    Abstract: A lens barrel of the invention includes: an imaging optical system including a focus adjustment lens; a driver that drives the focus adjustment lens in a direction of an optical axis; a transceiver that transmits and receives a signal to and from a camera body; and a controller that controls the transceiver to repeatedly transmit a first image plane transfer coefficient which is determined in correspondence with a position of the focus adjustment lens included in the imaging optical system and a second image plane transfer coefficient which does not depend on the position of the focus adjustment lens to the camera body at a predetermined interval, and, when the controller repeatedly transmits the second image plane transfer coefficient to the camera body, the controller varies the second image plane transfer coefficient over time.

    Abstract: An imaging apparatus includes a second mount configured to bayonet-couple with a first mount. The second mount has multiple contact points disposed in a circumferential direction that are to be electrically connected to multiple contact faces on the first mount when coupled. The number of the contact points is an even number of four or larger. When viewing the imaging apparatus in a normal position from the second mount side, a line extending from a center axis of the second mount in the gravitational direction and an opposite direction is a first mount center line, and a line orthogonal thereto is a second mount center line. The contact pins include a first contact pin that overlaps the first mount center line, and second and third contact pins at both ends in the circumferential direction of the second mount, with generally the same distance to the second mount center line.

    Abstract: An image pickup apparatus includes a main mirror holder rotating between a mirror down position in an image pickup optical path and a mirror up position outside the image pickup optical path in accordance with drive of a mirror driving unit, which drives in accordance with rotation of a motor, a sub mirror holder being supported by the main mirror holder to abut against the main mirror holder positioned at the mirror up position, and a driving pin rotating in accordance with the drive of the mirror driving unit and rotating the main and sub mirror holders. The driving pin includes an abutting part that abuts against the mirror driving unit while the mirror driving unit drives. The abutting part is provided with a reduction structure to reduce a bound of the sub mirror holder when the main mirror holder reaches the mirror up position.

    Abstract: A mirror drive device capable of achieving high responsiveness and driving stability, and suppressing mirror bounce. The mirror drive device includes a mirror box. A main mirror holder has a main mirror rotating shaft rotatably supported by the mirror box, and rotatably holds a main mirror between a mirror-down position and a mirror-up position, A sub mirror holder has a sub mirror rotating shaft rotatably supported by the mirror box, and rotatably holds a sub mirror between a mirror-down position and a mirror-up position. The main mirror holder and the sub mirror holder are connected by at least one connecting member. A drive member is engaged with the connecting member, and is driven for rotation by a motor. The sub mirror holder is directly driven by the drive member, and the main mirror holder is driven by the drive member via the connecting member.
