It seems a shame that arguably THE most impressive lens ever produced by Panasonic for the m4/3 lens mount is the 20mm f1.7. Not only is it a stellar performer but it was the first fast normal lens which effectively made the m4/3 system more attractive to photographers. Your list of "BEST" for GH3 and OM-D features quite a few poor lenses but strangely not the Pana 20mm f1.7. Why is this exactly? Go ahead and rate version II, but your readers in years to come would I'm sure be interested in seeing the first version in you archive.
One other point is that the lenses on the GH3 seem to have mostly the same rating as the GH2. Very interesting.
