I came across this interesting 3-part comparison: http://tysonrobichaudphotography.wo...ttle-for-my-affection-round-1-ibis-evfs-lcds/ (I don't know if that link is "clickable" - if not copy and paste to your Internet browser.) The author concludes he favors the Panasonic, but his comparison is detailed and even-handed - a good read! I'm getting ready to update my gear and both of these cameras appeal strongly to me. As a jpeg shooter who has no interest in video (I really don't see the point of spending minutes or hours editing something captured in a few milliseconds and I don't make movies), I lean strongly to the Olympus offering. I now use an Olympus e-520 and a Panasonic G1. I love both and like the union of features from them both of these new cameras offer. I do a lot of shooting with legacy lenses, mostly of static objects or a cat in motion - IBIS and an electronic viewfinder have both proved really advantageous to me. I'm still torn and confused!
