I have been watching the DPR about the focus issues with the MK3. This morning I find THIS thread. A few observations.... If Nikon came out with a body with micro AF adjustment the first thing I would do is test and adjust the most commonly used lenses. From the DPR I get the feeling that they do not want to, or feel there should be no need to. They keep comparing it to other C bodies. It seems to me that the AF in the MK3 is a different animal and must be treated as such. After reading that first post I am left with a question. Does the MK3 not have an AF-ON button?
