is recommended.
When using a zoom lens, zoom all the way in.

2 Frame a featureless white object in the viewfinder.
With the lens about ten centimeters (four inches) from a well-
lit, featureless white object, frame the object so that it fills the
viewfinder and then press the shutter-release button halfway.
In autofocus mode, focus will automatically be set to infinity;
in manual focus mode, set focus to infinity manually.
