What batteries do you use? NiMH's like eneloops recycle the flash significantly faster than alkalines (2-3 times as fast).




I am using Energizer Recharable, so the eneloops will give mequicker fire power?


I did notice that the 430ex, I used it off camera remote at the bird feeder last week and I could get several shots with it. It seems to have a better recycle time than the 580ex II. But I can tell that the 430 doesn't throw as much light as the 580. This was important yesterday, it was overcast and I had the 580ex at +1 and +2 several times trying to get enough light to fill.


I did order the better beamer yesterday to see if that helps.
