10. Autofocus

The Zeiss 24-70 mm was equipped with an ultrasonic SSM motor and you can hear and see it instantly. The work of the autofocus is practically noiseless and as fast as a flash, running through the whole scale in less than 0.5 of a second. We don’t have any reservations when it comes to the accuracy of the tested focusing mechanisms because the number of misses in studio conditions reached just 2%. Additionally we didn’t notice any front or back-focus tendencies.

If you want to pick holes at a push, though, the best place to do it is the performance against bright light. The autofocus often got mad there and partially the body is to be blamed for it. The same lens is guilty partially too because it seems the same body with the Sony 1.4/50 and with the Sigma 1.4/30 attached fared somehow better.
