With it's high price tag I was expecting much from this lens on my GH3 but the edge resolution is disappointing under 25mm where my 14-45 is better at a fraction of the price. I shoot mainly at F8 and would expect any wide open edge losses to be resolved when stopped down but doing this on the 12-35 does very little. I was about to buy a 35-100 as well but was stopped when I started to read reports and see tests showing a similar so-so edge performance so this may simply be the design compromise of these lenses. On the plus side it has fast AF, weather sealed, fast aperture, a good solid feel and not bad edge resolution at 35mm. Think I'll sell it unless it's simply a bad copy.

The 12-35 apparently has strong distortion at the wide end. The distortion will not be apparent to JPEG shooters and anyone using a converter that fully supports MFT (such as Lightroom) as distortion is auto-corrected. There is no way to disable distortion corrections in programs such as Lightroom (it occurs regardless of options selected).

These distortion corrections come at the expense of resolution, particularly in the edges and corners. Were I shooting another format I normally wouldn't correct for distortion unless I absolutely needed to for that particular shot for examples straight lines... Perhaps if you tried a RAW converter that didn't force these corrections you might have better results? I believe you can fully disable them in DXO though it doesn't support the 12-35 on some bodies (E-PL5, E-PM2) currently (support is due next month).

Of course you would have to shoot raw...
