"RE: Focus problems?"

Thom Hogan has posted Autofocus Problems, this is not in the archive so the link to the article may change, and he agrees there are some cameras with the problem and describes the problem and causes in detail along with the Nikon repair actions. The post also goes into detail about testing the different focus points and how the various sensors use phase detection to autofocus. It is interesting to note that Thom does not recommend using the Star target and implies that you may want to have more than on target on the wall if using an 8x10 print and you want your target to include both vertical and horizontal lines that are not spaced and equally and do not have equal widths. He also notes that one must have the camera parallel to the wall on which the target is located and if it is not that failure alone will cause a bad test.
