For me, less trigger movement means less camera shake. Which means the D7000 is a more "responsive" camera. Like a sports car, responsive doesn't mean comfortable. It's designed to get your heart racing and your nerves pumping, man!
And a beginning driver in a sports car? Not.
Slow down, breathe easy, out, in, out in, out, half in and hold, squeeze between heart beats... wait, that's something else.
