Well, since I have a K-mount EVIL now, it's time for measurbation!

Well, as usual for my recent mesurbation tests, I won't provide any further comments myself. Go inspect, measurbate, compare, observe yourself, provided that you have the bandwidth and time! ;-D

Look like GF1 photos are more saturated and sharper. Anyway, I'm a bit amused with the building in HK. Why do they build almost the same kind of apartments (design wise).

Yes, the "Nature" "Film Mode" of the GF1 is a bit saturated and more sharpened by default. But I do like its colour accuracy over the other modes which are worse.

As for the buildings you see in the pictures, they are mostly those constructed by the government (public estates or subsidised compartments) and you can also see some old shorter industrial buildings at the front nearer to the sea.
it seem like EVIL one doesn't have any DOF

Well, actually it has more DoF! :-)
FA*85 and FA43 are sharper than EF85

But actually I found the colour rendition difference is more important than the sharpness difference. The EF could look sharper stopped down, but the Pentaxes surely produce more favourable colours. It is even more noticeable when the lenses are used for portraits, for what the 85 should be.
Colours can be fixed in PP, details can not be recovered...

Or, in either ways and for both actually. Also, the EF lens images look sharper doesn't mean it resolves better, the lens just does more sharpening than the other, just believe it or not! :-)
85s are meant for portraits. At least used a stuffed animal for test shots.
