Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D100 and the Nikon D2X? 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

The physical size and weight of the Nikon D100 and the Nikon D2X are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.

Size Nikon D100 vs Nikon D2X
Compare D100 versus D2X top
Comparison D100 or D2X rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D2X is notably larger (42 percent) than the Nikon D100. Moreover, the D2X is substantially heavier (61 percent) than the D100. It is noteworthy in this context that the D2X is splash and dust-proof, while the D100 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.

Concerning battery life, the D100 gets 370 shots out of its EN-EL3 battery, while the D2X can take 3800 images on a single charge of its EN-EL4a power pack. As can be seen in the images above, the D2X 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 D100, Nikon provides the MB-D100 vertical grip as an optional accessory (see here on eBay).

Any camera decision will obviously take relative prices into account. 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 D100 was launched at a markedly lower price (by 60 percent) than the D2X, which puts it into a different market segment. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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.

Sensor comparison

The size of the imaging sensor is a crucial determinant of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and 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 D2X is 1 percent bigger. 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.

Nikon D100 and Nikon D2X sensor measures

With 12.2MP, the D2X offers a higher resolution than the D100 (6MP), but the D2X has smaller individual pixels (pixel pitch of 5.52μm versus 7.85μm for the D100). Yet, the D2X is a much more recent model (by 2 years and 6 months) than the D100, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Nikon D2X implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D2X 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 Nikon D100 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 D100 has a native sensitivity range from ISO 200 to ISO 800, which can be extended to ISO 200-1600. The corresponding ISO settings for the Nikon D2X are ISO 100 to ISO 800, with the possibility to increase the ISO range to 100-3200.

D100 versus D2X MP

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"). The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Neither the D100 nor the D2X offer Live View, so that they cannot project the live image that the sensor receives onto the rear screen. Moreover, both cameras are still-image focused and cannot record videos.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The D100 and the D2X 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 D2X offers a wider field of view (100%) than the one in the D100 (95%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the D2X has a higher magnification (0.57x 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 D100 and Nikon D2X in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The D100 has one, while the D2X does not. While the built-in flash of the D100 is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the D100 and the D2X 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 Nikon D100 and Nikon D2X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon D2X (unlike the D100) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D100 and the D2X have been discontinued, but can regularly be found used on eBay. The D100 was replaced by the Nikon D200, while the D2X was followed by the Nikon D2Xs. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Nikon website.

Review summary

So what is the bottom line? Is there a clear favorite between the Nikon D100 and the Nikon D2X? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.


Advantages of the Nikon D100:

  • More compact: Is smaller (144x116mm vs 158x150mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 472g or 38 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 (60 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in February 2002).


Reasons to prefer the Nikon D2X:

  • More detail: Has more megapixels (12.2 vs 6MP), which boosts linear resolution by 43%.
  • 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 0.53x).
  • Larger screen: Has a bigger rear LCD (2.5" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (235k vs 118k dots).
  • 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.
  • Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • More modern: Reflects 2 years and 6 months of technical progress since the D100 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the D2X is the clear winner of the contest (13 : 5 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

D100 05:13 D2X

How about other alternatives? Do the specifications of the Nikon D100 and the Nikon D2X 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 D100 or the D2X 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.

Expert reviews

This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

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, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
