A camera lens holder comprising a cylindrical body formed or attached to a perpendicularly aligned planar base. The cylindrical body has sidewalls and coaxially aligned cylindrical cavity with a top opening with a chamfered inside edge. The diameter of the cylindrical cavity and the length of the sidewalls are sufficient in diameter and length to receive and hold the bayonet-style end connector on a camera lens. Formed on the inside surface of the cylindrical body are lugs configured to engage the lugs formed on the bayonet-style end on the lens. Formed on the outside surface of the cylindrical body are two or more projecting wings. Attached to the bottom surface of the planar body is a hook connector pad configured to connect to the inside surface of a camera bag made of cotton, nylon or felt material. The chamfered inside edge of the cylindrical body is configured to allow the user to easily insert the bayonet-style end connector on the lens without precisely aligning the lens over the top opening.

To make it possible to simply and easily attach/detach an attaching target to/from an attached target. A coupler includes: a base to be fixed to an attached target; and an attachment body that is fixed to the attaching target and to be detachably joined to the base, in which: the base includes a joint surface to be joined to the attachment body, a magnet configured to magnetically attach the attachment body to the joint surface, and an engaging part configured to engage with the attachment body; and the attachment body includes a joint surface to be joined to the base, a magnet configured to magnetically attach the magnet of the base to the joint surface, and an engaged part configured to disengageably engage with the engaging part of the base and restrict separation from the base.

A lens and/or a view screen of an electronic device having at least one case can be cleaned by wiping the view screen with a cleaning component wherein the cleaning component is configured to selectively couple to the at least one case or some other substrate using a magnetic attractive force. The cleaning devices may have secondary applications such as securing fly fishing lures, activating or deactivating a device having a magnetic switch, or preventing sunglasses from sinking. They may also be manufactured without a cleaning component for use with the secondary applications.

A mounting apparatus for a light socket assembly comprises an extension body connectable with the light socket assembly. The extension body defines a first arcuate surface extending from the extension body. A clamping assembly has a second arcuate surface extending from the clamping assembly. The first arcuate surface and the second arcuate surface are each contoured to conform with and to pivotally contact each other, at least in part, with sufficient friction that the extension body and the clamping assembly are selectively positionable and pivotally movable relative to each other in response to intentional repositioning of the extension body and the clamping assembly relative to each other. The apparatus thus provides for mounting of a light socket assembly on a wide variety of environmental items, such as, for example, trees, eavestroughs and the like, and is particularly useful for mounting a string of wired festive lights, such as Christmas lights.

A case and a system for wirelessly pairing, storing and charging an adjunct camera to a handheld electronic device, such as a smartphone. A software application on the device controls the adjunct camera. In one embodiment, the case provides a telescopic rod to elevate the adjunct camera. In another embodiment, the case provides a cable on a retractor reel operative for connecting the adjunct camera to the case. The adjunct camera is selectively detachable from the case and attachable to a user or other object for hands-free operation once the software app is engaged. The case, the adjunct camera, the electronic device and the app comprise a system for capturing, streaming and saving video and photos by expanding the reach of the native camera function of the electronic device.

A portable case adapted for the integral mounting of optical equipment having a split hinge tubular enclosure defining an equipment mounting interior cavity. An adjustable mounting rail system adjustably supports both the optical lens array and optical camera providing a self-contained pre-mounted enabled optical recording platform.
