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.
JPEG signal to noise ratio
In terms of signal to noise ratio, the V3 fares worst compared with the other cameras on chart, including its predecessor, the V2. Here we can see that the Panasonic GM1 is actually the best performer on the chart - it's worth noting that the GM1 has a much larger sensor. As the V3 features an AA filterless design, the results here could be an indication of detail resolution being favoured over noise reduction.
Raw signal to noise ratio
Again, it is the V3 which performs worst on this chart when compared with the other cameras on test. The line follows a similar progress to the V2's, but again, puts in a worse performance. This can probably also be attributed to the design of the sensor producing more detail than previously. For raw format images, the Panasonic GM1 performs best for low to mid-range sensitivities (ISO 200 - 800), from where the Samsung NX Mini and the Nikon V2 take over.
JPEG dynamic range
The Nikon V3 puts in quite a flat performance for JPEG dynamic range, which is reflected in real world shooting by images with a pleasingly warm appearance. It fares worse than all of the other cameras on test though, including its predecessor, the Nikon V2. It is the Panasonic GM1 and the Samsung NX Mini which are the best performers here.
Raw dynamic range
Again we can see that for raw format images, the Nikon V3 fares worse than its comparison cameras, one of which is its predecessor, the V2. Here we can see that the Panasonic GM1 performs the best throughout the majority of the sensitivity range, being over taken at the higher scores by the Samsung NX Mini.
