Works, the camera will take but thicker

My Sony RX100 II has a Hama-hardcase in a low-cost standard size for Transport. Because they fit in exactly. The adapter makes the camera 3 mm thick. The hardcase can still close, but it spanned already clear. Otherwise, the function of my polarizing filter and the Raynox conversion lens is but ok.
Amazon also offers a magnetic holder to filter for this camera. Although the bears less burden, but also contributes significantly less.
