Electronic viewfinder Electronic viewfinders are used in digital still cameras and in video cameras.

- A rangefinder works by having 2 windows that view the subject a slight distance apart. One creates the direct view image in your viewfinder, the other creates a center spot (a small area superimposed on the main image) that's used to focus-this spot is usually somewhat illuminated.ost varieties of rangefinder show two images of the same subject, one of which moves when a calibrated wheel is turned; when the two images coincide and fuse into one, the distance can be read off the wheel.
