friendly interface with a backlit LCD panel for easy navigation and setting adjustments in various lighting conditions.
