Thanks for the info. I am trying to find settings for different types of scenarios, for example, ones that will allow me to pan the camera across a landscape and retain focus - probably a difficult task. I tried this with the D7000 and a 70 - 300 (newest) lens and even with a very slow pan of my neighborhood, the lens did a lot of searching and the green rectangle in the viewfinder was hard to maintain. I wonder if that is as good as it will get (my old Sony CX 520 camcorder could do this effortlessly... what are the main differences?)
I assume subject tracking would be used for a different scenario.
I wonder if (and when) Nikonians establishes a Video group, we could have a sticky thread that lays out all the best settings for a variety of scenes. Anyone want to start the process? Best, Dennis
