PROBLEM TO BE SOLVED: To prevent the deterioration of image quality on an imaging surface of a finder by effectively suppressing the infiltration of dust etc., to the imaging surface in the finder or near the same for the purpose of checking the imaging visual field of an imaging lens system. SOLUTION: In the finder system, a finder frame 14 including the finder optical system including a plurality of lens components slidably supports an arcuate curved cam plate 16. The imaging surface and a lens portion near the same are nearly hermetically closed in a unit assembly stage by the arcuate curved cam plate 16 formed to abut on the outer peripheral part of the lens barrel LB of the imaging lens system and the finder frame 14.
