Metabones Leica R to Fuji X Speed Booster brand_Pana-Vue if you just threw awayA genuine Metabones Speed Booster adapter to mount Leica R SLR lenses to Fuji X mount cameras. A Speed Booster slightly reduces the crop of your lenses (from 2x to about 1. 5x) and adds an extra stop of light, to boot. Not a bad bargain! In very good cosmetic condition, with minor wear; optics and function are excellent.
