As with the majority of our studio image quality comparisons we selected the nearest competition by category, specification, price and feature set. In this case the Nikon D40X goes up against Olympus' small, lightweight ten megapixel E-410 and Canon's ever popular EOS 400D (Rebel XTi).
|Camera||Kit price||Kit lens
|Nikon D40X||$799||27 - 82.5 mm equiv.||10.2 MP CCD; 23.7 x 15.6 mm (1.5x crop)|
|Canon EOS 400D||$799||28.8 - 88 mm equiv.||10.1 MP CMOS; 22.2 x 14.8 mm (1.6x crop)|
|Olympus E-410||$799||28 - 84 mm equiv.||10.0 MP LiveMOS; 17.3 x 13 mm (4/3 format)|
For direct comparisons we always use sharp prime lenses stopped down, typically to F9 for 35 mm lenses and F6.3 for Four Thirds lenses. Here we have used the Nikon 50 mm F1.8 (it's sharper than the F1.4 at F9), Olympus 50 mm F2.0 Macro, and Canon EF 50 mm F1.4.

The Canon EOS 400D's slightly more aggressive sharpening and perhaps slightly better demosaicing deliver just a little more detail across the image, edges are better defined and some of the finer details of the Bailey's label crop are now visible (compared to the D40X). That said it would be extremely difficult to differentiate these differences in anything but the very largest print.
