I've been thinking about this for a while now. The 580ex II is a hell of a flash. I love it. But I don't use have the features since I always shoot in manual. But here are the things i do use that I like: Head swivel in all directions Quick recharge Almost NO sound while charging. But beyond that I might as well be using my 540. Here are the cons: Expensive (I already own it but could sell for almost what I paid) Doesnt work with my Cactus triggers More features than I need. So I dont know.. Is there a lesser flash that swivvles liek the 580? And recharges as quick?
