Thank you for viewing. This is a mount adapter for attaching Leica M-mount lenses to Sony E-mount cameras. It came with a lens I purchased, but I don't need it, so I'm selling it. I don't own an E-mount camera, so I haven't been able to confirm its functionality through shooting, but it appears to be in good condition without any visible deformation. Photos 5, 6, and 7 are reference photos showing lenses attached. The item for sale in this listing is only the M-mount lens to E-mount body mount adapter.
