newyi LM-gfx Mount Adapter This adapter allows you to mount Leica M-mount lenses on Fujifilm GFX bodies. I purchased this new this year and used it a few times on a GFX50S II. I believe there are no issues with precision or looseness, but I haven't tested it on all compatible models, so it might vary slightly depending on your specific camera. There appear to be no noticeable scratches. Mount Adapter SHOTEN Kipon Leica M GF Mount
