(1) “this camera is provided with 2 kinds of finder systems: two eyepieces arranged side by side in the eye cup. The left-hand side eyepiece is a single-lens reflex viewfinder through which you can see a fully open shooting frame. The right-hand is a range finder through which you can see only a central part of the subject. When the subject is out of focus, the image looks double. Turn the focusing ring until the double image becomes one.”
