Made of black anodized aluminium. The unique lens adapter provides a 52mm filter mount for adding effects filters to the Panasonic DMC-LX5 Digital Camera, improving picture quality by adding a filter(UV, CPL etc.) and protecting your camera lens from scratching. The adapter also allows user to add other lens accessories(as tele/close-up/wide-angle lenses) to the camera. Vignetting might be caused at the widest zoom.
