This exciting new addition to the EOSSystem combines compact size and affordability with an added dose of featuresand sophistication. Improving on the previous model, Speedlite 420EX, the new430EX can now be set into manual flash mode (full power~1/64). Flashcompensation can be set on the flash unit, and manual control of the flash zoomhead is now possible. Improvements in its circuitry make recycle time 40%faster, and since it is compatible with Canon\'s wireless E-TTL, it can be usedas an affordable "slave unit."
