10. Autofocus

The autofocus of the tested lens was silent and very quick, no matter whether you attached it to the E-M5 of the E-PL1. Running through the whole distance scale and confirming the focus didn’t take more than 0.4 of a second, a very good result.

We didn’t notice any problems with the accuracy of the mechanism either. Both in our studio and outdoor the lens performed as it should, setting the focus in properly.

Photos below prove that, in the case of both bodies used in our test, the lens had a slight front focus tendency. Still you should mention the fact that effect was noticeable only at the minimum focusing distance and its level was so slight that it was difficult to say if it was a real autofocus effect or the influence of the curvature of the field and astigmatism (we mentioned these problems in the resolution chapter). In practice, we didn’t see any real problems while taking photos at typical working distances and close to infinity.
