Looking for an external flash for my canon 7D

[thach_le89]

Hello everyone, im looking for new external flash for my 7D.
i have idea about buying an external flash, i go online and find out some of them are suitable for me, they have 430EX II and another is 580EX II. The price is so different, 250 vs 450. So can anybody give me some advices and willing to explain the difference between those 2 flashes.
Thanks

If you are new to flash photography, get the 430ex I or II. Once you get comfortable with it, then go up the chain. The differences between the 430 & 580 are pretty much power, and more features, a bit better functionalities (metering).

Flashes last a long time unless really abused, save your money even further by buying them used here.
