Canon PowerShot A470 - 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.

At the minimum sensitivity setting the image quality is very good, with little sign of noise.

Almost identical results at 100 ISO.

Noise is starting to creep in at 200 ISO, but overall quality remains good.

At 400 ISO noise is plainly visible, but overall colour rendition is still pretty good.
