I admit I'm surprised that he rates the Oly 14-45 as good as the Lumix 20. I have both, and I don't think it's even close. I've essentially stopped using the zoom because I find the difference in quality so jarring.
Yes, I can say that I have stopped using zooms at all, at the moment, because I was always disappointed of the picture quality I obtained.
I've spent some time reading all Hogan's reviews, but I think that this time his thought is far from being clear or helpful for the reader. Usually he is very precise and lucid, I'm quite (negatively) surprised by this summary. Maybe he wrote in a hurry, I hope that in the next updates he will fix a it better what he's trying to say.
