Nikon D100 vs P7800
The Nikon D100 and the Nikon Coolpix P7800 are two digital cameras that were revealed to the public, respectively, in February 2002 and September 2013. The D100 is a DSLR, while the P7800 is a fixed lens compact. The cameras are based on an APS-C (D100) and a 1/1.7-inch (P7800) sensor. The D100 has a resolution of 6 megapixels, whereas the P7800 provides 12 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D100 and the Nikon Coolpix P7800? 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 side-by-side display below illustrates the physical size and weight of the Nikon D100 and the Nikon P7800. 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon P7800 is considerably smaller (44 percent) than the Nikon D100. In this context, it is worth noting that neither the D100 nor the P7800 are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the P7800 has a lens built in, whereas the D100 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the D100 and their specifications in the Nikon Lens Catalog.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

Any camera decision will obviously take relative prices into account. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The P7800 was launched at a lower price than the D100, despite having a lens built in. 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 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. 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 associated with larger, more expensive camera bodies and lenses.
Of the two cameras under consideration, the Nikon D100 features an APS-C sensor and the Nikon P7800 a 1/1.7-inch sensor. The sensor area in the P7800 is 88 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 4.5. The sensor in the D100 has a native 3:2 aspect ratio, while the one in the P7800 offers a 4:3 aspect.
Despite having a smaller sensor, the P7800 offers a higher resolution of 12 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 1.89μm versus 7.85μm for the D100). However, it should be noted that the P7800 is much more recent (by 11 years and 6 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.
The resolution advantage of the Nikon P7800 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the P7800 for good quality output (200 dots per inch) amounts to 20 x 15 inches or 50.8 x 38.1 cm, for very good quality (250 dpi) 16 x 12 inches or 40.6 x 30.5 cm, and for excellent quality (300 dpi) 13.3 x 10 inches or 33.9 x 25.4 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 Coolpix P7800 are ISO 80 to ISO 3200, with the possibility to increase the ISO range to 80-6400.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. The P7800 indeed provides for movie recording, while the D100 does not. The highest resolution format that the P7800 can use is 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the P7800 has an electronic viewfinder (921k dots), while the D100 has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The adjacent table lists some of the other core features of the Nikon D100 and Nikon P7800 along with similar information for a selection of comparators.

One feature that is present on the D100, but is missing on the P7800 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 P7800 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the D100 does not have a selfie-screen.
The Nikon P7800 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 P7800 uses SDXC 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 Coolpix P7800 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the D100 and the P7800 have been discontinued, but can regularly be found used on eBay. The D100 was replaced by the Nikon D200, while the P7800 does not have a direct successor. 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 is the bottom line? Which of the two cameras – the Nikon D100 or the Nikon P7800 – has the upper hand? Is one clearly better than the other? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Nikon D100:
- Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
- Richer colors: The pixel size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
- Brighter framing: Features an optical viewfinder for clear, lag-free composition.
- Easier setting verification: Features an LCD display on top to control shooting parameters.
- More flexible: Can take a variety of interchangeable lenses, including specialty optics.
- More heavily discounted: Has been available for much longer (launched in February 2002).
Arguments in favor of the Nikon Coolpix P7800:
- More detail: Has more megapixels (12 vs 6MP), which boosts linear resolution by 38%.
- Broader imaging potential: Can capture not only stills but also 1080/30p video.
- More framing info: Has an electronic viewfinder that displays shooting data.
- 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).
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (8 vs 3 flaps/sec) to capture the decisive moment.
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Ready to shoot: Comes with an integrated lens, while the D100 requires a separate lens.
- More compact: Is smaller (119x78mm vs 144x116mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight even though it has a lens built in (unlike the D100).
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- Faster data transfer: Supports a more advanced USB protocol (2.0 vs 1.1).
- More affordable: Was introduced at a lower price, despite coming with a built-in lens.
- More modern: Reflects 11 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 P7800 is the clear winner of the contest (16 : 8 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 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 P7800 place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Travel-Zoom Camera listings whether the two cameras rank among the cream of the crop.
In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the D100 or the P7800. 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 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.

The review scores listed above should be treated with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
