Canon 400D/Rebel XTi Daytime Noise Tests

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.

The
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
Photoshop.

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.
