"looking myself looking at me"the focusing is done by the lens+camera by sending an EM signal to the object found in front of them ... and collecting the reflected EM signal by the object ... delay time taken by the signal to go and back to the lens/camera determines the distance of the object from the lens/camera ... if i'm 5 meters away from the mirror, what is the "distance" between me and my camera? and if the speed of light is 3x10^8 m/s, how long does it take for the EM signal to go and back to the camera? .... am i holding the camera or not?
