Sony Cyber-shot DSC-W200 - Test shots - ISO performance
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 100 ISO the sheer power of the 12MP sensor and pin-sharp Zeiss lens produces a huge amount of detail, with not a trace of noise.
Still no real problems at 200 ISO.
However at 400 ISO the smoothness of the image and the level of detail are starting to fade, and there is some colour mottling.
At 800 ISO the effects of noise and noise reduction are clearly visible, with smudged detail and uneven colour.
Worse still at 1600 ISO.
The image quality at 3200 ISO is quite low, and there was significant colour distortion ove large areas of the image.
The full frame at maximum ISO.
