mr. homerJ. try this. hold the a55 up, look thru the evf. first thing you'll notice is that the colours are different from real. yep, my one and only experience with the a55 seems to indicate that user settings (like wb) are applied to the evf display. might be a good thing. then swing your body back and forth as if you were watching your child on a swing set. if you like the lag, and the very slow refresh that looks like a slide show, you'll be ok.
if, like me, that becomes a nogo, then you can look elsewhere.
