KiponAuto Focus AF Adapter for Canon EOS EF Lens to Fuji GFX Camera EF-GFX AF

Fast auto focus for my GFX machine, i have tested EF70-200 f2.8，EF70-200 f4，EF 50 1.4，EF70-300.all work good.

I came from the viltrox adaptor. That one worked but maybe 30-40% hit rate. This adaptor with the same lenses gets about 60-70% hit rate. Used on a gfx50r. Shot a coupon weddings using this adaptor with sigma 50mm F1.4, canon 85mm F1.2, canon 135mm f2. They are all but hit rate will differ depends on the lens. Same goes with AF speed.
