Under lab conditions, we shoot three charts with each camera to assess sensor performance with visual and computer analysis. Dynamic range and noise are measured with the DxO transmission chart. Images of this chart are processed in DxO Analyser.
Colour error is measured using the X-Rite ColorChecker chart. We also shoot a resolution chart, indicating the detail each camera is able to record in LW/PH.
Dynamic range result: The E-PM1 produces consistently high dynamic range. The GF3 and Samsung NX11 lag behind the rest of the group at higher sensitivities.
