Combining the strengths of its predecessor 550EX while providing additional functions at higher speeds, the SPEEDLITE 580EX is Canon’s new flagship flash unit featuring a higher maximum guide number, shorter recycle time, autozoom control for image sensor size, and design improvements for easier handling by digital SLR users ranging from professional to advanced amateur.

Fully E-TTL compatible, and reverts to standard TTL operation when used on older EOS bodies or the T90. The fully swiveling bounce head zooms automatically over a range of 24mm-105mm. Wireless E-TTL compatibility permits it to function as a "slave" unit, triggered by a 550EX; ST-E2, or MR-14EX. Any number of 420EX and 550EX Speedlites can be combined as "slave" units. Guide Number 42/138 at ISO 100 - meters/feet @ 105mm setting.

E-TTL preflash autoflash system provides autoflash, FE Lock, FP flash (High Speed Sync.). Simplified, lightweight, compact design. Hot-shoe lock with a single motion. Flash confirmation lamp (after firing). Developed primarily for the EOS IX, EOS ELANII/ELANIIE & EOS Rebel G. Guide Number 22/72 at ISO 100 - meters/feet.

Twin-head macro flash unit, for directional lighting in close-up photography with full E-TTL automatic flash control (including with Digital EOS SLR bodies).

Each head can be rotated around lens in an 80° arc, swiveled inward or outward over a 90° arc, and swiveled up and down over a 90° arc. Each head is removable, and has both a standard shoe-mount and 1/4-20 female tripod socket at the base to facilitate mounting off-camera.

Powerful guide number (24/72 meters/feet) allows smaller apertures and greater depth-of-field when necessary. Incandescent focusing lamps, and two different types of 1-second modeling flash allow easy focusing and previewing of lighting effects.

The latest version of the Canon Data Verification Kit is designed to deliver validation of an unmodified original image from a single camera body, being able to detect a single bit discrepancy.

The new kit is much smaller than the old and uses a unique SM (secure mobile) card which is the same size as a Secure Digital card. The card reader connects to a computer USB port (only Windows 2000/XP compatible at the moment), drawing the power from the same USB port.

This kit is aimed at law enforcement, insurance, news and other such agencies and can detect single bit discrepancy in modification of an image since it was taken. Canon is applying for ISO 15408 certification (evaluation criteria for IT security) for the Data Verification Kit to further validate its application. The acquisition of ISO 15408 certification will give international recognition to the originality of images.
