Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon Coolpix L840 and the Sony Cyber-shot DSC-RX0? 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 L840 and the Sony RX0 is provided 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.

The L840 can be obtained in two different colors (black, red), while the RX0 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 Sony RX0 is considerably smaller (73 percent) than the Nikon L840. Moreover, the RX0 is substantially lighter (80 percent) than the L840. It is noteworthy in this context that the RX0 is splash and dust-proof, while the L840 does not feature any corresponding weather-sealing. More than that, the RX0 is water-proof up to 10m and can, thus, be used for underwater photography.

The power pack in the RX0 can be charged via the USB port, which can be very convenient when travelling.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives. In case you want to display and compare another camera duo, you can use the CAM-parator app to select your camera combination among a large number of options.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The L840 was launched at a markedly lower price (by 57 percent) than the RX0, 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 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. 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 L840 features a 1/2.3-inch sensor and the Sony RX0 an one-inch sensor. The sensor area in the RX0 is 314 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 2.7. The sensor in the L840 has a native 4:3 aspect ratio, while the one in the RX0 offers a 3:2 aspect.

Despite having a smaller sensor, the Nikon L840 offers a higher resolution of 15.9 megapixels, compared with 15.4 MP of the Sony RX0. 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 2.74μm for the RX0). Moreover, it should be noted that the RX0 is much more recent (by 2 years and 6 months) than the L840, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. 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 Nikon Coolpix L840 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Sony Cyber-shot DSC-RX0 are ISO 125 to ISO 12800 (no boost).

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. 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"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the RX0 provides a faster frame rate than the L840. It can shoot movie footage at 1080/60p, while the Nikon is limited to 1080/60i.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The L840 and the RX0 are similar in the sense that neither of the two has a viewfinder. The images are, thus, framed using live view on the rear LCD. The following table reports on some other key feature differences and similarities of the Nikon L840, the Sony RX0, and comparable cameras.

Note: *) Information refers to the mechanical shutter, unless the camera only has an electronic one.

One difference between the cameras concerns the presence of an on-board flash. The L840 has one, while the RX0 does not. While the built-in flash of the L840 is not very powerful, it can at times be useful as a fill-in light.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the RX0 only has electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The L840 is equipped with a zoom lens, while the RX0 comes with a built-in prime. The L840 has a 22.5-855mm f/3.0-6.5 optic and the RX0 offers a 24mm f/4.0 (focal lengths in full frame equivalent terms). Hence, the Nikon provides a wider angle of view at the short end, as well as more tele-photo reach at the long end than the Sony. The L840 offers the faster maximum aperture.

The L840 writes its imaging data to SDXC cards, while the RX0 uses micro SDXC or Memory Stick Micro cards. The RX0 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the L840 cannot take advantage of Ultra High Speed SD 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 Sony Cyber-shot DSC-RX0 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX0 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The L840 does not feature such a mic input.

Both the L840 and the RX0 have been discontinued, but can regularly be found used on ebay. The L840 was replaced by the Nikon B500, while the RX0 was followed by the Sony RX0 II. Further information on the features and operation of the L840 and RX0 can be found, respectively, in the Nikon L840 Manual (free pdf) or the online Sony RX0 Manual.

Review summary

So how do things add up? Is the Nikon L840 better than the Sony RX0 or vice versa? Below is a summary of the relative strengths of each of the two contestants.

Arguments in favor of the Nikon Coolpix L840:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Larger screen: Has a bigger rear LCD (3.0" vs 1.5") for image review and settings control.
• More detailed LCD: Has a higher resolution rear screen (921k vs 230k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Faster burst: Shoots at higher frequency (7.4 vs 5.5 flaps/sec) to capture the decisive moment.
• Better light gathering: Has a lens with a wider maximum aperture (f/3.0 vs f/4.0).
• Wider view: Has a wider-angle lens that facilitates landscape or interior shots.
• Longer lasting: Can take more shots (590 versus 240) on a single battery charge.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced into a lower priced category (57 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in February 2015).

Reasons to prefer the Sony Cyber-shot DSC-RX0:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better image quality: Is equipped with a larger and more technologically advanced sensor.
• Richer colors: The sensor size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger sensor captures a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger sensor produces good images even in poorly lit environments.
• Better video: Provides higher movie framerates (1080/60p versus 1080/60i).
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• More compact: Is smaller (59x41mm vs 113x78mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 428g or 80 percent) and is thus easier to take along.
• Easier travel charging: Can be conveniently charged via its USB port.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Water-proof: Is rugged and sealed and can thus be used for underwater photography (up to 10m).
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Reflects 2 years and 6 months of technical progress since the L840 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the RX0 emerges as the winner of the match-up (16 : 13 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 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 Sony RX0 place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Prime Lens Compact 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 says little about, for example, the shooting experience and imaging performance of the L840 and the RX0 in practical situations. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable.

Expert reviews

This is why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 above review scores should be interpreted 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
