Why you can trust TechRadar
These graphs were produced using data generated by DXO Analyzer.
We shoot a specially designed chart in carefully controlled conditions and the resulting images are analysed using the DXO software.
Signal to noise ratio
A high signal to noise ratio (SNR) indicates a cleaner and better quality image.
JPEG images from the Sony NEX-5n show slightly better signal to noise ratio results than the Sony NEX-5 and the Olympus E-PL3. From a sensitivity of ISO 400 and above the Sony NEX-5n also shows better noise performance than the Panasonic Lumix DMC-G3.
Raw signal to noise ratio
Raw images (after conversion to TIFF) from the Sony NEX-5n shows a better signal to noise ratio across the sensitivity range than the Sony NEX-5 and the Panasonic Lumix DMC-G3 and just beat the Olympus E-PL3 from a sensitivity of ISO 3200.

This chart shows that the Sony NEX-5n's JPEGs capture a wide tonal range across the sensitivity range. Although there is a steep drop from ISO 3200, the tonal separation is still good.
Raw dynamic range
This chart indicates that the Sony NEX-5n's raw images (after conversion to TIFF) capture a wide tonal range across the sensitivity range, beating the Sony NEX-5, Olympus E-PL3 and Panasonic Lumix DMC-G3 by at least 1ev.
