However, the AF function for macro is seldom satisfying. One of the reasons is that when you are at 1:1 (true macro) AF does not work well and the lens will "hunt focus". The reason is that AF technology depends on contrasty parts of the scene to autofocus.... By definition macro subjects often do not provide the type of scene where AF works at an optimal level. I seldom use AF....
I agree with this. Often the subject matter is not distinct enough for an AF lock where you want it or hunting for focus occurs. That said, I have the 60mm AF and the 105mm AF-S and they both produce spectacular results. I often use a CamRanger in Macro since I can specify the area I want in focus by pointing to it on the image display. In addition to that I can automatically run an incremental focus series and stack the images in Photoshop making some unimaginable shots of static subject matter.
