Canon PowerShot SX100 IS - 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.



This is the full frame at 80 ISO.



80 ISO, and the image quality is good, with accurate colour and no noise.



100 ISO, and still no appreciable noise.



At 200 ISO there is some noise visible in the darker areas.



Luminance noise is more noticeable at 400 ISO.



Image quality is greatly reduced at 800 ISO.



At 1600 ISO the image quality is very poor, and would not print well.



This is the full frame at 1600 ISO.
