One reason I did not upgrade from the D300 to the D7000 was
the "feel" of the camera. For me, the feel is
different - the D7000 was too small in my hands. The D600
feels "small" compared to my D800.
The large filesizes for the D800 are a problem in that it is
timeconsuming to open in lightroom, etc. Something I found
is that for general people shoots using the jpeg medium is
fine. You do not need all the detail in the faces.
