VIDEO : Introducing Canon's Radio Remote Flash System

I've just made available this new video that introduces Canon's 600 EX-RT flash and ST-E3-RT flash controller. The new radio system is a significant departure so I explain the infrared history of Canon remote flash, where the new system is compatible and where it is not, and offer a comparison to the well known Pocket Wizard radio controllers for eTTL flash.
