The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The Nikon D40 was launched in the US market at a price of $499. Usually, retail prices stay at first close to the launch price, but after several months, discounts become available. Later in the product cycle and, in particular, when the replacement model is about to appear, further discounting and stock clearance sales often push the camera price considerably down. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison with a 35mm slide
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels in a sensor of the same technological generation. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the background. On the downside, larger sensors are more costly to manufacture and tent to lead to bigger and heavier cameras and lenses.
The Nikon D40 features an APS-C sensor and has a format factor (sometimes also referred to as "crop factor") of 1.5. Within the spectrum of camera sensors, this places the Nikon D40 among the medium-sized sensor cameras that aim to strike a balance between image quality and portability.
For most cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

It should be noted that unlike many modern cameras, the D40 does not provide the possibility to capture videos.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the D40 has an optical viewfinder that provides a field of view of 95% and a magnification of 0.53x. The adjacent tables list some of the other core features of the Nikon D40 along with similar information for a selection of comparators.
One convenient feature of the D40 is the presence of an on-board flash. While this built-in flash is not very powerful, it can at times be useful as a fill-in light to brighten deep shadow areas.
For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process. The table below provides an overview of the connectivity of the Nikon D40 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

While the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the D40. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
Nikon D40 FAQ
Below are some additional questions and answers concerning some particular features of the D40.
What technology is the imaging sensor in the D40 based on?
The camera features a CCD (Charged Coupled Device) sensor.
What is the ISO sensitivity range of the D40?
The camera has a native sensitivity range from ISO 200 to ISO 1600.
What is the life expectancy of the shutter in the Nikon D40?
Nikon mentions a shutter rating of 50 000 actuations for the D40. This number represents a Mean Time before Failure, that is an average value. The shutter might fail earlier, or it might last longer. Anyway, in order to exhaust the expected shutter life of the D40 over, say, three years, one would have to take about 50 pictures each and every day.
How do I find the shutter count on my Nikon D40?
Nikon embeds the number of shutter actuations in image metadata. You can check the number of shots that your D40 has taken up to now by uploading a recent image to the online shutter count app.
Does the Nikon D40 feature an autofocus assist light?
Yes, the camera has a lamp built-in that can illuminate the subject and improve autofocus in low-light settings.
What is the fastest shutter speed that can be used with flash?
The D40's flash sync speed is 1/500 sec.
Which battery does the D40 use?
The camera gets its power from the EN-EL9 (here at amazon), which is a rechargeable Lithium-Ion power pack.
Is there a vertical grip available for the D40?
Nikon does not offer an optional battery grip, but third party suppliers do (see here on eBay).
