Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon Coolpix P7800 and the Pentax MX-1? 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

An illustration of the physical size and weight of the Nikon P7800 and the Pentax MX-1 is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side 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 Pentax MX-1 is notably smaller (20 percent) than the Nikon P7800. Moreover, the MX-1 is slightly lighter (2 percent) than the P7800. In this context, it is worth noting that neither the P7800 nor the MX-1 are weather-sealed.

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 retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The MX-1 was somewhat cheaper (by 9 percent) than the P7800 at launch, but both cameras fall into the same price category. 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. 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 a 1/1.7-inch sensor and have a format factor (sometimes also referred to as "crop factor") of 4.5. Within the spectrum of camera sensors, this places the review cameras among the smaller-sensor digicams that favor affordability and compact design. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

The two cameras under review do not only share the same sensor size, but also offer an identical resolution of 12 megapixels. This similarity in sensor specs implies that both the P7800 and the MX-1 have the same pixel density, as well as the same pixel size. It should, however, be noted that the P7800 is a somewhat more recent model (by 7 months) than the MX-1, and its sensor might have benefitted from technological advances during this time.

The Nikon Coolpix P7800 has a native sensitivity range from ISO 80 to ISO 3200, which can be extended to ISO 80-6400. The corresponding ISO settings for the Pentax MX-1 are ISO 100 to ISO 12800 (no boost).

In terms of underlying technology, the P7800 is build around a BSI-CMOS sensor, while the MX-1 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.

For many cameras, data on sensor performance has been reported by DXO Mark. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under review, the P7800 has a notably higher overall DXO score than the MX-1 (overall score 5 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.8 bits higher color depth, 0.4 EV in additional dynamic range, and 0.1 stops of reduced low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the P7800 has an electronic viewfinder (921k dots), which can be very helpful when shooting in bright sunlight. In contrast, the MX-1 relies on live view and the rear LCD for framing. The table below summarizes some of the other core capabilities of the Nikon P7800 and Pentax MX-1 in connection with corresponding information for a sample of similar cameras.

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.

Both the P7800 and the MX-1 have zoom lenses built in. The P7800 has a 28-200mm f/2.0-4.0 optic and the MX-1 offers a 28-112mm f/1.8-2.5 (focal lengths in full frame equivalent terms). Hence, the Nikon and Pentax provide the same view at the wide-angle end, but the Pentax has less tele-photo reach at the long end. The MX-1 offers the faster maximum aperture.

Concerning the storage of imaging data, both the P7800 and the MX-1 write their files to 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 Coolpix P7800 and Pentax MX-1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the P7800 has a hotshoe, while the MX-1 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the P7800 and the MX-1 have been discontinued, but can regularly be found used on ebay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Nikon and Pentax. Further information on the features and operation of the P7800 and MX-1 can be found, respectively, in the Nikon P7800 Manual (free pdf) or the online Pentax MX-1 Manual.

Review summary

So what conclusions can be drawn? Is the Nikon P7800 better than the Pentax MX-1 or vice versa? The listing below highlights the relative strengths of the two models.

Advantages of the Nikon Coolpix P7800:

• Better image quality: Scores markedly higher (5 points) in the DXO overall assessment.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• 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 1 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Longer lasting: Can take more shots (350 versus 290) on a single battery charge.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More modern: Is somewhat more recent (announced 7 months after the MX-1).

Reasons to prefer the Pentax MX-1:

• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Better light gathering: Has a lens with a wider maximum aperture (f/1.8 vs f/2.0).
• More compact: Is smaller (122x61mm vs 119x78mm) and will fit more readily into a bag.
• More heavily discounted: Has been on the market for longer (launched in January 2013).

If the number of relative strengths (bullet points above) is taken as a guide, the P7800 is the clear winner of the match-up (11 : 4 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 P7800 and the Pentax MX-1 place the cameras among the top in their class? Find out in the latest Best Travel-Zoom Camera listing 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 incomplete and does no justice, for example, to the way the P7800 or the MX-1 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.

The above review scores should be interpreted with care, though. The ratings are only valid when referring to cameras in the same category and of the same age. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
