Pentax Optio Z10 - 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 ISO setting has been reduced to let you see the full image, and below that 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 64 ISO the image quality is quite good.

----



At just ISO 100 however there is some sign of image noise.

----



Slightly more noise at ISO 200, with colour mottling in the lighter areas.

----



At ISO 400 there is visible noise right across the image.

----



At ISO 800 there appears to be less colour noise, but only because it is overwhelmed by the luminance noise and loss of saturation.

----



Both chromatic and luminance noise at ISO 1600.

----



Why bother having an ISO 3200 setting when the image quality is this poor?

----



This is the full frame at ISO 3200.
