1. Phase-detection autofocus (even using still targets and center-point only) wasn’t nearly as accurate as contrast detection

In most cases (especially with the latest M43 cameras) the autofocus is as good as you can get. IMHO, M43 does a noticably better job than the other mirrorless formats I've tried. I love the the touch shutter that will AF on the exact spot you pick and snap the picture in an instant.

I agree but the asking is.... what kind of resolution you get with e.g the 35-100/2.8 lens on a gh3 in in resolutionlines in comparison with e.g. an other combination?

And that must be clarified by testers and reviewers?

So i need a figure.

Why do you think resolution changes because of the way you focus?  Clearly it may if a subject is out of focus, but since CDAF and manual focusing are very accurate, that should not matter.  Other factors such as movement, in-lens IS, shutter shock, etc. can matter.

Are you asking how much being slightly out of focus affects resolution?
