Query: Love my flash!

If you've never used a "real" flash before, this can be a bit intimidating, but overall I am very happy with the 580 EX II. After using a vivitar flash for a few years, I upgraded earlier this year and am glad I did. I love the control I have with this flash and after you use it a couple of times, all the settings become second nature. Going from a cheeper piece of equipment to one I can use TTL was like night and day. I definitely recommend just going for it and getting the good flash right from the start.
