The Canon EF 2/35 isn’t equipped with a USM motor, which can be noticed, or rather heard, from the very beginning. While adjusting the sharpness a loud and irritating high pitch buzzing can be heard. It is hard to say anything good about the lens’s accuracy. The lens missed as much as 16% of the time. In the pictures below you can see the MTF results of 5 testing table pictures taken at f/4.0 diaphragm, where the sharpness depth, at 35 mm, becomes quite big and can easily mask small autofocus mistakes. In this case, the mistakes were not small so the masking didn’t help and the results were as follows (in LW/PH in JPG format): 1946, 1610, 1312, 1778, 1353 and1944. As you can see the very good results mix with medium and weak ones and the differences are significant.

Fortunately, we cannot complain about the sharpness of speed adjusting. It might not be USM motor like work, but the results are very good. We didn’t observe any tendency between front or back focusing either.
