PROBLEM TO BE SOLVED: To provide a camera constituted in such a manner that a fixed visual field frame and a moving visual field frame are positioned with high accuracy to each other when the moving visual field frame is slidingly moved near to the fixed visual field frame. SOLUTION: This camera has the fixed visual field frame which has a first aperture forming the visual field of a finder and the moving visual field frame which has a second aperture shorter in at least either of the long side or short side than the first aperture and slides in order to insert and remove the second aperture relative to the first aperture. When a visual field different from the visual field of the first aperture is formed by sliding the moving visual field frame and inserting the second aperture to the position facing the first aperture, a second guide part disposed on the front end side of the moving visual field frame in the insertion direction is fitted to a first guide part disposed on the deep side of the fixed visual field frame in the same direction.
