Nikon D40X has a
10.0MP APS-C (23.7 x 15.6 mm ) sized CCD sensor and features Expeed processor. On the other hand, Nikon D50 has a
6.0MP APS-C (23.7 x 15.5 mm ) sized CCD sensor .
Below you can see the D40X and D50 sensor size comparison.
Sensor Size and Resolution Comparison image of Nikon D40X and Nikon D50 Cameras
Nikon D40X and Nikon D50 have almost the same sensor size, so neither of them has any significant advantage over the other in terms of providing control over depth of field when used with the same focal length and aperture.
DxOMark Sensor Scores
Both Nikon D40X and Nikon D50 sensors have been tested by DxoMark. DxoMark scores camera sensors for color depth (DXO Portrait), dynamic range (DXO Landscape) and low-light sensitivity (DXO Sports), and also gives them an overall score. Of the two cameras that we are comparing, D40X has scored 63, 8 points higher than D50.

Sensor size sets the circle of confusion, so it drives how much depth of field each
of these bodies gives you at a given aperture. You can calculate it exactly for the
Nikon D40X
or the
Nikon D50 ,
including hyperfocal distance.
