The fourth image is an example of the adapter in use. The body and lens are not included. This is a lens adapter from Focus Camera. It allows you to mount Leica M-mount lenses on SL-mount bodies such as those from LUMIX and SIGMA. It has a built-in helicoid, so even lenses with a minimum focusing distance of around 70cm can focus much closer. The Type 2 version allows for even closer focusing. It is sold on Amazon for 27,000 yen. There are no issues with its operation.
