A lens barrel includes: a first lens; a first tube that holds the first lens and moves along an optical axis; a focusing lens; an actuator that drives the focusing lens; and a second tube that holds the focusing lens and the actuator and moves along the optical axis.

Lens barrel and image capturing device

A calculation device calculating an amount of movement in an optical axis direction of a focusing lens which adjusts a focal position of an imaging optical system includes: a first input unit to which first information about a deviation between an imaging surface which captures an image by the imaging optical system and the focal position is repeatedly input; a second input unit to which second information about a shake of the imaging optical system in the optical axis direction is repeatedly input at intervals shorter than those of the first information; and a calculation unit which calculates the amount of movement on the basis of at least one of the first information and the second information, wherein the calculation unit calculates the amount of movement on the basis of the second information between an input of the first information and an input of the next first information.

Calculation device, interchangeable lens, camera body, and imaging device

A lens barrel and camera moves a lens in the optical axis direction at a high speed. This lens barrel is provided with: a first electromagnetic drive unit; a first lens holding frame, which holds a first lens, and moves the first lens in the optical axis direction by means of the first electromagnetic drive unit; a second electromagnetic drive unit; and a second lens holding frame, which holds a second lens, and moves the second lens in the optical axis direction by means of the second electromagnetic drive unit. The first lens holding frame is disposed on the inner circumference side of the second lens holding frame.
