Hi Anthony, after 5d2 I was using the GF1 briefly before deciding to switch over to EP-2 & evf2. No doubt I like the form factor of the GF1, shooting manual lenses wasn't fast, neither was it that easy, usually requiring magnification to get the focus spot on (to clarify, I did not try the panny evf, i was told its crap!)... eventually what got me to adopt EP-2 or rather olympus, was simply the efficiency I could achieve shooting manual lenses using the EVF2 - fast and accurate without having to magnify! This marks the difference between capturing that impromptu laughter or the wink of the eye

(well, the wink is exaggerated though...) Pixel peeping compared to 5d2 is entirely a different story, i'll not even go into that....
All that said, I'm using the EP-2 as a casual shooter since i'm mostly shooting film these days whenever possible... got a ZI, a M7, a Hexar AF and a medium format Fuji GA645i.... (too many!!!). The ZI and M7 are m mount so what I'm also achieving with the EP-2 is sharing of good glasses! Its certainly much more cost effective than acquiring a M8, much less the M9! I'm a 50mm frame shooter, the only problem with m43..... 2 x focal length ;(
