The autofocus of the Olympus 1.8/8 is silent and super fast – so fast that in fact it was difficult to measure it in a reliable way. Anyway the time needed to run through the whole range and confirming the focus didn’t exceed 0.3 of a second.
The depth of field, provided by fisheye lenses is large; additionally the autofocus testing chart itself is significantly deformed by distortion. It might create huge problems when you want to assess whether you deal here with any front or back focus tendencies. Anyway during our outdoor sessions we didn’t experience any problems in that area.
