Pentax Optio RS1000 - Test Shots - ISO Performance

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 shaded natural light.

Noise effects are more noticeable at 200 ISO.

At 400 ISO the noise reduction has seriously reduced fine detail.

Picture quality dives even further at 800 ISO.
