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 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.

Lens barrel and camera

An imaging apparatus includes: an imaging unit that repeatedly captures images of a subject to obtain image information; a recording unit that records timing information indicative of a given point in time during an imaging period of the image information; and a display unit that displays an image corresponding to the timing information, which is extracted from the image information, in response to an end of the imaging period.

Camera capable of taking movie

An optical device includes: a holding frame holding an optical system; a tubular member provided at an outer circumferential surface with a first concave groove and at an inner circumferential surface with a second concave groove, and holding the holding frame; and an eccentric pin penetrating through the first and second concave grooves, including one end attached to the holding frame, and eccentrically rotating against the first and second concave grooves in response to a force applied to the other end of the eccentric pin. A length, in a first direction intersecting a penetrating direction through which the eccentric pin penetrates, of the first concave groove is greater than a length, in a second direction intersecting the first direction and the penetrating direction, of the first concave groove.

Optical device, optical apparatus, and method of manufacturing the same

A blur correcting device comprises: a blur correction optical system that corrects an image blur by moving along a direction substantially perpendicular to an optical axis; a locking member that locks the blur correction optical system when an image blur correction is not executed; and a lock drive device having an elongated external shape with a length thereof set along a direction in which a tangential line of a circle having a center thereof at the optical axis extends on a plane substantially perpendicular to the optical axis, which generates a drive force to drive the locking member.
