To all intends and purposes a fisheye lens can make do without an autofocus. Working on full frame at 8 mm, even wide open, you can enjoy sharp images in the range from 0.9 of a meter to infinity when you set the distance scale at 1.8 metres. On stopping down the situation becomes even better.

In some settings, however, the autofocus might come in handy and then we have an ultrasonic USM drive at our disposal. Its work is beyond reproach – it is silent, quick (running through the whole scale takes less than 0.5 of a second) and accurate. What’s more, we didn’t experience any front or back focus difficulties on any body available in our editorial office.
