The popular SmallRig 4439 and 4438 bottom mount plates for the Sony a7C II and a7CR cameras have enough room for an Apple AirTag in the battery door cavity. This minimalistic AirTag holder slides into this area to securely and discreetly attach the tracker to your camera. It is designed to stay in place via press-fit, so it snugly grips the walls of the baseplate. To assist in removal, a gap for a finger is provided behind the hinge arm that is accessible when it is open. There is a chamfer along the arm to make opening easier.
