Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon Coolpix L840 and the Olympus OM-D E-M10 Mark II? 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 side-by-side display below illustrates the physical size and weight of the Nikon L840 and the Olympus E-M10 II. 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 E-M10 II is available in three color-versions (black, silver, brown).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M10 II is notably larger (13 percent) than the Nikon L840. In this context, it is worth noting that neither the L840 nor the E-M10 II are weather-sealed.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the L840 has a lens built in, whereas the E-M10 II 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 E-M10 II and their specifications in the Micro Four Thirds Lens Catalog.

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 L840 was launched at a lower price than the E-M10 II, 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 generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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 Olympus E-M10 II a Four Thirds sensor. The sensor area in the E-M10 II is 704 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 5.6 and 2.0. Both cameras feature a native aspect ratio (sensor width to sensor height) of 4:3.

Even though the E-M10 II has a larger sensor, both cameras offer the same resolution of 15.9 megapixels. This implies that the E-M10 II has a lower pixel density and larger individual pixels (with a pixel pitch of 3.76μm versus 1.33μm for the L840), which gives it a potential advantage in terms of light gathering capacity. In addition, the E-M10 II is a somewhat more recent model (by 6 months) than the L840, and its sensor might have benefitted from technological advances during this time. Coming back to sensor resolution, it should be mentioned that neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The Nikon Coolpix L840 has a native sensitivity range from ISO 100 to ISO 6400. The corresponding ISO settings for the Olympus OM-D E-M10 Mark II are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.

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.

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 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the E-M10 II 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 variety of features. For example, the E-M10 II has an electronic viewfinder (2360k 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 Olympus E-M10 II, and comparable cameras.

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

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The E-M10 II has a touchscreen, while the L840 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 E-M10 II is one of those camera that have an additional 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 Olympus E-M10 II 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.

Concerning the storage of imaging data, both the L840 and the E-M10 II write their files to SDXC cards. The E-M10 II 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 Olympus OM-D E-M10 Mark II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-M10 II has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The L840 does not feature such an accessory-socket.

Both the L840 and the E-M10 II have been discontinued, but can regularly be found used on ebay. The L840 was replaced by the Nikon B500, while the E-M10 II was followed by the Olympus E-M10 III. Further information on the features and operation of the L840 and E-M10 II can be found, respectively, in the Nikon L840 Manual (free pdf) or the online Olympus E-M10 II Manual.

Review summary

So how do things add up? Is the Nikon L840 better than the Olympus E-M10 II or vice versa? The listing below highlights the relative strengths of the two models.

Reasons to prefer the Nikon Coolpix L840:

• Ready to shoot: Has a lens built-in, whereas the E-M10 II requires a separate lens.
• More compact: Is smaller (113x78mm vs 120x83mm) and thus needs less room in the bag.
• Longer lasting: Can take more shots (590 versus 320) on a single battery charge.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced at a lower price, despite coming with a built-in lens.
• More heavily discounted: Has been on the market for longer (launched in February 2015).

Arguments in favor of the Olympus OM-D E-M10 Mark II:

• 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).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Less disturbing: Has an electronic shutter option for completely silent shooting.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More modern: Was introduced somewhat (6 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the E-M10 II is the clear winner of the contest (14 : 6 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 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 L840 and the Olympus E-M10 II place the cameras among the top in their class? Find out in the latest Best Superzoom Camera and Best Mirrorless Interchangeable Lens 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 L840 or the E-M10 II perform in practice. 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.

Care should be taken when interpreting the review scores above, 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 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.
