But it may not be strategically possible for Nikon to allow such upgrade to be performed. I believe that there are no difference in the optical formula of MF, AF or AF-D for the comparable lenses (such as 105 MF micro, 105 AF micro or 105 AF-D micro). The difference lies in the exposure calculation, between Center-Weighted for MF, Matrix for AF and Matrix 3D for AF-D. But if you're like other professional photographer that use extensive exposure bracketing, then the difference between exposure calculation methods is offset by the bracketing, and you may stay with your trusted F4. The Matrix 3D is showing its usefulness if your subject is always changing in split-second (such as wedding or photojournalism), where there are no time to do bracketing. Matrix 3D has nothing to do with the optical quality of your lenses, whether it is Non-AI, AI, AIS, MF, AF, or AF-D. >" I cried because I had no shoes, >until I met a man who had no class."
