10. Autofocus

A short focal length and the poor light make the sharpness depth in this kind of equipment huge. All the possible errors in autofocus operation are less burdensome than in the case of fast lenses. Tokina, fortunately, does not make many errors. It sharpened incorrectly only 6% of the time in test conditions.

In spite of the fact that the Tokina does not have an ultrasonic speed, it is hard to complain about its speed of operation. Nor can anyone complain about it being loud.

We did not notice any special tendency as far as front or back focusing is concerned, although because of the sharpness depth size, it is easy to miss a slight front or back focus.
