A range of test shots are shown over the next few pages. Here, the full size image at the minimum ISO setting has been reduced for bandwidth purposes to let you see the full image, and a series of crops taken from original full resolution images at a range of ISO settings have been placed below it in order for you to gain an appreciation of the overall quality.



At 100 ISO the D40x produces beautifully smooth, well detailed shots, as one might expect.


Likewise at 200 ISO.


Still no problems at 400 ISO


800 ISO and still no noise. Compare this to the test shots from the EOS 400D.


At the maximum 1600 ISO there is just a light speckling of image noise, but this would still look good as an A4 print.

Hi Cliff

I'm considering purchasing either this D40 or the Sony A200. I notice that you have given the Sony A200 9 points, while this one has been rated 10. What made you give the D40 one more point than the A200?
