We test the Nikon D40x for image noise as we vary the ISO
The Nikon D40x is a nice little camera. Very functional, it fits the hand well and takes great shots. For this test we shot in daylight as we varied the ISO.
The images below are 100% crops from the center of the image. The complete NEF (RAW) files are available from the camera test page.
100ISO – 1/200 f7.1
200ISO – 1/250 f8
400ISO – 1/320 f10
800ISO – 1/500 f11
1600ISO – 1/800 f14
3200ISO – 1/1000 f16
Noise levels are very well controlled at 100 to 400ISO, become noticeable at 800ISO and far too high at 3200ISO.
