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. These pictures were taken indoors using reflected natural light


This is the full frame at 80 ISO.


At the minimum ISO setting the picture quality is excellent, with smooth colours and plenty of detail.


Almost the same results at 100 ISO.


200 ISO and the image quality is still superb.


It all starts to go wrong for the T900 at 400 ISO, with distorted colour, lost detail and visible noise.


800 ISO is even more blotchy and noisy.


1600 ISO and lots of detail has been lost to the noise reduction.


3200 ISO is available at full resolution, but the picture quality is pretty terrible.


This is the full frame at 3200 ISO.

There are internet shops that appear to be selling this camera for £75 less than the 'as reviewed' price. I'd suggest Google :).

This thing has a lens that starts at f 3.5 at best on 35mm as the wides setting available? Thats really poor. No wonder the ouptut is so bad. Even my Canon SD780 has a bit better than that. And its no superstar camera itself

Dear Cliff

Where is your review for Sony HX1.

Is it still over priced if I can buy it for £220?

I love this camera. But want to get the best bang for buck as the Yanks say!
