Sistema de Flash Canon
O Sistema de Flash Canon é um mecanismo de flash fotográfico utilizado pela Canon nas câmeras SLR seja de filme (35mm e APS) ou digital. Desde seu lançamento em 1987 até os dias de hoje, muitas revisões foram feitas, com a introdução de novos sistemas de exposição e medição.<!--The main technologies are known by the names "A-TTL", "E-TTL", and "E-TTL II".

These technologies involve both the EOS camera bodies and the flash units themselves, which are sold under the trade name of Speedlite (similar but not to be confused with Nikon Corporation's "Speedlight" brand for their flashes). The "Speedlite" name is also used by Ricoh for its unrelated product line of flash units, such as the Ricoh Speedlite 202. Both brand name spellings indicate that strobe flashes produce much shorter and more intense bursts of light than earlier photographic lighting systems, such as flashbulbs, or continuous lamps used in some studio situations.

The EOS flash system is capable of wireless multiple flash control, whereby a master flash unit or IR transmitter (ST-E2) mounted on the camera body can control up to 3 groups of flash units through infrared (IR) signals. The Canon EOS 7D is the first and (to date) only camera body to be able to control Speedlites wirelessly without the use of a Master Speedlite or IR transmitter.
