FF: Fixed focus, the focus point of the lens is fixed

AF: Auto focus, adjust the focal length as the distance between the observed object and the camera changes

TOF camera: time of fly, a camera that could know the distance between a sensor and an object even calculate and produce results of the size of an object using the method of time of fly.

EFL: Effective Focal Length, definition: refers to the distance from the center of the lens to the focal point
