Canon PowerShot A720 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 a full-frame image at the minimum sensitivity of 80 ISO.
Image quality at the lowest ISO setting is superb.
Not surprisingly image quality is unchanged at 100 ISO.
Still no trace of noise at 200 ISO.
There is a little luminance noise at 400 ISO, but it is barely noticeable.
Noise is a bit more prevalent at 800 ISO, but the image is still printable.
Some fine detail has been lost at 1600 ISO, but the overall image quality is still surprisingly good.
This is the full-frame image at the maximum ISO setting of 1600.
