Canon EF 70-200 mm f/4L IS USM

10. Autofocus

The lens is flawless in this category. Equipped with the USM motor the Canon 70-200 f/4L IS works perfectly, very fast and quiet. In testing conditions the lens missed in just 3% of cases. We would like to add that after attaching the converter the accuracy didn’t change but the autofocus becomes much slower.
