XF-1 first observation vs OLY XZ-1

I just got xf-1 yesterday as potential replacement to OLY xz-1. I compared it in whatever light conditions I can get in this gloomy weather.

It can be called a little upgrade from xz-1 but not by a long shot. It is faster and seems to have better high ISO (but not that much). The xz-1 lens is still better (especially edges). In low ISO and good light - surprise surprise, I wasn't sure the xf-1 gives much advantage in overal IQ (It has more pixels for details, but the xz-1 seems smoother and cleaner for indoor shots).

I expect the xf-1 to have better details in grass and foliage in JPG as the olympus JPG like to turn greens into mush.

It is more pocketable due to folding lens.

So if anybody else wonders, I'd still suggest to keep the xz-1 for a year as the differences are minimal.
