Canon Speedlite 220EX for Canon EOS SLR Cameras - Old Version
Featuring a recycle time of 0.1 to 4.5 seconds, the Canon Speedlite  220EX is a fully automatic flash, compatible with all Canon EOS cameras. The  220EX can also utilize E-TTL operation when paired with the Canon EOS IX, EOS  ELAN II/IIE, and EOS Rebel G. Sporting a save-energy feature, whereby the flash  is shut down after 90 seconds of idle, the 220EX is powered by four AA  batteries, and has a flash capacity between 250 and 1,700. The convenience and  ease of use ensure the 220EX a place in the hands of amateur photographers who  want a high-quality flash, but aren't interested in learning to use the  professional features of Canon's other offerings.
