| | wrotniak.net: It's all done with mirrors |
 | | Until the shutter is released, the mirror stays in the "down" position, redirecting the light towards the viewing screen, and creating the real (as opposed to aerial) image on it, to be viewed through a magnifying eyepiece. |
 | | In addition to the "main" mirror, three others are used to redirect the screen image to the eyepiece — exactly like in the E-300 (a solution referred to as a "straight-line reverser", one of the two most common types). |
 | | Here the main mirror goes up for electronic viewing (disabling the optical finder), the shutter opens, and the live preview uses the signal from the main imager, very much like in the E-10, including the double close/open shutter sequence described in the discussion of the that camera (except that this is a focal-plane shutter). |
