Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D100 and the Nikon D40X? 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 D100 and the Nikon D40X 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 size dimensions are rounded to the nearest millimeter.
The D40X can be obtained in two different colors (black, silver), while the D100 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 D40X is considerably smaller (30 percent) than the Nikon D100. Moreover, the D40X is markedly lighter (33 percent) than the D100. In this context, it is worth noting that neither the D100 nor the D40X 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. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Any camera decision will naturally be influenced heavily by the price. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D40X was launched at a markedly lower price (by 64 percent) than the D100, 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.
The size of the imaging sensor is a crucial determinant 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 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 D40X 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.
In terms of underlying technology, both cameras are build around CCD sensors.
With 10MP, the D40X offers a higher resolution than the D100 (6MP), but the D40X has smaller individual pixels (pixel pitch of 6.11μm versus 7.85μm for the D100). Yet, the D40X is a much more recent model (by 5 years) 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 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 inch or 49.2 x 32.9 cm, for very good quality (250 dpi) 15.5 x 10.4 inch or 39.3 x 26.3 cm, and for excellent quality (300 dpi) 12.9 x 8.6 inch or 32.8 x 21.9 cm. The corresponding values for the Nikon D100 are 15 x 10 inch or 38.2 x 25.4 cm for good quality, 12 x 8 inch or 30.6 x 20.3 cm for very good quality, and 10 x 6.7 inch 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 D40X are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.
For many cameras, data on sensor performance has been reported by DXO Mark. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). 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 D100 and the D40X 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%), as well as the same magnification (0.53x). The table below summarizes some of the other core capabilities of the Nikon D100 and Nikon D40X in connection with corresponding information for a sample of similar cameras.

One feature that is present on the D100, 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 D100 writes its imaging data to Compact Flash cards, while the D40X uses SDHC 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 D100 and Nikon D40X and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D100 and the D40X have been discontinued, but can regularly be found used on eBay. The D100 was replaced by the Nikon D200, 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? Which of the two cameras – the Nikon D100 or the Nikon D40X – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Nikon D100:
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- More heavily discounted: Has been available for much longer (launched in February 2002).
Reasons to prefer the Nikon D40X:
- More detail: Has more megapixels (10 vs 6MP), which boosts linear resolution by 29%.
- 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 (230k vs 118k dots).
- More compact: Is smaller (124x94mm vs 144x116mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 258g or 33 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (520 versus 370) out of a single battery charge.
- Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
- More affordable: Was introduced into a lower priced category (64 percent cheaper at launch).
- More modern: Reflects 5 years of technical progress since the D100 launch.
If the number of relative strengths (bullet points above) is taken as a guide, the D40X is the clear winner of the contest (9 : 2 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 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 Nikon D100 and the Nikon D40X 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 says little about, for example, the shooting experience and imaging performance of the D100 and the D40X in practical situations. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.
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.

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. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
