Excerpt: This flash was used at Wedding rehearsal and was going to use it at the rehearsal; ;however my batteries expired. I would like to see the same battery that they use in the 5D camera used in the flash. I was using this as fill flash. When it worked I was satisfied.
Pros: Consistent Output, Easy To Use, Fast Recycling, Versatile
Excerpt: All the flashes work well but when will Canon develope a product thats truely intergrated? I want a flash that can be powered from the camera grip. I don't think thats too much to ask for considering the technicle capabilities of Canon. Or is there someting else I need to buy?
Pros: Good Exposure performance, Quiet, Superior build quality
Excerpt: For an $100 difference, it's so worth getting the 550. If it weren't for one particular problem (which I explain below), I'd say just get the 430 (unless you need to be in massive rooms and need the full power of the 550). Anyway, because of the problem, I absolutely recommend getting the 550.
Excerpt: I'm quite angry that I didn't reasearch this more, I could have saved myself [$]and gotten the 430EX I. I went with the 430EXII based on the specs here on Adorama, that said it rotated 180 both ways, which it doesn't. Otherwise, I really like it a lot.
Summary: Hi This is a good 430EX flash and cheaper to it's big brother the 580EX flash. I had the 420EX flash for a few years and has serve me well but I had found out about the 430EX flash, I decied to order one on the net with a few dollars off on the price. I found it was a big improvement on the 420EX flash it replaces "BIG"LCD screen that you can read information like, High speed sync, Custum Function, meter/feet reading, zoom and wide panel (14mm).
Pros: Big LDC screen, High speed sync, Manual, Flash exposure compension and slave., easy to use. Built in wide panel ( 14mm)
Cons: one things to say about the flash., 1: the metering on the LCD to measure the distance shows "m" like 9.0 m or 0.9 m meaning 9 meters or 90 cm it do make it less acuate when you are zooming the lens when you are trying to judge the distance. It would be good it they put in meters and centremeters/feet-inches this would help.
