The Speedlite 430EX flash unit replaces the popular Speedlite 420EX. The Speedlite 430EX improves on many specifications of its predecessor and includes new features to maximize digital image quality when using a flash. These include automatic selection of camera white-balance settings and auto-adjustment of the zoom flash position to match the sensor size of the camera to which the unit is attached. The Speedlite 430EX has increased its guide number to 43 (m/ISO 100 at 105mm) and has approximately 40% faster recycling time than the Speedlite 420EX.
An ultra-bright, two-LED configuration focus assist-beam has been designed to be compatible with all focus points within the frame of all EOS AF systems, up to 9-point AF.

The flash head zoom covers the range 24mm to 105mm and an integrated diffusion panel allows extended wide-angle coverage to 14mm.

Customer Feedback :
I added this flash to act as a slave to my 580ex in certain situations. This flash is phenomenal!!! The output is dead on and the exposure it gives is perfect, thanks to the ETTL-II that the 420ex lacked. Even when it’s connected to the shoe mount on the camera it’s awesome. The light weight is very much appreciated as I now tend to shoot with this as a walk around flash. Highly recommended as a backup or main flash unit!!
