Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D40X and the Nikon D7000? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.
The side-by-side display below illustrates the physical size and weight of the Nikon D40X and the Nikon D7000. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.
The D40X can be obtained in two different colors (black, silver), while the D7000 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D7000 is notably larger (19 percent) than the Nikon D40X. Moreover, the D7000 is substantially heavier (49 percent) than the D40X. It is noteworthy in this context that the D7000 is splash and dust-proof, while the D40X does not feature any corresponding weather-sealing.
The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Nikon Lens Catalog.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The D40X was launched at a markedly lower price (by 51 percent) than the D7000, which puts it into a different market segment. 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.
The size of the sensor inside a digital camera is one of the key determinants 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the D7000 is 1 percent smaller. They nevertheless have the same format factor of 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
Technology-wise, the D7000 uses a more advanced image processing engine (EXPEED 2) than the D40X (EXPEED), with benefits for noise reduction, color accuracy, and processing speed.
Despite having a slightly smaller sensor, the D7000 offers a higher resolution of 16.1 megapixels, compared with 10 MP of the D40X. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.80μm versus 6.11μm for the D40X). However, it should be noted that the D7000 is much more recent (by 3 years and 6 months) than the D40X, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
The resolution advantage of the Nikon D7000 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D7000 for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inches or 62.6 x 41.5 cm, for very good quality (250 dpi) 19.7 x 13.1 inches or 50.1 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.7 x 27.6 cm. The corresponding values for the Nikon D40X are 19.4 x 13 inches or 49.2 x 32.9 cm for good quality, 15.5 x 10.4 inches or 39.3 x 26.3 cm for very good quality, and 12.9 x 8.6 inches or 32.8 x 21.9 cm for excellent quality prints.
The Nikon D40X has a native sensitivity range from ISO 100 to ISO 1600, which can be extended to ISO 100-3200. The corresponding ISO settings for the Nikon D7000 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-25600.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the D7000 offers substantially better image quality than the D40X (overall score 17 points higher). The advantage is based on 1.1 bits higher color depth, 2.5 EV in additional dynamic range, and 1.2 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.
|Olympus E-420||Four Thirds||10.0||3648||2736||none||21.5||10.4||527||56|
|Panasonic L10||Four Thirds||10.0||3648||2736||none||21.3||10.8||429||55|
Many modern cameras cannot only take still pictures, but also record videos. The D7000 indeed provides for movie recording, while the D40X does not. The highest resolution format that the D7000 can use is 10800/24p.
Apart from body and sensor, cameras can and do differ across a variety of features. The D40X and the D7000 are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinder in the D7000 offers a wider field of view (100%) than the one in the D40X (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the D7000 has a higher magnification (0.63x vs 0.53x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Nikon D40X and Nikon D7000 in connection with corresponding information for a sample of similar cameras.
One feature that is present on the D7000, but is missing on the D40X is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.
The Nikon D7000 has an intervalometer built-in. This enables the photographer to capture time lapse sequences, such as flower blooming, a sunset or moon rise, without purchasing an external camera trigger and related software.
The D40X writes its imaging data to SDHC cards, while the D7000 uses SDXC cards. The D7000 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D40X only has one slot.
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 D40X and Nikon D7000 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D40X and the D7000 have been discontinued, but can regularly be found used on eBay. The D40X was replaced by the Nikon D60 , while the D7000 was followed by the Nikon D7100. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon website.
So what conclusions can be drawn? Which of the two cameras – the Nikon D40X or the Nikon D7000 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Nikon D40X:
- More compact: Is smaller (124x94mm vs 132x105mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 258g or 33 percent) and hence easier to carry around.
- More affordable: Was introduced into a lower priced category (51 percent cheaper at launch).
- More heavily discounted: Has been available for much longer (launched in March 2007).
Arguments in favor of the Nikon D7000:
- More detail: Has more megapixels (16.1 vs 10MP), which boosts linear resolution by 27%.
- Better image quality: Scores substantially higher (17 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.1 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (2.5 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (1.2 stops ISO advantage).
- Better jpgs: Has a more modern image processing engine (EXPEED 2 vs EXPEED).
- Broader imaging potential: Can capture not only stills but also 10800/24p video.
- More complete view: Has a viewfinder with a larger field of view (100% vs 95%).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.63x vs 0.53x).

- Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
- Faster burst: Shoots at higher frequency (6 vs 3 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Longer lasting: Gets more shots (1050 versus 520) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
- More modern: Reflects 3 years and 6 months of technical progress since the D40X launch.
If the count of individual advantages (bullet points above) is taken as a guide, the D7000 is the clear winner of the contest (19 : 4 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. A professional wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports shooter. Hence, the decision which camera is best and worth buying is often a very personal one.
How about other alternatives? Do the specifications of the Nikon D40X and the Nikon D7000 place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing whether the two cameras rank among the cream of the crop.
In any case, while the specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the D40X or the D7000 perform in practice. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.
This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

The review scores listed above should be treated with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time 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, please note that some of the review sites have changed their methodology and reporting over time.
