Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 400D and the Nikon D2Xs? 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.

Body comparison

An illustration of the physical size and weight of the Canon 400D and the Nikon D2Xs is provided in the side-by-side display below. 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 width, height and depth dimensions are rounded to the nearest millimeter.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D2Xs is considerably larger (122 percent) than the Canon 400D. Moreover, the D2Xs is substantially heavier (125 percent) than the 400D. It is noteworthy in this context that the D2Xs is splash and dust-proof, while the 400D 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. Yet, since both cameras are based around an APS-C sensor, their respective lenses will tend to have similar dimensions and heft. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (400D) and the Nikon Lens Catalog (D2Xs).

Concerning battery life, the 400D gets 370 shots out of its Canon NB-2LH battery, while the D2Xs can take 3800 images on a single charge of its Nikon EN-EL4a power pack. As can be seen in the images above, the D2Xs has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the 400D, Canon provides the BG-E3 vertical grip as an optional accessory (see here on ebay).

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 400D was launched at a markedly lower price (by 83 percent) than the D2Xs, 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.

Sensor comparison

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. 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 tend to be associated with larger, more expensive camera bodies and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the D2Xs is 13 percent bigger. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.6 (400D) and 1.5. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 12.2MP, the D2Xs offers a higher resolution than the 400D (10.1MP), but the D2Xs has smaller individual pixels (pixel pitch of 5.52μm versus 5.71μm for the 400D). It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation.

The resolution advantage of the Nikon D2Xs implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D2Xs for good quality output (200 dots per inch) amounts to 21.4 x 14.2 inches or 54.5 x 36.2 cm, for very good quality (250 dpi) 17.2 x 11.4 inches or 43.6 x 28.9 cm, and for excellent quality (300 dpi) 14.3 x 9.5 inches or 36.3 x 24.1 cm. The corresponding values for the Canon 400D are 19.4 x 13 inches or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inches or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inches or 32.9 x 21.9 cm for excellent quality prints.

The Canon EOS 400D has a native sensitivity range from ISO 100 to ISO 1600. The corresponding ISO settings for the Nikon D2Xs are ISO 100 to ISO 800, with the possibility to increase the ISO range to 800-3200.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The 400D and the D2Xs 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 D2Xs offers a wider field of view (100%) than the one in the 400D (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the D2Xs has a higher magnification (0.57x vs 0.49x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The adjacent table lists some of the other core features of the Canon 400D and Nikon D2Xs along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The 400D has one, while the D2Xs does not. While the built-in flash of the 400D is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the 400D and the D2Xs write their files to Compact Flash cards.

Connectivity comparison

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 Canon EOS 400D and Nikon D2Xs and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon D2Xs (unlike the 400D) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the 400D and the D2Xs have been discontinued, but can regularly be found used on ebay. The D2Xs was replaced by the Nikon D3X, while the 400D was followed by the Canon 450D. Further information on the features and operation of the 400D and D2Xs can be found, respectively, in the Canon 400D Manual (free pdf) or the online Nikon D2Xs Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Canon 400D or the Nikon D2Xs – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Advantages of the Canon EOS 400D:

• Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
• More compact: Is smaller (127x84mm vs 158x150mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 696g or 56 percent) and hence easier to carry around.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More affordable: Was introduced into a lower priced category (83 percent cheaper at launch).

Arguments in favor of the Nikon D2Xs:

• More detail: Has more megapixels (12.2 vs 10.1MP), which boosts linear resolution by 10%.
• 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 (0.57x vs 0.49x).
• Easier setting verification: Features a control panel on top to check shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
• More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
• Longer lasting: Gets more shots (3800 versus 370) out of a single battery charge.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.

If the number of relative strengths (bullet points above) is taken as a guide, the D2Xs is the clear winner of the contest (10 : 5 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 Canon 400D and the Nikon D2Xs 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 comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 400D or the D2Xs. 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.

Expert reviews

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], 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 above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
