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

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

For more more details on how to interpret our test data, check out our full explanation of our noise and dynamic range tests.

Nikon 1 J2 review

JPEG images from the Nikon 1 J2 show better signal to noise ratio results than the original Nikon 1 J1 throughout the whole sensitivity range, but sit below those of the Sony NEX-5R at every sensitivity setting but ISO 1600. The Panasonic GF5 starts of with a greater signal to noise ratio than the Nikon 1 J2 at lower ISOs, but falls below its results at ISO 800, where the Nikon 1 J2's results improve for a while, as the other cameras' all steadily fall.

Raw signal to noise ratio

Nikon 1 J2 review

TIFF images (after conversion from raw) from the Nikon 1 J2 show a more uniform picture, with the Nikon 1 J1 again beating the original Nikon 1 J1 for signal to noise ratio, but sitting below the Sony NEX-5R. The Panasonic GF5 is again better at ISO 200, but produces worse results after that.

Dynamic range

Nikon 1 J2 review

This chart indicates that dynamic range in the Nikon 1 J2's JPEGs is better than the Nikon 1 J1, Sony NEX-5R and Panasonic GF5 at most sensitivities. It falls below the Panasonic GF5 at ISO 400, and matches the Sony NEX-5R at ISO 100, but otherwise outperforms them.

Raw dynamic range

Nikon 1 J2 review

TIFF/raw images from the Nikon 1 J2 show a greater variation in dynamic range scores, but are still ahead of those from the Nikon 1 J1 and Panasonic GF5. The Sony NEX-5R produces superior dynamic range in its raw images. There's no overlap between the Nikon 1 J2 and any of the other cameras in this chart.
