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.
A high signal to noise ratio (SNR) indicates a cleaner and better quality image.
JPEG Signal to noise ratio
RAW Signal to noise ratio
Converted RAW files from the Olympus E-PL3 show a better signal to noise ratio than the Panasonic Lumix GF3, Samsung NX11 and Sony NEX-C3 above ISO 200, showing the Olympus E-PL3 produces cleaner and more detailed images.
JPEG Dynamic range
RAW Dynamic range
This chart indicates that the Olympus E-PL3's converted Raw files have a at least a 1EV higher dynamic range than the Panasonic Lumix GF3 and the Samsung NX11, and compare well against the Sony NEX-C3.
