”A range of test shots are shown over the next few pages. Here, the full size images at the minimum and maximum ISO settings have 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 included in order for you to gain an appreciation of the overall quality.”
This is the full frame at 100 ISO.
Not surprisingly the image is totally noise-free at 100 ISO.
No significant difference at 200 ISO.
Still no problems at 400 ISO.
There is a little noise visible at 800 ISO, but not enough to worry about.
Slightly more noise at 1600 ISO, but you could still print this.
Significant noise at 3200 ISO, but the colours are still strong and bright.
This is the full frame at 3200 ISO.
