The Canon Speedlite 430EX III-RT Flash allows you to enjoy many of the benefits of the flagship 600EX II-RT but in a smaller and lighter package. It improves on the 430EX II by adding radio transmission to the once infrared/optical-only triggering system. Radio transmission allows for easy transmitter/receiver communication between other 430 EX-RTs or with an ST-E3-RT Transmitter, even when the transmitter flashes and receiver flashes are not in line-of-sight of each other. The 430EX III-RT also boasts improved recycling time over prior models and features a handy Quick Flash Mode that allows you to interrupt the recycling time so that you can fire more quickly even before a full flash recharge. The Canon Speedlite 430EX III-RT Flash is ideal for portrait and product lighting while traveling as well as a great option for events.
