When it comes to the newest Micro 4/3 bodies the focusing is fast and silent. Running through the whole distance scale, finding the focus and confirming it takes no longer than 0.3 of a second - a sensational result.

It would be difficult to have any reservations concerning the accuracy of the mechanism either – in studio conditions the lens didn’t miss one single time. When it comes to front or back focus tendencies we noticed such an effect only for the E-M10. Near the minimum focusing distance (where you can make the depth of field shallower) the focus range seemed to be shifted a bit before the object; still that object remained within the focus range so it was difficult to qualify it as a real miss. With the increase of the distance the depth of field became larger and the problem disappeared completely.
