    摘要: A finder block comprises a condenser lens, an image-forming lens with its optical axis intersecting the optical axis of the condenser lens approximately at right angles, a first reflecting plane for reflecting incident light on the condenser lens toward the image-forming lens, a second reflecting plane formed on the rear face of the first reflecting plane, a second incidence window for the second reflecting plane, and a second eyepiece window for viewing an image reflected from the second reflecting plane. A support member, shiftably attached to the camera main body, can support the finder block on the camera at the objective side or eyepiece side of the camera finder or at a position other than these positions as desired.
