Abstract
A finder switching apparatus in a two-focus camera in which a finder is switched in conjunction with switching of a lens of the camera between shorter and longer focuses. The finder switching apparatus has a spring mechanism which can amplify a displacement of a parallax correcting lens which is adapted to move in interlocking engagement with the lens barrel so that the mechanism for moving the parallax correcting lens can be small. Accordingly, the two-focus camera having the finder switching apparatus according to the present invention can be made compact, since the space required for storing the finder switching apparatus in the camera is small.
