A camera body according to the present disclosure is a camera body to which a lens barrel including an optical system is detachable and reattachable, the optical system being configured to include a plurality of lenses. The camera body includes: a controller which controls the camera body; an image sensor which obtains an optical image formed by the optical system; and an image sensor driver which drives the image sensor in an optical axis direction of the optical system. The controller detects optical feature amounts of a plurality of frames in a state where the image sensor is at an identical position in the optical axis direction, detects a frame in which a change amount of an optical feature amount calculated from a plurality of the detected optical feature amounts has exceeded a predetermined threshold, and drives the image sensor driver to move the image sensor from the identical position to a reference position provided in a movable range when there is a plurality of the frames in which the change amount has exceeded the predetermined threshold.

A lens barrel: an optical system; a focusing manipulation unit capable of changing a focal position of the optical system in a normal photographing area and in a macro photographing area where the focal position can be changed for an object located at a position shorter than a shortest distance position of the normal photographing area; a photographing mode switching unit for switching between a normal photographing mode and a macro photographing mode; and an index ring having a normal scale and a macro scale, the normal scale indicating an object distance in the normal photographing mode, and the macro scale indicating the object distance in the macro photographing mode. Then, the photographing mode switching unit switches a display position of the index ring between the normal scale and the macro scale, and the focusing manipulation unit changes the focal position displayed on the index ring by rotation manipulation.

Lens barrel and imaging apparatus

A lens barrel in the present disclosure includes: a lens frame; a movable lens held in the lens frame; a guide member that moves the lens frame in a first direction; a driver including a drive coil and a magnet that move the lens frame with electric power being supplied to the driver; a drive circuit that drives the driver; and a switching circuit that short-circuits ends of the drive coil when the drive circuit is in a non-energized state.

Lens barrel and imaging device equipped with the lens barrel

A camera body, to which a lens barrel having an optical system can be attached, includes a controller that controls the camera body, an image sensor that captures an object image, and an image sensor actuator that drives the image sensor along an optical axis. The controller determines a change in an optical state of the object image captured by the image sensor and, in response to the determination, drives the image sensor actuator to move the image sensor to a predetermined reference position located within a movable range of the image sensor.

An autofocus device includes: an imaging element; an imaging element driver; an imaging element driving controller; a detector; a focus determiner; and a speed parameter calculator. The focus determiner detects a focus position based on a contrast value. The speed parameter calculator calculates a speed parameter used to set a driving speed of the imaging element driver based on the contrast value. The imaging element driving controller performs first and second driving controls for detecting the focus position based on the speed parameter in an autofocus operation. Also, the imaging element driving controller sets, during the first driving control, a driving speed of the imaging element driver for the second driving control.
