Wasting no time at all, Olympus has updated its Pen E-P1 camera just five months after it was released. Richard Sibley tests the Olympus Pen E-P2 to find out what has been changed
Resolution, noise and sensitivity
These images show 72ppi sections of images of a resolution chart, still-life scene and a grey card. We show the section of the resolution chart where the camera starts to fail to reproduce the lines separately. The higher the number visible in these images, the better the camera’s detail resolution is at the specified sensitivity setting.
With the same sensor as the E-P1, the resolution and noise levels of the E-P2 remain similar. At ISO 100 it can reach nearly 24 on our resolution test chart.
There is a big drop in quality when it reaches it reaches ISO 800. This is clearly the point at which high ISO noise reduction kicks in, as there is no visible noise but detail is lost due to smudging.
Results from raw files are much the same, with noise well controlled up to around ISO 400. By ISO 800, luminance noise is visible but still unobtrusive.
At ISO 1600 and above, both colour and luminance noise are present, although it is beneficial to keep luminance noise reduction to a minimum to avoid the slight blurring that is seen is JPEG files.
