Re: It bounds AF precision

I have no doubt that it is a difficult problem, especially with the lack of available information on the Nikon AF sensor, but I thought that with some reasonable assumptions we could do better than just saying, as some on the Internet are wont to do, "That is a bad autofocus target" or "Good autofocus cannot be achieved with that image".
