Thank you for viewing. SHOTEN LM-SE M II (Leica M mount lens to Sony E mount conversion) with helicoid mount adapter, black ・Compatible lens mount: Leica M ・Compatible camera mount: Sony E ・With helicoid function I am selling this because I changed mounts when I upgraded my camera and no longer need it. I purchased it several years ago and used it a few times, so there are some minor scratches on the mount surface, but it is generally in good condition. Please note that returns and exchanges are not accepted for used items.
