If you have a Panasonic Lumix DMC-LX5 and you want to use a wider angle lens, or a neutral density filter (for slower shutter speeds for special effects), or maybe a circular polarizing filter (to remove glare), you'll need this DMW-LA6 Conversion Lens Adapter from Panasonic. This adapter has a 52mm thread and a finish that matches the camera. It's made from high-quality aluminum.
