Mount adapter. This is a listing for the HAWK'S FACTORY L-M MH TO E adapter with helicoid. This adapter allows you to attach Leica M-mount compatible lenses to Sony E-mount cameras. It features a built-in auxiliary helicoid, enabling macro photography with Leica lenses. This is an early model from before the renewal, so it is considered rare. I used it with a Summilux attached to a NEX5. A front cap is included. Please check the last photo. ○Exterior There are slight scuffs on the lens contact surface (which will inevitably occur with use), but it is clean due to infrequent use. ○Operation No problems. *This confirmation of attachment and use is based on a NEX5. We cannot guarantee against malfunctions on other series. We apologize, but returns will not be accepted. *There may be oversights other than those mentioned above, but please forgive me as I am an amateur. *Due to the nature of used items, scratches, signs of use, and appearance may vary depending on individual perception. *We ask that you purchase this item with no claims and no returns, understanding that it is a used product. *Only the adapter is being sold; photographic accessories are not included. *Please purchase after fully understanding the contents.
