Canon EOS 1Ds Mark III White Paper page 15

As with the EOS-1Ds Mark II, the superimposition display consists of the lead-in compo-
nent, integrating the dichroic prisms (SI prism 1 and 2) with the pentaprism and the illu-
mination (SI-LED), liquid-crystal (SI-LCD), and the eyepiece lens. Compared with the
EOS-1D Mark III's dichroic mirror system, the dichroic prism system can have a more
compact light path in the lead-in component. This contributes to a higher viewfinder
magnification.

The exceptional legibility of the viewfinder means it is now a practical option to include
a great quantity of information in the finder display.
