Hi all,


I am wondering if an upgrade from the 580 EX to the new 580 EXII with auto is worth it. As most of you probably know, using the 580 EX in ETTL mode can be somewhat tricky at times. I have done a lot of research and have found if used properly it works pretty good most of the time using manual settings,back button focus, selecting the proper focus point, and one shot mode.


I guess what I'm looking for is anyone who has used both and how well does the auto feature work, is it worth the upgrade?


I am shooting with 30D.


Thanks in advance to anyone who can advise.
