• Replaces the Canon Speedlite 420EX Flash
• Automatic selection of camera white-balance settings and auto-adjustment of zoom flash position to match camera's sensor size
• Flash head zoom covers the range 24mm to 105mm; integrated diffusion panel allows extends coverage to 14mm
• Compatible with distance-linked E-TTL II system; supports other EOS cameras that do not support E-TTL II, when required
• Flash head moves up from 0 to 90 degrees, left from 0 to 180 degrees, and right from 0 to 90 degrees

This exciting new addition to the EOS System combines compact size and affordability with an added dose of features and sophistication. Improving on the previous model, Speedlite 420EX, the new 430EX can now be set into manual flash mode (full power~1/64). Flash compensation can be set on the flash unit, and manual control of the flash zoom head 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 used as an affordable "slave unit".

so far so good i wish canon came up w/the buttons that is not sooooooooooo soft.sometime having hardtime presssing it.

well i didnt do much flash photography but i thought it would be nice to have so i got and i find that i use it all the time more than i ever thought i would its easy to use and has just enough options to be great for a amature but not confusing but also enough to make a pro happy

As a novice photographer, I was looking for a flash to accompany my Canon Rebel xti. This fit the bill. The cost was reasonable relative to other flashes, and gave me the simplicity I was looking for as someone still learning the 'craft' of photography. Well worth the money.

This flash is a good addd on if you have an EOS. It is small, portable/light which is a good thing. Larger and heavier flashes may put out more light when needed, or have faster recycle times, but this flash has worked fine for me.

It recycles fast enough (I have not missed a shot that I wanted because of the flash cycling too slowly) and it is fine for indoor use.

My flash went out on my cannon and I was back and forth on repairing it because it was cheaper to buy an external flash but I was concerned about the extra size of the flash but the pictures are way better now!!
