Bringing a new level of versatility and
capability to flash photography, the Speedlite 430EX II
features a powerful flash (guide number of 141 ft./43m at ISO
100) with a fast recycling time in a compact, durable body. A
one-touch quick-lock mechanism makes it easy to attach or
detach the 430EX II from the camera and a metal foot has been
added for strength and durability.
Flash controls can now be set through the camera's LCD screen
on compatible EOS Digital SLR cameras. The Speedlite 430EX II
is also quieter, recycle time is 20% faster (as compared to
the 430EX) and since it is compatible with Canon's wireless E-TTL,
it can be used as an affordable "slave unit".
