”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. These pictures were taken indoors using reflected natural light. ”
This is the full frame at 100 ISO. The shot is slightly over-exposed, because apparently the A330 takes the exposure reading before starting the self-timer countdown.
Over-exposure or not, there is no visible image noise at 100 ISO.
Still very smooth at 200 ISO.
At 400 ISO there is visible colour noise and some loss of fine detail.
At 800 ISO the colour gradient on the side of the red car is looking very rough.
1600 ISO is too noisy for serious work, but would be OK for small prints.
The same goes for 3200 ISO.
