The grip extension includes an upward lip with a minor magnetic member disposed therein such that a surface of the minor magnet member is exposed and faces forward. The auxiliary frame is coupled to the primary lens frame from the bottom such that the grip extension extends under the bridge portion in the primary lens frame and the upward lip engages the bridge portion of the primary lens frame on the rear side of the bridge, said major and minor magnetic members magnetically coupling together, thereby further securing the auxiliary frame to the primary lens frame.
