On the model 600SE, a metal mask (with a pattern of holes) blocks the light from one of the
framing images. Moving the viewfinder selector switch moves this metal mask to reveal one
framing image on the film, and blocks the other framing image.
As the camera is focused from infinity to close up, the rangefinder coupling pin moves the framing-
mask assembly. This causes the framing line image to move down, as shown in Figure 2-2. This
compensates for the change of viewing angle, between the camera lens and the viewfinder lens.
At the same time the rangefinder coupling pin pivots the movable mirror. This moves the movable
image from left to right. When the movable image coincides with the fixed image in the focusing
circle, the camera is in focus.
Viewing and Focusing with the 75MM Lens and Accessory Viewfinder
An accessory wide angle viewfinder is supplied with the 75mm wide angle lens. Figure 2-5
shows the accessory viewfinder ready to be attached to the cold accessory shoe on top of the
camera.
Note: It is possible to attach an accessory viewfinder incorrectly. Avoid attaching the viewfinder
partially unlocked or backwards. Do not attach the accessory viewfinder to the hand grip
flash shoe.

screw interfering with full
