10. Autofocus

As we wrote earlier we are surprised Canon didn’t decide to equip its lens with an USM motor dooming it to lag behind the rivals. However we must honestly say that the focusing mechanism is not noisy – you can hear only a low whirr. When it comes to its speed it can be assessed as medium at most. Running through the whole distance scale takes about 1 second.

The autofocus accuracy is also beyond reproach. In studio conditions the lens missed in only 2% of all cases. Additionally, at longer focal lengths, it didn’t have any tendency of getting lost and running through the whole scale again.

The lens didn’t require the usage of autofocus microcalibration, available in the EOS’s 50D menu, because it didn’t show any front or back focus tendencies.
