Nikon D7100 review

Superseded by the D7200 but still on sale, the Nikon D7100 now looks a good value buy

The signal to noise ratio data shows how much of the camera's image is made up of real image data and how much is random noise. The higher the signal to noise ratio figure, the better, because this means the image exhibits less noise.

JPEG signal to noise ratio analysis: The D7100's results are very close to those of the newer Canon 760D and Pentax K-S2, which is a creditable performance for an older camera. Interestingly, the D7200's figures are a good deal lower. This suggests that Nikon has modified the image processing to favour resolution over noise – this seems to be borne out by its unusually high resolution results. Many photographers would probably accept more noise if it meant sharper detail.

Raw (converted to TIFF) signal to noise ratio analysis: This pattern is repeated with raw files – the D7100 competes well with the Canon 760D and Pentax K-S2, while the D7200 lags a little behind.
