Rayqual Mount Adapter LM-NZ (Lens) Leica M - (Camera) Nikon Z (Made in Japan) Purchased new in March 2025. In beautiful condition due to infrequent use. Not much information is available, but the product itself is lightweight at 55g. I think the sense of unity with the Z body when attaching M-mount lenses is better than other mount adapters. No helicoid included. Feel free to comment if you have any questions.
