10. Autofocus

The autofocus of the Batis joined with the Sony A7R II is noiseless. We also don't have any reservations concerning its speed, especially that the lens is able to focus already from a distance of 0.24 of a meter, reaching in this area a better result than its rivals. Running through the whole range from the minimum focus to infinity, takes just about 0.4-0.5 of a second and it is a good value. The other way round the lens is a bit slower so it takes 0.5-0.6 of a second; you can also notice some focus play near the proper position.

Of course you are able to speed up the performance a bit by limiting the focus to a range from 0.4 of a meter to infinity. Then the lens is able to set the focus even as fast as 0.3 of a second.

The accuracy of the autofocus can be described in superlatives only. The lens didn't cause us any problems, no matter whether we used it in the studio or outside.
