Nikon D40x
Announced in March 2007 just a few months after the D40, this camera ups the D40’s resolution to a sharp 10 megapixels. Another improvement over the D40 is a bright (but still rather small) optical viewfinder. All in all, this camera is just what one might hope for: very easy to use and plenty of bang for the buck.
The major compromises of the D40 remain, however: no auto-focus for F-mount lenses except AF-S and AF-I models, no display on top of the body, and the lightweight body doesn’t impress knock-about professionals.

…just as good as the D40, with the added benefit of a little bit more resolution and slightly faster continuous shooting…
…a very capable camera, but its higher price point makes you more critical of the weaker aspects inherited from the D40.
To say that Nikon and Canon are in competition with one another is something of an understatement. They are the Manchester United and Arsenal, the Schumacher and Alonso, the Tyson and Holyfield of the camera world. They
The original D40 was Nikon’s entry level DSLR, but with a paltry 6Mp resolution it was starting to look sickly in comparison to the robust Canon EOS 400D entry level model that boasted 10Mp. One quick re-engineering job later and here’s the D40x.
The camera body itself is on the small side, keeping in line with most of the entry-level dSLRs on the market. It has a well-formed grip, with a slight indentation on the inside that adds to its solid feel, though like the smaller Pentax models and the Canon EOS 400D, your pinky finger is likely to dangle below the camera.
The D40X is a lightweight and portable camera that proves that it can be both incredibly simple and tremendous fun to shoot images with a Nikon digital SLR. You only need to turn on the camera’s AUTO mode, look through the clear, bright viewfinder and shoot
All key specification, the controls, the handling, the large LCD and its neat graphical user interface via the big screen are the same. Even the gross body weight (including the (same as D40) battery) is identical at 522g.
Very light and simple to use. Well featured and with an excellent rear screen display that is easy to see/use even in bright light. Very good white balance control which does a good job on auto and an even better one when set to the specific light type.
The original D40 brought ease-of-use and a comfortable compact body to the D-SLR world, and it was a welcome development. It offered a solid design, great photo quality, a very user-friendly menu system, and the kind of performance that you’d expect from a digital SLR.
Nikon says the D40x is therefore designed as a step-up for anyone who loved the D40 but was put off by its lower resolution, although clearly it’s also now a direct rival for Canon’s massively successful EOS 400D / XTi.
