Since Nikon Df's has a larger sensor area with the same resolution, this means that it also has a larger pixel area hence better light collecting capacity for a given aperture compared to Nikon D7000.
Below you can see the D7000 and Df sensor size comparison.
As seen above, Nikon Df has a 2.3x Larger sensor area than Nikon D7000. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
DxOMark Sensor Scores
DxOMark is a benchmark that scientifically assesses image quality of camera sensors. It scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Nikon D7000 and Nikon Df sensors have been tested by DxO and the results show that Df has a better overall score of 89, 9 points higher compared to D7000's score of 80.
