ABSTRACT:
A finder device is disclosed wherein light from an objective optical system passes through a finder frame to an eyepiece. The finder frame includes two spaced-apart support pins, a screen format switchable mask mounted to the support pins so as to enable a particular screen format to be selected from among at least two alternative screen formats, and a mask pressure plate which is mounted to the support pins so as to retain the screen format switchable mask on said support pins. Markings, useful for taking photographs, are provided on the transparent region of the screen format switchable mask or on the mask pressure plate. In this manner, markings useful for taking photographs, which be viewed with an object to be photographed when looking through the eyepiece of the finder, can be manufactured with less expense and fewer defects than previously.
