The focusing mechanism, although, in the case of Summilux, not ultrasonic, on the Olympus E-3 works silently – you hear only a delicate buzz. It is very quick, it runs through the focus scale in about half of a second but we must notice that it is a bit slower when traveling from infinity to the short end than backwards.

The accuracy of the autofocus is beyond reproach. In studio, the lens missed in 6% of all attempts, which is the good and average level borderline. We haven’t noticed any backfocus or frontfocus tendencies.
