Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D100 and the Nikon D7000? 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 D7000 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 dimensions are rounded to the nearest millimeter.

Compare D100 versus D7000 top
Comparison D100 or D7000 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon D7000 is notably smaller (17 percent) than the Nikon D100. In terms of weight, the two cameras are very close. It is noteworthy in this context that the D7000 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 D7000 can take 1050 images on a single charge of its EN-EL15 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

Notes: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The D7000 was launched at a somewhat lower price (by 25 percent) than the D100, which makes it more attractive for photographers on a tight budget. 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.

Sensor comparison

The size of the sensor inside a digital camera is one of the key determinants 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. 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 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. 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 D7000 sensor measures

With 16.1MP, the D7000 offers a higher resolution than the D100 (6MP), but the D7000 has smaller individual pixels (pixel pitch of 4.80μm versus 7.85μm for the D100). Yet, the D7000 is a much more recent model (by 8 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 D7000 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D7000 for good quality output (200 dots per inch) amounts to 24.6 x 16.3 inches or 62.6 x 41.5 cm, for very good quality (250 dpi) 19.7 x 13.1 inches or 50.1 x 33.2 cm, and for excellent quality (300 dpi) 16.4 x 10.9 inches or 41.7 x 27.6 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 D7000 are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 100-25600.

Note: DXO values in italics represent estimates based on sensor size and age.

Many modern cameras cannot only take still pictures, but also record videos. The D7000 indeed provides for movie recording, while the D100 does not. The highest resolution format that the D7000 can use is 1080/24p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The D100 and the D7000 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 D7000 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 D7000 has a higher magnification (0.63x 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 D7000 along with similar information for a selection of comparators.

The Nikon D7000 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 D7000 uses SDXC cards. The D7000 features dual card slots, which can be very useful in case a memory card fails. In contrast, the D100 only has one slot.

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 D7000 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D100 and the D7000 have been discontinued, but can regularly be found used on eBay. The D100 was replaced by the Nikon D200, while the D7000 was followed by the Nikon D7100. 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 the Nikon D100 better than the Nikon D7000 or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Nikon D100:

  • More heavily discounted: Has been available for much longer (launched in February 2002).


Arguments in favor of the Nikon D7000:

  • More detail: Has more megapixels (16.1 vs 6MP), which boosts linear resolution by 64%.
  • Broader imaging potential: Can capture not only stills but also 1080/24p video.
  • 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 (0.63x vs 0.53x).
  • Larger screen: Has a bigger rear LCD (3.0" vs 1.8") for image review and settings control.
  • More detailed LCD: Has a higher resolution rear screen (921k vs 118k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Faster burst: Shoots at higher frequency (6 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 (132x105mm vs 144x116mm) and will fit more readily into a bag.
  • Longer lasting: Gets more shots (1050 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).
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • More affordable: Was released into a lower priced segment (25 percent cheaper at launch).
  • More modern: Reflects 8 years and 6 months of technical progress since the D100 launch.

If the count of individual advantages (bullet points above) is taken as a guide, the D7000 is the clear winner of the contest (16 : 1 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.

D100 01:16 D7000

How about other alternatives? Do the specifications of the Nikon D100 and the Nikon D7000 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 says little about, for example, the shooting experience and imaging performance of the D100 and the D7000 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.

Expert reviews

This is why hands-on reviews by experts are important. 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.

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

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
