5.0 out of 5 stars
Nice design update. Works like a charm., December 4, 2006
The 430 is plenty of flash for many photographers. and makes a nice walkaround flash, backup, or outstanding slave flash for someone who gets bitten by the photo bug in a serious way. The only current flash model that can compete is the Canon 580EX, which costs about a hundred bucks more. Forget the Sigma flash. The 580 is a much better unit (I'll explain in a sec), but it is bigger, heavier, and again, more expensive. The 430 can do most of the important things a 580 can do that an amateur is likely to use, and then some.
Here are the important differences... The 430 is pretty powerful, but the 580 is much more powerful than the 430 (GN 58 vs GN 43 (meters)). That's a lot of extra reach, or extra bounce capacity. Again though, the 430 is plenty strong in it's own right. The 580 has a fun strobe feature that the 430 does not have. The 580 has much greater manual control than the 430, by virtue of being able to adjust it's output in double the number of increments compared to a 430. The 580 has 14 custom functions, while the 430 has 6. The 580 has an easier to use function wheel than the 430's "button wheel". The 580 head can rotate 180 degrees in either direction, and be set to less than 90 degrees to the lens axis, while the 430 can only rotate to 180 degrees in one direction, and cannot dip below 90 degrees to the lens axis. The 580 can control other 580's, and 430's as slaves via it's infrared optical control transmitter/reciever. The 580 covers all focus sensors on EOS cameras up to the 45 points used by the pro bodies. The 430 covers up to 9 sensors, which is fine until you get beyond the 5D body (the Rebel line, 10D, 20D, and 30D are fully covered). Both flashes include a pull out wide panel that will cover a lens as wide as 14mm on a full frame body, or as wide as 10mm on a 10,20,30D, or Rebel body, but the 580 also has a pull out "catchlight" panel designed to put sparkle in the subjects' eyes when using the flash in bounce mode. There are a few more things, but that should cover the big ones.
OK, the 580 is the knockout champion, so why did I rate the 430 with 5 stars? Because it deserves them. Canon was wise enough to pack very good power, and a FULL feature set into the 430 without screwing the prospective buyer by leaving out one or two important features that would force them to spend the extra bucks on a 580. The 430 is built well, looks sweet, works like the fine instrument it is, and is significantly smaller than the 580. The fact is, I use the 430 as my preferred flash more often than not. A trip to the car races, a birthday party, general photo fun, family stuf, etc. It is more flash than most people will ever need, at a good price. For those times that I need more, or want to use multiple flash units, the 580 heavy artillery is brought out, and the 430 becomes a second unit under the control of the 580. Both units come with a clever little "foot" that allows you to position them on any flat surface, so you can set up your scene lighting without having to use tripods to hold your slave flash units.
If the photo bug bites you, you will end up owning both flash units. Get the 430 first. If you never get into serious multi flash setups, the 430 will serve you just fine. I you do, you will end up buying it anyway :).
By the way, someone complained about cycle time on the 430. That was nonsense. Either it was a defective unit, or the reviewer was on the cheap, and used alkaline batteries. All flash units are very current hungry when they recharge after a full blast of light. Alkaline batteries are not capable of delivering high current levels more than a few times when they are new. Internal resistance builds up, and they begin to deliver such small current rates that you could sing an entire opera between flashes (no matter what brand of flash). Always use a high current technology battery like NiMH in a flash unit. You can buy a set of four 2700 MAh rechargeable batteries at WalMart for about seven bucks, or buy a brick of 24 of them online for about a buck each, and get a good charger for cheap too. With the right batteries, your 430 will recover from a full power flash in less than 4 seconds (about 2.5 in real life), and for less than full power shots (fill flash, etc.), you can take several shots in one second. Alkaline batteries will work in a pinch, but that is the only time you should use them. Lithium is a good technology for flash units too, but is still rather expensive. Buy NiMH for now.

Great flash!, December 10, 2005
I am a beginner to SLR flash photography, and I spent several weeks researching various flashes, both by online reviews, and by going down to the local camera shop with my Canon 350D (Rebel XT in US), and I finally decided on the 430EX over the Canon 420EX, Canon 580EX, and Sigma 500ST Super for a few reasons:
1. Manual Control- Not only does this give you the obvious ability to have more creative flexibility, but as a beginner, it gives you the opportunity to experiment, and practice the more technical skills of flash photography. Another benefit of manual mode is the ability to use opitcally triggered slave flash units in a multi-light setup. Fully automatic E-ttl mode flash will trigger the slaves with the metering preflash, and make using optical slaves impossible while using the onboard flash. (there are work arounds, but they involve reducing the output of the onboard flash to a minimal level by FEC or covering the flash with something, limiting your flexibilty in creating a lighting setup). This manual flexibilty was the primary reason I choose the 430EX over the 420EX.
2. Remarkable recycle times. I have no scientific data for this, just subjective feel. The 430EX out-performed the 420EX here. Not by a huge amount, but it was noticable. Under the same conditions-bounce for fill, low ambient light (meter read .3 sec at f4), the 430EX would be able to fire off an extra few shots in succession without having to wait for recycling. Depending on the battery level I could get 3 to 5 more partial power fill flashes in low ambient light, pressing the shutter release quickly with the 430EX over the 420EX. Again, not a huge difference, but noticeable.
3. Build quality was better than the Sigma. I use my camera a lot, in the most hostile of camera environments (I am an elementary school teacher) and it swings around and bangs into things, and gets swung around and banged into things...etc. The build quility compared to the Sigma isn't that different for a casual user, who will take pictures at home, or in a more controlled environment. In particular, the Sigma battery door felt weak. This wasn't a decision point for me, but it helped me lean towards my decision.
4. Finally, the last factor was the ability to function as a slave in a wireless setup that isn't optical. Optical slave setups are great for experimenting, and studio type setups, when you have the only camera in the room. But they do not work when every mother and father is taking a picture at the school play, and in the future, I plan to upgrade/expand to include infared control of a flash setup. Again, there are other options for non-optically controlled slaves, but the 580EX plus Canon slaves is an easy way for a non-pro like me to go.
For me, the primary selling point was manual control. I probably would have gotten the 580EX otherwise, and just might do so in the future if I can save my pennies. The Sigma 500ST Super was very tempting as well, and if you want a powerful flash, manual control, and don't plan to use a multi-flash setup, or you use an optically triggered setup, I would recommend that flash highly as well.
One last point, the AF assist on the Canon flashes will cover all the focus points on a 350D (Rebel XT), and 20D, whereas the Sigma will only illuminate the center AF reliably. This AF assist is much nicer than the built in flash assist, and has a reasonable range for most portraits and group shots in low light.
I hope this review helps you! It took me a long time and lots of research to decide, and hopefully, I have presented my reasons in an intelligible manner!
Have fun and take lots of pictures!

A Wonderful Backup!!!, October 30, 2005
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 awsome. The lighweight 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!!
