K&F Concept Auto Focus Lens Mount Adapter Ring EF/EF-S to FX Electronic Lens Adapter Compatible for Canon EF EF-S Mount Lens to Fuji FX Mount Cameras

SKU: KF06.465

Is there a firmware upgrade for this adapter? I just bought one and the AF doesn't work with my Tamron 70-300mm. It works with my Canon 50mm
Answer Question
Did you find a solution to this I have the same problem?
