Leica Leitz Elmar 5cm 3.5 (50mm) with Micro Four Thirds Adapter ★ There have been inquiries asking if this is a copy of a Leica lens. I do not have knowledge about that, so please make your own judgment. ★ There was also a question about whether it can be used with a Leica if the adapter is removed. I don't own a Leica, so I don't know. ① I used it occasionally with the Micro Four Thirds adapter attached. (L39 → M4/3) ② There is no mold, but there is some small dust inside the lens, but I have never felt it affected the photos. ③ I attached it to a G99 and took sample photos with it. ④ The f-stop is adjusted by turning the front ring. ⑤ Always extend the lens and then turn the knob on the front to focus. ⑥ It may look stylish when attached to a DC-GF10 in white rose gold, etc. ⑦ The items I will provide are the lens, the adapter, and the rear cap. ⑧ The last two photos show the focus knob moved to its maximum and minimum positions.
