Stan, I use the D7000 mostly for bird shooting from a kayak. I am hand-holding the camera with a vertical grip attached and a Sigma 50-500 f/6.3 lens hanging on the end.
For me shutter speed is king. When you combined the weight of the camera and the rocking of the kayak, along with trying to keep the focus point on the head of a bird 50-100 yards away, I need to keep the shudder speed at least 1/1000. On top of that, I am often dealing with early morning light and shadows from tree cover.
The D7000 does very well. Probably remarkable. Still, if I push the ISO above 1250 and then crop the picture, I can often see noise. So, the holy grail for me is a camera like the D7000 that allows me to shoot at 1600 ISO and higher with little to no noise.
A pipe dream...probably, at least with today's technology?
