Mount adapter made by Kani Koubou Leica M mount lens → Sony E mount conversion With helicoid Purchased in August of this year, I am selling this as I have purchased a higher-end model with an infinity focus stop. ● Equipped with a 5mm extension helicoid, which shortens the minimum focusing distance. Allows for close-up photography with Leica M mount lenses. There are no visible scratches or stains, but it is a used item that has been used for about two months. Please purchase only if you understand the current condition.
