I would very much like to see any results you get from testing a 600mm. Jim, Just pointing out there are manual focus 600mm Nikkors. Rafael's 800mm examples are wonderful, and I have over 20K images with and without teleconverters. If you are into tinkering, you can modify a Nikon TC-16a to give partial AF to a manual focus lens. You get it close by hand, then the TC has elements that are driven by the camera to fine tune the focus (F mount only). Or, you can use a focus confirmation adapter on many bodies.
These are great.
