There were indeed problems with certain iterations of the D7000 as 'some" were over enthusiastically oiled in their mirror chamber which occasionally splashed small oil droplets on the sensor. I had one and it was quickly fixed by replacing the mirror chamber. That said I found the sensor very satisfactory, the auto focus less so. I never had rain leakage, but and this is subjective, it did not feel as weather resistant as my D300 which I dragged from Beijing to Chile.I do hope they make the mode dial a bit less subject to movement when it brushes against the camera bag. Both the D300 and the D7000 struggled in lowlight and above 1600 ISO . Since I am not a sports shooter but someone interested in travel and street photography, fps is not as important as focus accuracy and single point center focus has served me well. The dream of a quality full frame sensor on a "durable" Nikon body at a reasonable price that allows both DX and FX lens choice is a "siren call " I can not ignore.I do expect a larger "DR' and more" Raw Headroom."
