Over the next few pages we show a range of test shots. On this page the full size image at the minimum and maximum ISO settings have been reduced to let you see the full image, and a series of full resolution crops have taken from original images at a range of ISO settings to show the overall image quality.

Full-frame image at minimum ISO.

Even at the minimum ISO 64 there is some colour noise visible, as well as compression artefacts.

Both noise and compression are more visible at ISO 100.

Noise reduction has cleaned up some of the colour speckling at ISO 200, but there are still patches of distorted colour.

At ISO 400 the noise reduction is starting to blur out the fine details.

At ISO 800 the shot is suddenly marred by some bizarre colour distortions. I've included the full image below to show the effects.

Is this colour distortion at ISO 800 related to the technical problem that caused the camera to crash?

At ISO 1600 the image quality is very low, with poor colour and little fine detail.

This is the full frame at ISO 1600.
