Canon Speedlite 430EX
-The Canon 430EX - Canon Speedlite 430 EX - takes the middle position among Canon's external flash units.
Canon Speedlite 430EX replaced Canon Speedlite 420EX in August 2005. The changes that distinguish the 430 EX from the 420 EX indicate that the flash appears already with an eye on Canon EOS digital cameras: the flash automatically recognizes the "crop" of the camera and makes appropriate corrections to the zoom, and also transmits data for the correct setting of the camera white balance ... Other notable differences are the larger lead number, 40% shorter reload time and manual control of the most tips. Oh yes: the Canon Speedlite 430EX also has an LCD screen that displays information about flash operation.
