本人想購入外閃
但想問430EX 跟 580EX 的分別係咩..
一般影人像 室內.. 室外補光.. 夜景 430EX 好嗎
還是一步到位?

差在GN POWER係43同58
如果要用係室外, 430一定唔夠

有錢就買580EX II

430EX = GN 43 at ISO 100 If you use f/4. Effective range = 43/4 = 10.75m
If you use f/8 Effective range = 43/8 = 5.37


580EX =GN 58 at ISO 100 if you use f/4. Effective range = 58/4 = 14.5m
if you use f/8 Effective range = 58/8 = 7.25m


You can see that 580 is poweful than 430 approx. 1.5 times in effective distance. If you use long zoom with flash. 430Ex may be not enough. But you can compensate by use larger aperature or increase the ISO.

If you have enough money. 580EX is much better and the weight different is not significant as well.
