We test the new 400D digital camera for image noise in two daytime situations.
The new 400D/Rebel XTi is the next step in Canon’s entry-level dSLR digital camera lineup.
The RAW files for this and the other tests are available from our Camera Test page.
below JPEGs are 100% crops (i.e. the actual pixels) from the center of
the image prepared from the RAW file with no sharpening, noise
reduction or exposure adjustment done through Adobe Camera RAW and
Please note also that these are the worse case noise levels you should see. In practice all images, even from RAW, will have some noise reduction applied to them in the conversion process.

Daytime tests with our usual subject matter:
100ISO 1/125 f4
200ISO 1/125 f5.6
400ISO 1/125 f8
800ISO 1/125 f11
1600ISO 1/125 f16
Daytime tests with our new less-cluttered subject matter:
100ISO 1/500 f5
200ISO 1/500 f7.1
400ISO 1/500 f10
800ISO 1/500 f14
1600ISO 1/500 f20
Image noise is quite well controlled through to 800ISO but quite heavy at 1600ISO.
