      * <p>By using this control, the application gains a simpler way to control zoom, which can
      * be a combination of optical and digital zoom. For example, a multi-camera system may
      * contain more than one lens with different focal lengths, and the user can use optical
-     * zoom by switching between lenses. Using zoomRatio has benefits in the scenarios below:
-     * <em> Zooming in from a wide-angle lens to a telephoto lens: A floating-point ratio provides
-     *   better precision compared to an integer value of ACAMERA_SCALER_CROP_REGION.
-     * </em> Zooming out from a wide lens to an ultrawide lens: zoomRatio supports zoom-out whereas
-     *   ACAMERA_SCALER_CROP_REGION doesn't.</p>
