Pentax Optio V20 - 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.

/94/eb8eed/ef85/7939-PentaxV20ISO80.jpg

Image quality is very good at 80 ISO, with smooth texture and excellent detail.

----

/94/1bfaee/0652/7939-PentaxV20ISO100.jpg

There is very slight colour mottling at 100 ISO, but overall quality is still very good.

----

/94/84a100/789d/7939-PentaxV20ISO200.jpg

There is slight noise reduction blurring at 200 ISO, but not enough to cause a problem.

----

/94/1e56ba/104e/7939-PentaxV20ISO400.jpg

400 ISO and there is still plenty of fine detail, although there are signs of noise in the green areas.

----

/94/804385/2364/7939-PentaxV20ISO800.jpg

At 800 ISO the noise reduction really goes to work, and a lot of fine detail is scrubbed out.

----

/94/a34885/10e9/7939-PentaxV20ISO1600.jpg

Image quality is greatly reduced at 1600 ISO.

----

/94/e8d249/679f/7939-PentaxV20ISO3200.jpg

3200 ISO is limited to 5MP, and image quality is very poor.

----

/94/3acbf4/775d/7939-PentaxV20ISO6400.jpg

6400 ISO at 5MP, and it looks like a still from YouTube.

----

/94/f87ddc/2284/7939-PentaxV20ISOmax.jpg

This is the full frame at the maximum ISO setting.
