Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D100 and the Nikon D5500? 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 D5500 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 D5500 can be obtained in two different colors (black, red), 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 D5500 is notably smaller (28 percent) than the Nikon D100. Moreover, the D5500 is substantially lighter (40 percent) than the D100. In this context, it is worth noting that neither the D100 nor the D5500 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.

Concerning battery life, the D100 gets 370 shots out of its Nikon EN-EL3 battery, while the D5500 can take 820 images on a single charge of its Nikon EN-EL14a power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D5500 was launched at a markedly lower price (by 55 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better isolate a subject from the 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 D5500 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.

Despite having a slightly smaller sensor, the D5500 offers a higher resolution of 24 megapixels, compared with 6 MP of the D100. 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 3.91μm versus 7.85μm for the D100). However, it should be noted that the D5500 is much more recent (by 12 years and 10 months) than the D100, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the D5500 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon D5500 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D5500 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 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 D5500 are ISO 100 to ISO 25600 (no boost).

In terms of underlying technology, the D100 is build around a CCD sensor, while the D5500 uses a CMOS imager. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The D5500 indeed provides for movie recording, while the D100 does not. The highest resolution format that the D5500 can use is 1080/60p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The D100 and the D5500 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 D5500 has a higher magnification than the one of the D100 (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 adjacent table lists some of the other core features of the Nikon D100 and Nikon D5500 along with similar information for a selection of comparators.

One feature that is present on the D100, but is missing on the D5500 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 D5500 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 D100 writes its imaging data to Compact Flash cards, while the D5500 uses SDXC 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 D5500 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D5500 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the D100 does not provide wifi capability.

Both the D100 and the D5500 have been discontinued, but can regularly be found used on ebay. The D100 was replaced by the Nikon D200, while the D5500 was followed by the Nikon D5600. Further information on the features and operation of the D100 and D5500 can be found, respectively, in the Nikon D100 Manual (free pdf) or the online Nikon D5500 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Nikon D100 and the Nikon D5500? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Nikon D100:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• 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).

Advantages of the Nikon D5500:

• More detail: Has more megapixels (24 vs 6MP), which boosts linear resolution by 100%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Broader imaging potential: Can capture not only stills but also 1080/60p video.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.57x vs 0.53x).
• Larger screen: Has a bigger rear LCD (3.2" vs 1.8") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (1037k vs 118k dots).
• More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (5 vs 3 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More compact: Is smaller (124x97mm vs 144x116mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 310g or 40 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (820 versus 370) out of a single battery charge.
• Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• More affordable: Was introduced into a lower priced category (55 percent cheaper at launch).
• More modern: Reflects 12 years and 10 months of technical progress since the D100 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the D5500 is the clear winner of the contest (18 : 3 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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 Nikon D100 and the Nikon D5500 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 D5500 perform in practice. 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.

Expert reviews

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], 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.

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

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.
