The lens is equipped with an SWM ultrasonic autofocus motor so the work of the mechanism is silent. During focusing you hear just a slight swoosh of shifted elements. The speed is not record-breaking though. Running through the whole distance scale, no matter from what end, takes the lens almost one second.

When it comes to the accuracy of the mechanism – we have no reservations here. In the studio conditions the number of autofocus misses reached only 2.5%. In the case of the D3x we didn’t notice any pronounced front or back focus tendencies. Photos taken with the D200 showed a bit more sharp area before the target but we must admit those shots are taken at the most difficult combination of parameters, when we are close to the target and it is situated in the depth of field range. With bigger distances that small problem becomes simply negligible.
