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?

Yes i know for sure that there is a big difference between a camera which use a a top prime lens and a top zoom lens if you take a picture!

I think depending of the type of lens almost 500 -600 lines and it depence also if there is a FF SENSOR OR A C-SENSOR OR A MFT SENSOR INVOLVED.

And that is a lot!
