Hey just wondering if anyone knows what the difference is between the Canon 550EX and 420EX (flashguns)?
I heard that the 420EX has a faster cycle time... is that true?

i have the 580ex and the 420ex. I was going to buy the older and larger 550ex, but couldn't see a reason to spend $300 on a flash and not spend that last $50 to get the best.
I have found the 420ex to have OK recycling time if you are shooting one shot every once in a while (about 5 secs.) The 580ex for me recycles very fast, even without the external battery pack. also if you have a camera that doesn't allow you to use second curtin sync or flash exp .comp., the 550/580 lets you do these in flash.
of course YMMV

The 550 and 580 allow you to set the flash manually. That can be a HUGE advantage. There have been many times when I've wanted to throw my 420s against a wall because of the lack of manual exposure settings.

Is it that the 550EX has a max. guide number of 55 while the 420EX has a max. guide number of 42.
So the 550EX is more powerful, but also contains other features.
I use a Sigma EF-500. Which is supposed to have a few similar features to the 550EX

Speaking of 550EX I just got one for my Birthday a month ago, yet i still haven't had the chance to have a good play around with it (because of exams >_<). I found the cycle times abit slow, but it maybe just because i'm using dodgey batteries. I think it can be fixed by using those 2300mAh batteries.

update on the 550EX I just replaced the batteries with the 2300mAh rechargable batteries, and there is a HUGE difference. It cut down cycle times significantly.
