Sigma announces EF-530 DG SUPER & ST flash units

Canon Flash Speedlite 220EX
When in E-TTL operation, flash exposure is measured and controlled by the camera in combination with Canon's AIM system. Subject position, ambient light level, evaluative metering and pre-flash data are instantly analyzed, including heavy backlighting or reflections from background windows or mirrors.
Designed for automatic operation only, the 220EX Flash Unit excels at providing natural-looking balanced flash exposures. When attached to the EOS IX, EOS Elan II/Elan IIe/IIe, or EOS Rebel G, the 220EX incorporates the superior technology of Canon's unique E-TTL evaluative pre-stored flash exposure control system, FE Lock for a new dimension of creative control and FP Flash(High Speed Sync) for flash photography up to maximum shutter speed. When used with other EOS cameras, or the T90, it operates as a TTL autoflash (off-the-film flash metering).
Canon Flash Speedlite 430EX
This exciting new addition to the EOS System combines compact size and affordability with an added dose of features and sophistication. Improving on the previous model, Speedlite 420EX, the new 430EX can now be set into manual flash mode (full power~1/64). Flash compensation can be set on the flash unit, and manual control of the flash zoom head is now possible. Improvements in its circuitry make recycle time 40% faster, and since it is compatible with Canon's wireless E-TTL, it can be used as an affordable "slave unit."

Canon Flash Speedlite 580EX II
Further development of Canon's flagship Speedlite has led to the production of 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.
