This is the TECHART LM-EA9 electronic mount adapter. It's an adapter that allows you to mount Leica M-mount lenses on Sony α E-mount cameras and achieve autofocus. This is the Mark 1 model. By stacking other mount adapters on top of this LM-EA9, you can magically enable autofocus for old manual lenses other than Leica M-mount lenses. It's practically like new with almost no scratches, so please consider this opportunity! Operation has been confirmed.
