title: Camera AutoFocus not turning off
body: <p>I'm using a Moto X and I want to turn off AF to then set the focus distance manually.</p>
  
  <p>To this end I'm setting </p>
  
  <pre><code>CaptureRequest.ControlMode to auto
  CaptureRequest.ControlAfMode to off
  </code></pre>
  
  <p>and then setting focus distance using</p>
  
  <pre><code>builder.set(captureRequest.lensFocusDistance, 1/focusDistance)
  </code></pre>
  
  <p>I'm also using as a cameraTemplate preview.</p>
  
  <p>Using these settings am I right in thinking that the preview should be out of focus and not autofocus?</p>
  
  <p>However the preview autofocuses</p>
