Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D100 and the Nikon D80? 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 side-by-side display below illustrates the physical size and weight of the Nikon D100 and the Nikon D80. 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.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D80 is notably smaller (19 percent) than the Nikon D100. Moreover, the D80 is markedly lighter (14 percent) than the D100. In this context, it is worth noting that neither the D100 nor the D80 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 D80 can take 600 images on a single charge of its Nikon EN-EL3e power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

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 D80 was launched at a markedly lower price (by 50 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.

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. 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 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 D80 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.

With 10MP, the D80 offers a higher resolution than the D100 (6MP), but the D80 has smaller individual pixels (pixel pitch of 6.11μm versus 7.85μm for the D100). Yet, the D80 is a much more recent model (by 4 years and 5 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 D80 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D80 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 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 D80 are ISO 100 to ISO 1600, with the possibility to increase the ISO range to 100-3200.

Technology-wise, both cameras are equipped with CCD (Charged Coupled Device) 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.

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.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The D100 and the D80 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 D80 has a higher magnification than the one of the D100 (0.62x 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 D80 in connection with corresponding information for a sample of similar cameras.

One feature that is present on the D100, but is missing on the D80 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 D80 uses SDHC 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 D80 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D100 and the D80 have been discontinued, but can regularly be found used on ebay. The D100 was replaced by the Nikon D200, while the D80 was followed by the Nikon D90. Further information on the features and operation of the D100 and D80 can be found, respectively, in the Nikon D100 Manual (free pdf) or the online Nikon D80 Manual.

Review summary

So what is the bottom line? Is there a clear favorite between the Nikon D100 and the Nikon D80? Which camera is better? 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 D80:

• More detail: Has more megapixels (10 vs 6MP), which boosts linear resolution by 29%.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.62x 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 (230k vs 118k dots).
• More compact: Is smaller (132x103mm vs 144x116mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 112g or 14 percent) and is thus easier to take along.
• Longer lasting: Gets more shots (600 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 (50 percent cheaper at launch).
• More modern: Reflects 4 years and 5 months of technical progress since the D100 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the D80 is the clear winner of the contest (10 : 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 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.

How about other alternatives? Do the specifications of the Nikon D100 and the Nikon D80 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 D80 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 (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.

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 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.
