so i never really thought i'd be getting a flash anytime soon, as i tend not to even use the on-board flash...but just picked up an old macro lens...and am realizing i need one, in order to try and take anything handheld with the small dof...so i know that i don't want to spend a ton of money...whats the difference between the 430EX, and 420EX...is it just recycling time/power?...bottom line is can i do most things with the 420EX that i could do with the 430EX?
thanks in advance
