Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D300S 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.

Body comparison

The physical size and weight of the Nikon D300S and the Nikon P7800 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 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 P7800 is considerably smaller (45 percent) than the Nikon D300S. It is worth mentioning in this context that the D300S is splash and dust resistant, while the P7800 does not feature any corresponding weather-sealing.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the P7800 has a lens built in, whereas the D300S 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 D300S and their specifications in the Nikon Lens Catalog.

Concerning battery life, the D300S gets 950 shots out of its Nikon EN-EL3e battery, while the P7800 can take 350 images on a single charge of its Nikon EN-EL14 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. 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 naturally be influenced heavily by the price. 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 D300S, despite having a lens built in. 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 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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.

Of the two cameras under consideration, the Nikon D300S 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 D300S has a native 3:2 aspect ratio, while the one in the P7800 offers a 4:3 aspect.

With 12.2MP, the D300S offers a slightly higher resolution than the P7800 (12MP), but the D300S nevertheless has larger individual pixels (pixel pitch of 5.53μm versus 1.89μm for the P7800) due to its larger sensor. However, the P7800 is a much more recent model (by 4 years and 1 month) than the D300S, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The Nikon D300S has a native sensitivity range from ISO 200 to ISO 3200, which can be extended to ISO 100-6400. 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.

In terms of underlying technology, the D300S is build around a CMOS sensor, while the P7800 uses a BSI-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"). Of the two cameras under review, the D300S provides substantially higher image quality than the P7800, with an overall score that is 16 points higher. This advantage is based on 1.3 bits higher color depth, 0.5 EV in additional dynamic range, and 2 stops in additional low light sensitivity. 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 also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the P7800 provides a better video resolution than the D300S. It can shoot movie footage at 1080/30p, while the D300S is limited to 720/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the P7800 has an electronic viewfinder (921k dots), while the D300S 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 following table reports on some other key feature differences and similarities of the Nikon D300S, the Nikon P7800, and comparable cameras.

One feature that is present on the D300S, 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 Nikon D300S and the Nikon P7800 both have 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 D300S writes its imaging data to Compact Flash or SDXC cards, while the P7800 uses SDXC cards. The D300S features dual card slots, which can be very useful in case a memory card fails. In contrast, the P7800 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 D300S and Nikon Coolpix P7800 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Nikon D300S (unlike the P7800) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

Both the D300S and the P7800 have been discontinued, but can regularly be found used on ebay. The D300S was replaced by the Nikon D500, while the P7800 does not have a direct successor. Further information on the features and operation of the D300S and P7800 can be found, respectively, in the Nikon D300S Manual (free pdf) or the online Nikon P7800 Manual.

Review summary

So what is the bottom line? Is the Nikon D300S better than the Nikon P7800 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Nikon D300S:

• Better image quality: Scores substantially higher (16 points) in the DXO overall assessment.
• Richer colors: Generates images with noticeably better colors (1.3 bits more color depth).
• Better low-light sensitivity: Requires less light for good images (2 stops ISO advantage).
• Brighter framing: Features an optical viewfinder for clear, lag-free composition.
• Easier setting verification: Features an LCD display on top to control shooting parameters.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• More flexible: Can take a variety of interchangeable lenses, including specialty optics.
• Longer lasting: Can take more shots (950 versus 350) on a single battery charge.
• Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
• Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
• Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
• More heavily discounted: Has been available for much longer (launched in July 2009).

Reasons to prefer the Nikon Coolpix P7800:

• Better video: Provides higher definition movie capture (1080/30p vs 720/24p).
• More framing info: Has an electronic viewfinder that displays shooting data.
• 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 7 flaps/sec) to capture the decisive moment.
• Ready to shoot: Comes with an integrated lens, while the D300S requires a separate lens.
• More compact: Is smaller (119x78mm vs 147x115mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight even though it has a lens built in (unlike the D300S).
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More modern: Reflects 4 years and 1 month of technical progress since the D300S launch.

If the number of relative strengths (bullet points above) is taken as a guide, the D300S comes out slightly ahead of the P7800 (12 : 11 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 wildlife photographer will view the differences between cameras in a way that diverges from the perspective of a family photog, and a person interested in architecture has distinct needs from a sports 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 D300S 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 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 D300S or the P7800 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 expert reviews 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.

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

The review scores listed above should be treated with care, 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, please note that some of the review sites have changed their methodology and reporting over time.
