JPEG and noise profile

JPEGs are clean through ISO 200, good though ISO 1600, and usable to ISO 6400. The extra sharpness delivered by the OLPF-free sensor helps maintain sharpness as ISO sensitivity rises.

D7100 vs. D5200, ISO 100

The D7100's images are a hair sharper than the D5200's, but much of that can be compensated for by using a better lens on the D5200 (the D7100 comes with a better kit lens). Once you equalize for that, only pixel peepers will really note a difference at low ISO sensitivities.

ISO 100

This isn't bad sharpness for a crop into a midrange distance photo.

ISO 400

The noise reduction is pretty intelligent, only kicking in when there's actually some noise to process.

ISO 800 raw vs. JPEG

Even as low as ISO 800 I could get better results processing the raw images than using the default JPEG settings. (JPEG top; raw bottom. I didn't attempt to preserve the red tint.)

ISO 1600, no noise reduction

The color noise remains fairly fine as high as ISO 1600.

ISO 1600 JPEG

You can see some of the JPEG processing and noise-reduction artifacts here, but it's okay for printing as large as 13x19.

ISO 3200, raw vs. JPEG

You can get much better results from the raw files at ISO 3200.

Color

On its default settings, the camera produces bright, saturated, pleasing colors with high contrast.

Standard vs. neutral Picture Controls

Nikon pushes the hues and contrast a little too much with its default Picture Control settings. (You can see the red hue shift here, but this example doesn't show how the contrast boost clips detail.)
