An imaging apparatus includes a main body having an imaging element; a rectangular display disposed along one surface of the main body; and a hinge unit that movably connects the display to the main body. The hinge unit includes a support portion connected to the main body so as to be rotationally movable about a first axis by a pair of first hinges on the first axis extending along one of two sides of the display which are at right angles to each other. The display is supported by the support portion so as to be rotationally movable about a second axis by a pair of second hinges on the second axis extending along other of the two sides of the display which are at right angles to each other. One of the pair of first hinges is disposed between the pair of second hinges.

A camera device including a mover comprising a first magnet; a lens; a stator including a first coil; a first substrate; a second substrate movably disposed on the first substrate; an image sensor disposed on the second substrate; a second coil disposed on the first substrate; and a second magnet disposed on the second substrate and facing the second coil is provided. The second substrate includes a coupling part coupled to the image sensor, and an extension part extending outwardly from the coupling part so that at least a portion thereof overlaps with the first substrate in the optical axis direction, and the camera device further includes a ball disposed between the first substrate and the extension part of the second substrate.

An accessory is detachably attachable to an electronic apparatus including a display. The accessory includes a communication unit configured to communicate with the electronic apparatus and an operation unit. If an operation is performed on the operation unit after the communication unit transmits information indicating a type of the accessory to the electronic apparatus, the communication unit transmits, to the electronic apparatus, a request for causing the display to display a setting image related to the accessory.

An observation device according to the present invention includes an image display element displaying an image, and a finder optical system used for observing the image displayed on an image display surface of the image display element. The finder optical system includes a positive first lens, a negative second lens, and a biconvex positive third lens arranged in this order from the image display surface side to the observation side. A focal length of the second lens, a focal length of the finder optical system, a curvature radius of a lens surface of the second lens on the image display surface side, a curvature radius of a lens surface of the second lens on the observation side, a diagonal length of the image display surface, and a curvature radius of a lens surface of the third lens on the image display surface side are appropriately set.
