Both Nikon D7100 and Nikon D7200 have 24.0 MP resolution sensors but Nikon D7100's sensor is APS-C (23.5 x 15.6 mm ) and Nikon D7200's sensor is APS-C (23.5 x 15.6 mm ).
Since Nikon D7200'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 D7100.
Another similarity between these two cameras is that both Nikon D7200 and Nikon D7100 sensors lack anti-alias (Low-Pass) filters. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moiré occurring in certain scenes.
Below you can see the D7100 and D7200 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon D7100 and Nikon D7200 Cameras
Nikon D7100 and Nikon D7200 have the same sensor sizes so they will provide same level of control over the depth of field when used with 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 D7100 and Nikon D7200 sensors have been tested by DxO and the results show that D7200 has a better overall score of 87, 4 points higher compared to D7100's score of 83.
