10. Autofocus

The autofocus of the tested lens, joined with the Olympus OM-D E-M5 Mark II, is silent and very fast. Focusing is so short that it's actually difficult to measure. Running through the whole distance range and confirming the focus takes less than 0.2 of a second, a sensational result that doesn't depend either on the direction of work or the focal length applied. A round of applause!

We also didn't have any problems with the accuracy of the mechanism – both in studio and outside we enjoyed 100% of accuracy as the lens practically didn't miss at all.

Photos below show that the autofocus didn't have any distinct front or back focus tendencies either. An image we got at 18 mm does feature a slight DOF shift toward greater distances but the proper object remains sharp all the same. Mind you that photo was taken at the most difficult combination, meaning the maximum relative aperture and the minimum focusing distance. Perhaps a part of that shift is connected to a specific field curvature which, in such complex constructions, is almost never an ordinary sphere segment.
