Nikon D40X vs D50
The Nikon D40X and the Nikon D50 are two digital cameras that were announced, respectively, in March 2007 and April 2005. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The D40X has a resolution of 10 megapixels, whereas the D50 provides 6 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D40X and the Nikon D50? 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 physical size and weight of the Nikon D40X and the Nikon D50 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.
The D40X can be obtained in two different colors (black, silver), while the D50 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 D50 is notably larger (16 percent) than the Nikon D40X. Moreover, the D50 is markedly heavier (19 percent) than the D40X. In this context, it is worth noting that neither the D40X nor the D50 are weather-sealed.
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 adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

The price is, of course, an important factor in any camera decision. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The D40X was somewhat cheaper (by 3 percent) than the D50 at launch, but both cameras fall into the same price category. 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 tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixel-units 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 tend to be more expensive and 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 D50 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.
In terms of underlying technology, both cameras are build around CCD sensors.
With 10MP, the D40X offers a higher resolution than the D50 (6MP), but the D40X has smaller individual pixels (pixel pitch of 6.11μm versus 7.85μm for the D50). However, the D40X is a somewhat more recent model (by 1 year and 10 months) than the D50, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels.
The resolution advantage of the Nikon D40X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D40X for good quality output (200 dots per inch) amounts to 19.4 x 13 inches or 49.2 x 32.9 cm, for very good quality (250 dpi) 15.5 x 10.4 inches or 39.3 x 26.3 cm, and for excellent quality (300 dpi) 12.9 x 8.6 inches or 32.8 x 21.9 cm. The corresponding values for the Nikon D50 are 15 x 10 inches or 38.2 x 25.4 cm for good quality, 12 x 8 inches or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inches or 25.5 x 16.9 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 D50 are ISO 200 to ISO 1600 (no boost).
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). Of the two cameras under review, the D40X has a notably higher overall DXO score than the D50 (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.5 bits higher color depth, 0.6 EV in additional dynamic range, and 0.1 stops of reduced 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.

Beyond body and sensor, cameras can and do differ across a range of features. The D40X and the D50 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 viewfinders of both cameras offer the same field of view (95%), but the viewfinder of the D40X has a higher magnification than the one of the D50 (0.53x vs 0.50x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Nikon D40X, the Nikon D50, and comparable cameras.
The D40X writes its imaging data to SDHC cards, while the D50 uses SD cards.
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 D50 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D40X and the D50 have been discontinued, but can regularly be found used on eBay. The D50 was replaced by the Nikon D40, while the D40X was followed by the Nikon D60 . 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? Is there a clear favorite between the Nikon D40X and the Nikon D50? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Nikon D40X:
- More detail: Offers more megapixels (10 vs 6MP) with a 29% higher linear resolution.
- Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (1.5 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (0.6 EV of extra DR).
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.53x vs 0.50x).
- Larger screen: Has a bigger rear LCD (2.5" vs 2.0") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (230k vs 130k dots).
- Faster burst: Shoots at higher frequency (3 vs 2.5 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (124x94mm vs 133x102mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 98g or 16 percent) and hence easier to carry around.
- Longer lasting: Can take more shots (520 versus 400) on a single battery charge.
- More modern: Is somewhat more recent (announced 1 year and 10 months after the D50).
Arguments in favor of the Nikon D50:
- More heavily discounted: Has been on the market for longer (launched in April 2005).
If the count of relative strengths (bullet points above) is taken as a measure, the D40X is the clear winner of the match-up (12 : 1 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains incomplete and does no justice, for example, to the way the D40X or the D50 perform in practice. 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 why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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 assessments were made in relation to similar cameras of the same technological generation. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
