This is a mount adapter made by EAYQUAL that allows you to use Leica M mount lenses on Sony mirrorless cameras like the α7. It does not have an extending helicoid. There is a small paint chip on the body-side mount claw, but otherwise, it is in excellent condition with no scratches or scuffs. —-Automatically generated text below—- RAYQUAL metal mount adapter, LM-SαE model. - Brand: RAYQUAL - Model: LM-SαE - Type: Mount Adapter - Color: Black - Features: Metal construction, durable Thank you for viewing.
