I'm going to give this a bump to ask again if anybody has any photos taken with the WCON-P01 they would like to post. I am interested in seeing what folks are doing with this converter.
You could also search instead of waiting for responses. Plenty of material can be found with this simple search:

The converter is OK. It was one of the reasons why I chose Olympus vs Panasonic when I bought m4/3 camera in 2011. I switched from Ricoh compact camera with zoom starting from 24mm. I had to have 24mm or wider but didn't want to pay $500+ for native UWA. Olympus had this converter in 2011, that was the reason #4 or 5 in order of importance to choose Olympus with kit zoom.
It doesn't significantly degrade kit zoom IQ which stays pretty good, corners may suffer, but just a little. I was happy with it and I took some photos that wouldn't be possible with 28mm equivalent lens. I wrote about it in 2011 and I have some photos in my gallery.

Horseshoe bend in Arizona requires lens a bit wider than 24mm equivalent.

But then there is a distortion

At that time I was clueless, I didn't correct distortion and I sometimes shot kit zoom wide open with converter. Stopping down to F5.6 would have made corners better. Barrel distortion can be fixed (it would become rather 11.5-12mm lens then). And, as opposed to newer Panasonic WA converter WCON-P01 can be used at longer focal lengths if you don't have time to unmount it.
In the end, in half a year I bought Olympus 9-18mm and sold converter. The reason was - 9-18mm (although not stellar lens) still has better sharpness across the frame at 11-12mm even if you stop down kit zoom with converter. Converter gives more aberrations and it's more prone to flare (no hood possible). 9-18 is more compact than kit + converter, it doesn't have that distortion and 9mm is much wider than 11mm.
But I can understand someone choosing WCON-P01 converter - if one makes LR profile to correct barrel distortion, careful about flare and CA, uses it at stopped down, this can be a decent UWA lens.
