I'm planning to get a hotshoe flash soon (I currently only have the onboard), and I have narrowed my choice down to several options, but I'm having a hard time deciding which way to go.
ETTL
This is probably the simpler option, and I think I would go ahead and buy the Canon Speedlite 580EX.
This would certainly work, but I have a limited budget, so I am considering a cheap (but decent quality) manual instead.
Manual
Mostly based on the lower cost, I am leaning towards these.
My Question
There are two parts to this... First, is there anything important I'm going to miss by going with a manual flash? From what I can tell it simply makes it easier to use it in auto settings.
Second, is there any significant difference between the LumoPro and the Vivitar? Both are inside my budget, but the price difference is significant, so I want to make sure there's not something I'm missing.
