Sigma 150/2,8 w MMF-3 on E-M5: having trouble

Good proposal. I have thought about that, but it doesn´t lock on any subject, not even when aimed in "90 degrees angle" (straight on) towards a flat surface like a newpaper spread, a subject which would not depend so much on exactly where in the "AF square" the camera happens to want to lock. But I will try and se what possibly happens when minimizing the AF-square.

Thanks anyway!
