A lens apparatus is mountable to a camera body. The camera body has multiple electric contacts. Of these multiple electric contacts, when mounting the lens apparatus to the camera body, electric contacts used for second communication or third communication come into contact with an electric contact provided to the lens apparatus before electric contacts used for first communication, when mounting the lens apparatus to the camera body.

In some embodiments, devices and methods are provided herein useful to grip, hold, and/or manipulate the objects. In some embodiments, a gripping device may include a coupler configured to physically couple to a device moving member, a movable member having an object-facing surface, a actuator for actuating the movable member between a retracted position and an extended position, and a plurality of pins fixed on the object-facing surface of first movable member, each of the plurality of pins comprising an end configured to penetrate a surface of a gripped object when the movable member is in the extended position.
