２）Superimposition display
The superimposition display optics consists
of the SI-LED, SI lens, and SI prism. They are in
front of the pentaprism. The SI-LED's light beam
goes through the pentaprism and it is projected
onto the reflective panel that has the AF points'
reflective areas. The light path is shown in Fig.
021.
