So I just received my brand new 580EXII and this made me open my mounth as wide as I could. What a difference! I took some shots with it, just testing as I have no bloody clue yet what I am doing so it is all automatic, but the difference is so clear []


I am ecstatic!


Question:


What batteries do you use with it, where do you get it and how long will they last? I just got regular lithium batteries and have a feeling they will not last for long. Any advice?
