Geat alternative for metabones speed booster. Two small complaints is with canon 50mm f1.8 stm before powering on camera make sure you which the lens on auto focus or manual focus. It will not work if you want to switch from manual to af will camer is on, im sure software update will fix this problem. Second problem is if you cant focus to infinity you will need to rotate the speed booster piece of glass clockwise or counter clockwise before attaching lens so it cant focus correctly. Once its set right you dont have to mess with it, even the metabones has this issue to to time. For the price it does a great jod no loss of image quality.
