Olympus M.Zuiko Digital 40-150 mm f/2.8 ED PRO
10. Autofocus
We don’t have any reservations concerning the accuracy of the focusing mechanism. In studio conditions the lens joined with any of two bodies, used in our test, hit the aim in 100% of cases.
When it comes to the front or back focus tendencies we managed to notice just one slight problem: after attaching the lens to the teleconverter the depth of field was shifted a bit toward the longer distances.
