”Over the next few pages we show a range of test shots. On this page the full size image at the minimum ISO setting has been reduced to let you see the full image, and below that a series of full resolution crops have taken from original images at a range of ISO settings to show the overall image quality.”
At the minimum 64 ISO the image quality is quite good.
At just ISO 100 however there is some sign of image noise.
Slightly more noise at ISO 200, with colour mottling in the lighter areas.
At ISO 400 there is visible noise right across the image.
At ISO 800 there appears to be less colour noise, but only because it is overwhelmed by the luminance noise and loss of saturation.
Both chromatic and luminance noise at ISO 1600.
Why bother having an ISO 3200 setting when the image quality is this poor?
This is the full frame at ISO 3200.
