Abstract: A finder includes, in order from an object side to an eye point side, an objective optical system that forms an intermediate image, and an ocular optical system that is provided for observation of the intermediate image. The intermediate image is positioned on the optical path between the objective optical system and the ocular optical system. The finder includes a plurality of reflecting surfaces for forming an erect image, and each of the objective optical system and the ocular optical system has at least one of the plurality of reflecting surfaces. The finder satisfies a conditional expression: 2<fo/fe<8 regarding a focal length fo of the objective optical system and a focal length fe of the ocular optical system.

Abstract: The imaging lens includes, successively in order from a position closest to an object side: a first lens group that remains stationary with respect to an image plane during focusing; and a focus lens group that moves along an optical axis during focusing. Assuming that a maximum image height is Ymax, and a focal length of the imaging lens is f, and a sum of a back focal length in terms of an air-equivalent distance and a distance on the optical axis from a lens surface closest to the object side to a lens surface closest to the image side is TL, the imaging lens satisfies Conditional Expressions (1) and (2). 0.1<Ymax/f<0.26??(1): 0.4<TL/f<1.

Abstract: Provided is an observation apparatus capable of adjusting visibility of an image and of an optical image of a subject in consideration of an intensity of ambient light in a case where the image is displayed by being superimposed on the optical image. The observation apparatus (30) includes an optical system (32), a display mechanism (34) that displays an image based on a signal generated by an imaging element (20), and a light shielding mechanism (36) of which a light shielding rate is variable, and the optical image has a first optical region (OP1) and a second optical region (OP2). The display mechanism (34) superimposes the image on the first optical region (OP1) to display both the image and the optical image in an observable manner by a user.
