Nikon Coolpix P7100 review

We shoot a specially designed chart in carefully controlled conditions, and the resulting images are analysed using the DXO Analyzer software to generate the graphs below.

Signal to noise ratio

Our lab results from the Nikon Coolpix P7100 show that there is an improvement over the Nikon Coolpix P7000 for signal to noise ratio, and these results are also better than those produced by the Canon PowerShot G12 and Olympus XZ-1. These results show that the Nikon P7100 handles noise well, with less noise in images across the sensitivity range than the comparison cameras.

A high signal to noise ratio (SNR) indicates a cleaner and better quality image.

JPEG images from the Nikon Coolpix P7100 show improved noise performance over the Nikon Coolpix P7000 and are on a par with those from the Canon PowerShot G12 and Olympus XZ-1

After conversion to TIFF, raw images from the Nikon Coolpix P7100 show improved noise performance over the Nikon Coolpix P7000, Canon PowerShot G12and Olympus XZ-1

Dynamic range

When it comes to dynamic range there is only a marginal improvement over the Nikon Coolpix P7000, and while it cannot match the Canon PowerShot G12 and Olympus XZ-1 its performance is still better than average, showing that it's capable of capturing a good amount of both shadow and highlight detail across the sensitivity range.

This chart indicates that the Nikon Coolpix P7100's JPEG dynamic range relates closely to the Nikon Coolpix P7000, but it cannot match the Canon PowerShot G12 and Olympus XZ-1.

This chart indicates that the Nikon Coolpix P7100's raw files (after conversion to TIFF) dynamic range is an improvement over the Nikon Coolpix P7000, and beats both the Canon PowerShot G12 and Olympus XZ-1 at sensitivities over around ISO 200.
