Well it has arrived and in wonderful nick! So far I am really happy with it, especially the low light! Which is what I was looking for coming from a D300.
Two things I really notice is the shutter is a lot more 'mechanical' sounding than the D300, louder in fact and a other is the control joy stick type button on the back feels loose and sloppier, it sticks up more. But obviously is because they are different cameras!
Am really looking forward to playing with this camera!! Thanks everyone for backing my gut feeling that this was the camera I wanted/needed!
