An accessory is attachable to, detachable from, and communicable with an electronic apparatus. The accessory includes an accessory processing unit configured to make a communication request to the electronic apparatus and to transmit information about a factor of the communication request. The accessory processing unit notifies the electronic apparatus by a first communication method of information corresponding to a used communication method for communicating the information about the factor, among the first communication method and a second communication method different from the first communication method.

An electronic apparatus attachable to an accessory includes a power supply unit, and a control unit for controlling the power supply unit. The electronic apparatus can transition from a normal operating state to a power-saving state that includes a first power-saving state in which a power supply switch of the electronic apparatus is turned off, and a second power-saving state in which a non-operating state continues for a predetermined time. The control unit receives first information indicating whether or not the power supply from the electronic apparatus to the accessory is requested in the first power-saving state, and second information indicating whether or not the power supply from the electronic apparatus to the accessory is requested in the second power-saving state. The control unit causes the power supply unit to supply the power in the power-saving state where the power supply is requested.

A support apparatus for an electronic device includes a support portion that movably supports the electronic device between a first position where an object stored in the electronic device is incapable of being taken out, and a second position where the stored object is capable of being taken out. The electronic device is attachable to the support portion, and the electronic device is moved between the first position and the second position by movement of the support portion. In addition, the support apparatus o includes a base portion to which the support portion is movably attached, and the movement of the support portion causes the electronic device to move between the first position and the second position.

An electronic apparatus to which an accessory is detachably attached, the electronic apparatus includes a receiving unit and a processing unit. In a case where a first accessory is attached to the electronic apparatus via a second accessory, the receiving unit receives, from the first accessory, first information indicating whether or not an operation of the first accessory attached to the electronic apparatus via the second accessory is to be permitted, and the processing unit makes different control over the operation of the first accessory in accordance with the first information.

An electronic apparatus which prevents occurrence of a malfunction even when multiple accessories are attached to the electronic apparatus directly or via an accessory connector. The electronic apparatus includes an attachment part to which an accessory connector is attachable or to which multiple accessories are attachable. On the accessory connector, multiple accessories are attachable. When multiple accessories have been attached to the attachment part or on the accessory connector attached to the attachment part, accessory information is obtained via the attachment part from each of the attached accessories. In a case where overlapping accessories with overlapping functions are found based on the accessory information, the overlapping function of at least one of the overlapping accessories is restricted.

There is provided a mounting assembly comprising: a base against which the photographic device is placeable in use, the base comprising an engagement structure arranged in use to provide engagement of the base with the support; a connector engaged with the base in use and arranged in use to removably connect to the photographic device; and an extension plate securable to the base in a plurality of positions and removably securable to a side element, an amount of overlap of the extension plate and base being determined by the position in which the extension plate is secured to the base, the position of the side element relative to the base thereby being movable.

A connecting device of an accessory by which improvement in mechanical strength is compatible with arrangements of many connection terminals. The connecting device is detachably attachable to an accessory shoe device of an electronic apparatus. An engagement member is attachable to the accessory shoe device by sliding in a first direction. A holding member is fixed to the engagement member by fastening members. A connecting plug has connection terminals and is arranged at a front part in the first direction of the holding member. The fastening members are arranged at positions that are spaced apart from each other in a second direction that perpendicularly intersects with the first direction. A width of the holding member is shorter than a width of the engagement member in the second direction, and the connection terminals are arranged in an area between the positions of the fastening members.

A camera matte box electrically controls an adjustable lens filter. The camera matte box includes a body, at least one adjustable flap, a filter holder, a changeable lens adapter, and an electrical filter control module. The electrical filter control module adjusts a position of the adjustable filter according to a command received using a communication interface. The filter holder removably holds the adjustable filter and a non-adjustable filter in the body.

The disclosure is generally related to an apparatus is configured to mount an optical device to a phone and align the optical device with the camera of the phone. The apparatus includes a first body having an arcuate shape, the first body having an inner side, an outer side, a top, a bottom, a first end, and a second end. The bottom includes a first recess and a second recess positioned within the first recess. The apparatus includes a second body connected to the inner side of the first body. The second body is movable inwards and outwards with respect to the inner side of the first body. The apparatus includes a strap connected to the first body to connect an optical device. The apparatus includes a magnet positioned within the second recess. The magnet connects the apparatus to a ferrous element connected to the back of phone.

A lighting device with an annular rectangular light that connects to the camera assembly by mechanical linkages. The annular rectangular light can connect to different components of a camera. The annular rectangular light can connect to a matte box or rods of the camera in some embodiments. The mechanical linkages allow positioning of the annular rectangular light such that it surrounds the front of a lens of the camera but does not obstruct a field of view of the lens.
