I had heard some comments that the D7000 was slow to focus, never had that problem though. I think it's slightly better than my D300 on first try.
Here's a few with some info:-

1/200th @ 300mm

1/200th @ 300mm

1/200th @ 500mm

1/200th @ 350mm

1/100th @ 150mm

Into sun 1/125th @ 400mm

Into sun 1/125th @ 300mm

Into sun 1/125th @ 300mm
It got a bit silly then:-

Into sun 1/80th @ 500mm - not quite sharp enough but not too bad.
Finally

1/125th @ 500mm
Not a bad start, just more practice handling the larger lens I think.
C&C welcome.
