From the Manufacturer

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.

Optimum flash coverage
The flash head zoom covers the range 24mm to 105mm and an integrated diffusion panel allows extended wide-angle coverage to 14mm. When attached to digital EOS cameras with smaller than full-frame sensors (such as the EOS-1D Mark II N and EOS 20D) the Speedlite 430EX gives a more accurate flash coverage by detecting the model to which it is attached and automatically narrowing the angle of coverage. This has the effect of eliminating light loss in peripheral areas and extending the effective flash range.

Ideal white balance
The Speedlite 430EX automatically transfers color temperature information to recent models of digital SLR cameras . The camera then sets the white balance optimally for the flash shot. This feature works when the camera's white balance mode is set to Auto White Balance (AWB) or Flash white balance mode.

The Speedlite 430EX is fully compatible with the distance linked E-TTL II system found on recent EOS cameras, and supports other EOS cameras that do not support E-TTL II, when required. For a complete multiple flash system, the Speedlite 430EX serves as a wireless slave when either the Speedlite 580EX, Macro Ring Lite MR-14EX, Macro Twin Lite MT-24EX, or Speedlite Transmitter ST-E2 is used as a master.

Upgrade for control
An intuitive and ergonomic interface includes an LCD panel for clear indication of modes and settings. A single bounce lock release button provides immediate control over the bounce head angle for flexible positioning of the flash head. The flash head can be moved up from 0 to 90 degrees (5 settings), left from 0 to 180 degrees (7 settings), and right from 0 to 90 degrees (4 settings). Six custom functions allow customization of the flash operations. Despite high power and short recycling times, the unit is small and lightweight.

Fully synchronized
Features include 1st and 2nd curtain flash synchronization, plus manual adjustment of flash output from full to 1/64 power (7 levels).

An optional Speedlite Bracket SB-E1 (not included--must be purchased separately) allows the flash unit to be mounted to one side of the camera. Designed specifically for press and wedding photographers, it eliminates the red-eye that can occur when mounting a flash on the axis of the lens, such as on the camera hot shoe. Flash batteries are replaceable without removing the unit from the bracket.

This was the very first flash I brought on the way to becoming a professional wedding photographer. Flash forward a few years, became a professional photographer and discovered this is the least used item in my bag.

I don't want to rate it low base on it's performance, because the little flash packs a punch. No complaints there. The best thing to do is decided on your use for it.

If you're just using the flash in the same manner as you do a walk-about lens - great for the everyday photo - you'll be more than satisfied with this flash. It's smaller than the 580EX II and more travel friendly.

Unfortunately, for professonal work, it's limited in that it cannot be used as a master, only a slave. The programmable options are limited because of this, so if I use it at all, it's generally to attach a color gel and position it off in the corner somewhere for mood lighting. If you plan to get really creative with multiple flashes and want to be able to be able to control the settings from the flash, this one is not for you.

But, if you want an excellent upgrade from your on camera flash and to deliever professonal flash quality this is a great buy for every day, low-pressure, high outcome use.

I am a real estate broker, so I always take wide angle interior photos with my 11mm lens. The lens is so big that the regular flash on my canon camera would always leave a dark spot on the lower part of every photo. I would have to use Photoshop to fix each photo ( what a pain )
I did a lot of research and found that all I really needed was the Canon 430 speedlite Flash... What a difference !
There is a lot of talk about "slave" or "master" flash or being able to put multiple flashes together.... all I can say is that this lights up every room in every house and it's perfect for my semi - professional needs.
Oh, the best part is that I got it used, and save a ton of money !

I love this flash. I'm an amateur photographer that shoots with a Canon 30D. I'm often taking indoor photos of family. When I first started shopping for a flash I was concerned it would not improve my photos enough to justify the cost. After learning how to take advantage of the flash my dim-light photos have greatly improved. The flash was a great buy. I never shoot indoors without it.

The 430EX is a good first flash since the 220EX does not allow you to swivel for bounce flashes, which for my skill level produces the best results, and the 580EX is overkill. Later if you get into flash photography you can buy the 580EX and use your 430EX as a slave flash.

I have found effectively using the flash does require a little practice. I encouraged my Mom to buy a 430EX for her Rebel and she was intially disappointed until I showed her the tricks I'd found or read about. The most important thing is to not point the flash at the target, point it at the ceiling or other surface and let the light bounce on to the target. This makes the light a lot more natural. The second trick was using custom function 3 on the camera to prevent overexposure of the subject. The last trick was to fire the preflash before taking the picture. Canon's TTL system fires a quick flash to meter the scene and determine how bright the actual flash needs to be before firing the actual flash to take the shot. I was trying to take shots of my eight-month old son smiling and his expression in the photo was slightly less happy than when I took the picture. Turns out he was reacting to the preflash quickly enough to subtly change his expression. Once I read the manual and figured out how to fire the preflash in advance (The * button on my camera) I was able to capture his natural smile.

Finally, flashes perform best with rechargable batteries. Apparently standard batteries increase resistance as they are discharged which increases flash warmup time. I've definitely noticed this with my flash. My next photography purchase is likely to be some "Ready-to-Use" Nickel Metal Hydride batteries (SANYO Eneloop 8 Pack AA NiMH Ready to Use Rechargeable Batteries) and a quality charger (La Crosse Technology BC-900 AlphaPower Battery Charger). "Ready-to-Use" is important because the batteries will not lose their charge over time and I don't want to worry about dead batteries if I haven't used the flash in a while.

I've also found the flash is great for catching high-speed events like someone throwing a ball, but this is an area I'm just now experimenting with.
