”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.”
This is the full frame at 64 ISO.
At the minimum setting of 64 ISO the image quality is excellent, with very sharp detail.
Not much difference at 100 ISO, and image quality is still very good.
200 ISO and already there is visible image noise, particularly in the green and black areas.
Noise gets progressively worse at 400 ISO, with large random colour patches, but there is still some fine detail.
At 800 ISO the noise reduction system has blurred the image, resulting in a loss of fine detail.
At the maximum 1600 ISO image quality is very poor, with blotchy colour and little fine detail.
This is the full frame at 1600 ISO.
