It is desirable for the electroluminescent display to be formed integrally with the focusing screen.
It is desirable for the electroluminescent display to display the object image captured by the image pickup device and various information, when the main mirror is retracted from the optical path of the photographing lens, and for theelectroluminescent display to only display the various information when the main mirror lies on the optical path of the photographing lens.
It is desirable for the single-lens-reflex digital camera to include a light shield screen which selectively covers and uncovers a surface of the focusing screen which is adjacent to the main mirror.
It is desirable for the single-lens-reflex digital camera to include a mirror drive mechanism which drives the main mirror, and a light shield screen drive mechanism which retracts the light shield screen from a position thereof which covers thesurface of the focusing screen. The mirror drive mechanism and the light shield screen drive mechanism are integrated with each other.
It is desirable for the main mirror to be retracted from the optical path of the photographing lens in the case where the photographing lens has an image stabilizing capability.
It is desirable for the single-lens-reflex digital camera to be configured to allow the object image displayed by the electroluminescent display and the optical image formed on the focusing screen to be selectively viewed through the viewfinder.
It is desirable for the electroluminescent display to be positioned on one side of the focusing screen from the main mirror.
It is desirable for the single-lens-reflex digital camera to include a light shield screen which is selectively inserted into and retracted from a space between the focusing screen and the main mirror when the main mirror is in a retractedposition in which the main mirror is positioned out of the optical path of the photographing lens.
