Hi, first of all sorry for my bad English. I've just received my brand new 17mm 1.8 and i realized some kind of "malfunctioning" Here are the steps: 1: Set the camera in MF mode 2: put the lens focus ring in AF position 3: try to focus an object as close as possible 4: put the lens focus ring in MF position 5: now try to focus on the same objet as before. With my lens i'm unable to do it at the same distance, I have to move backward and give more distance to be able to focus the same object . Is it normal that the minimun focus distance is higher with the focus ring in MF than in AF position? Even when the camera is set in MF all the time? Is my lens a defective one? Here are two pictures, with the ring in AF position I can focus on the first leaf, while in MF position it's impossible.
