No, but I can see it, and logic dictates it. There isn't a fast lens in existence that is sharper wide open than stopped down a bit. Anyway, its not a pissing contest about two fine lenses is it?

I certainly hope it isn't.
I know my PLµ 25/1.4 very well while I haven't even seen a Panasonic 12-35/2.8. From the samples I've seen the zoom looks like a good performer. But that is about these web sized samples and most lenses look good...
I'm not sure logic says a zoom is better at f/2.8 that a good prime at f/1.4. Logic tells me most lenses are equal at f/4-f/5.6 just as the FF lenses all perform very similar at f/8-f/11 when used with a FF camera.
Anyway, I found the technical reviews of these lenses at SLRGear and no doubt the 12-35mm zoom is excellent. Unfortunately they were reviewed using different cameras so the extreme peeper in me isn't totally satisfied. Common sense however tells me the zoom will do fine for my needs.
Looking through the posts in this thread make me wonder if I should save up for the Zuiko M 75mm or the Panasonic 12-35 zoom first. The 75mm is tempting as well.
