<p>This type allows control over manual and automatic focus settings, including information about any parts of the camera frame that are selected for autofocusing.</p>
<p>It should not be constructed separately, instead the <code>focus</code> property of a <a href="qml-multimedia.html#camera">Camera</a> should be used.</p>
