This is a HAWKS FACTORY mount adapter, L/M - SONY E MH. I am selling it to organize my dehumidifying cabinet. This adapter is for attaching Leica M lenses to Sony E-mount bodies. I used it on my α7 III. It is a used item as shown in the images. It works without any problems. Please consider purchasing if you are not overly concerned about minor imperfections.
