SHOTEN Mount Adapter LM-LSL M II This adapter converts Leica M mount lenses to L mount. This is the second generation model. It has a built-in helicoid, which shortens the minimum focusing distance, allowing you to take close-up shots even with lenses that don't normally focus closely. I purchased this new and used it indoors twice, but I haven't had a chance to use it since, so I'm putting it up for sale. The condition is like new, with no issues. Thank you for your consideration.
