More modern designs have rangefinders coupled to the focusing mechanism, so that the lens is focused correctly when the rangefinder images fuse compare with the focusing screen in non- autofocus SLRs.Īlmost all digital cameras, and most later film cameras, measure distance using electroacoustic or electronic means and focus automatically ( autofocus) however, it is not customary to speak of this functionality as a rangefinder.
