Why you can trust TechRadar We spend hours testing every product or service we review, so you can be sure you’re buying the best. Find out more about how we test.
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.
While JPEG images from the Samsung NX200 produce better results than those produced by the smaller sensor of the Nikon V1, up to a sensitivity of ISO 3200 it is out performed by both the Olympus E-PL3 and Sony NEX-5N.
