The autofocus was tested on such bodies as the Panasonic GH4 and the Olympus E-PL1. When the lens was attached to the former its autofocus was noiseless and very quick. Running through the whole distance scale and finding the focus took about 0.4 of a second which is an impressive result. When attached to the Olympus camera the autofocus of the tested lens was a bit slower and focusing might take about 0.6-0.7 of a second.

We don’t have the smallest reservations concerning the accuracy of the focusing mechanism – in studio conditions it didn’t miss one single time. What’s more, in the case of both bodies we didn’t notice any front or back focus tendencies either.
