Lee Adaptor Rings screw onto your lens to accommodate the filter holder or lens shade. Once the ring is in place the holder clips into place using a smooth, quick release spring loaded mechanism. Wide-angle adaptor rings are designed so that the filter is placed as close as possible to the front element of the camera lens, and should be used when vignetting is encountered with a standard adaptor ring. Sturdily constructed with an aluminium screw thread, this is a wide angle adaptor ring for lenses with a 55mm filter thread.
