Example

var options = {
  camera: navigator.mozCameras.getListOfCameras()[0]
};
 
function onSuccess(camera) {
  var zooms = camera.capabilities.zoomRatios;

  if (Array.isArray(zooms)) {
    zooms.forEach(function (value) {
      console.log(value)
    });
  }
};

navigator.mozCameras.getCamera(options, onSuccess)

Specification
