A range of test shots are shown over the next few pages. Here, the full size image at the minimum ISO setting has been reduced for bandwidth purposes to let you see the full image, and a series of crops taken from original full resolution images at a range of ISO settings have been placed below it in order for you to gain an appreciation of the overall quality.

At the minimum ISO setting of 80 the image quality isn't too bad, with little visible noise.

Up one stop to 160 ISO and already there is image noise visible. Also note the slightly different exposure, despite the identical conditions.

At 320 ISO the image noise is worse, colour rendition is off and fine detail is lost.

Not much difference at 400 ISO, but then it's only a third of a stop faster.

At 800 ISO image quality is extremely poor, with little fine detail and lots of noise.

At the maximum setting of 1250 ISO the picture is unusable.
