Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon Coolpix L840 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 L840 and the Nikon P7800 are illustrated 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.

The L840 can be obtained in two different colors (black, red), while the P7800 is only available in black.

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon P7800 is notably larger (5 percent) than the Nikon L840. However, the P7800 is markedly lighter (26 percent) than the L840. In this context, it is worth noting that neither the L840 nor the P7800 are weather-sealed.

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

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 L840 was launched at a markedly lower price (by 46 percent) than the P7800, which puts it into a different market segment. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

Sensor comparison

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Nikon L840 features a 1/2.3-inch sensor and the Nikon P7800 a 1/1.7-inch sensor. The sensor area in the P7800 is 54 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 4.5. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Despite having a smaller sensor, the Nikon L840 offers a higher resolution of 15.9 megapixels, compared with 12 MP of the Nikon P7800. 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 1.33μm versus 1.89μm for the P7800). However, it should be noted that the L840 is a somewhat more recent model (by 1 year and 5 months) than the P7800, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage. Coming back to sensor resolution, it should be mentioned that the L840 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon L840 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the L840 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 cm. The corresponding values for the Nikon P7800 are 20 x 15 inches or 50.8 x 38.1 cm for good quality, 16 x 12 inches or 40.6 x 30.5 cm for very good quality, and 13.3 x 10 inches or 33.9 x 25.4 cm for excellent quality prints.

The Nikon Coolpix L840 has a native sensitivity range from ISO 100 to ISO 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 L840 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.

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. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the L840 provides a higher frame rate than the P7800. It can shoot video footage at 1080/60i, while the P7800 is limited to 1080/30p.

Feature comparison

Beyond 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 L840 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Nikon L840, the Nikon P7800, and comparable 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 L840 and the P7800 have zoom lenses built in. The L840 has a 22.5-855mm f/3.0-6.5 optic and the P7800 offers a 28-200mm f/2.0-4.0 (focal lengths in full frame equivalent terms). Hence, the L840 provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the P7800. The P7800 offers the faster maximum aperture.

Concerning the storage of imaging data, both the L840 and the P7800 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 L840 and Nikon Coolpix P7800 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the L840 offers wifi support, while the P7800 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the L840 and the P7800 have been discontinued, but can regularly be found used on ebay. The L840 was replaced by the Nikon B500, while the P7800 does not have a direct successor. Further information on the features and operation of the L840 and P7800 can be found, respectively, in the Nikon L840 Manual (free pdf) or the online Nikon P7800 Manual.

Review summary

So how do things add up? Which of the two cameras – the Nikon L840 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.

Reasons to prefer the Nikon Coolpix L840:

• More detail: Offers more megapixels (15.9 vs 12MP) with a 15% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• More tele-reach: Has a longer tele-lens for perspective compression and subject magnification.
• Longer lasting: Can take more shots (590 versus 350) on a single battery charge.
• Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced into a lower priced category (46 percent cheaper at launch).
• More modern: Is somewhat more recent (announced 1 year and 5 months after the P7800).

Arguments in favor of the Nikon Coolpix P7800:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• 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.
• 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.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Better light gathering: Has a lens with a wider maximum aperture (f/2.0 vs f/3.0).
• Less heavy: Has a lower weight (by 139g or 26 percent) and is thus easier to take along.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been on the market for longer (launched in September 2013).

If the number of relative strengths (bullet points above) is taken as a guide, the P7800 is the clear winner of the contest (14 : 10 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 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 L840 and the Nikon P7800 place the cameras among the top in their class? Find out in the latest Best Superzoom 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 says little about, for example, the shooting experience and imaging performance of the L840 and the P7800 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 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 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
