View finder for camera with different selectable finder field frames |
摘要 |
A camera view finder having at least two types of finder field frames such as a full-size field frame and a panoramic field frame, only one of which can be observed in accordance with a selected photography mode. In a first embodiment of an Albada-type inverted Galilean view finder, one of two types of finder field frames is light-shielded by a blocking member. In a second embodiment, a finder field frame is formed on each of at least two adjacent surfaces of a transparent cubic body which is rotated to position a selected finder field frame in the finder optical path. For a Keplerian view finder, a finder field frame is formed on each side of a transparent plate which is moved along the finder optical path to position a selected one finder field frame in the real image plane.
