Compared to the 10 mega-pixels sensor used in the D40x, D80, and the D200, which were all available at the same, it has a lower noise level due to its lesser pixel-density. So what makes this “little” DSLR so capable? First of all, it 6 mega-pixels sensor, though having a relatively lower resolution than its competitors at the time of introduction, has been well-proven for its quality from the earlier D50 and D70 (and possibly also the D100). This is of course bad news for those Nikon users who are switching from film to digital because the D40, despite all the simplifications mentioned above, is a very capable body with an affordable price tag.

I believe Nikon removed the in-body AF motor because they think most D40 users are beginner photographers and/or first-time DSLR buyers who would probably be using their new line of AF-S DX lenses rather than old AF lenese from the film-era. The last change makes the D40 unable to autofocus with the older AF and AF-D lenses though an in-viewfinder focusing aid is still provided by the camera’s electronic rangefinder. The “miniaturization” include omission of the top LCD display, the use of penta-mirror instead of penta-prism for the viewfinder, a smaller battery, and most distinctively, the removal of the in-body screw-driver AF motor. It is the first “miniaturized” DSLR body from Nikon. Nikon D40 is 6 mega-pixels APS-C sensor DSLR introduced in late 2006.
