Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon 1 J4 and the Olympus OM-D E-M10 Mark III? 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 1 J4 and the Olympus E-M10 III 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 size dimensions are rounded to the nearest millimeter.

The J4 can be obtained in four different colors (black, silver, orange, white), while the E-M10 III is available in two color-versions (black, silver).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M10 III is considerably larger (71 percent) than the Nikon 1 J4. Moreover, the E-M10 III is substantially heavier (77 percent) than the J4. In this context, it is worth noting that neither the J4 nor the E-M10 III are weather-sealed.

The above size and weight comparisons are to some extent incomplete since they do not consider the interchangeable lenses that both of these cameras require. Hence, you might want to study and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

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 naturally be influenced heavily by the price. 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 J4 was launched at a somewhat lower price (by 15 percent) than the E-M10 III, which makes it more attractive for photographers on a tight budget. 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 sensor inside a digital camera is one of the key determinants 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Nikon 1 J4 features an one-inch sensor and the Olympus E-M10 III a Four Thirds sensor. The sensor area in the E-M10 III is 94 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.7 and 2.0. The sensor in the J4 has a native 3:2 aspect ratio, while the one in the E-M10 III offers a 4:3 aspect.

Despite having a smaller sensor, the Nikon 1 J4 offers a higher resolution of 18.2 megapixels, compared with 15.9 MP of the Olympus E-M10 III. 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 2.52μm versus 3.76μm for the E-M10 III). Moreover, it should be noted that the E-M10 III is much more recent (by 3 years and 4 months) than the J4, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.

The resolution advantage of the Nikon 1 J4 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the J4 for good quality output (200 dots per inch) amounts to 26.2 x 17.4 inches or 66.4 x 44.3 cm, for very good quality (250 dpi) 20.9 x 14 inches or 53.2 x 35.4 cm, and for excellent quality (300 dpi) 17.4 x 11.6 inches or 44.3 x 29.5 cm. The corresponding values for the Olympus E-M10 III are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.

The J4 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Nikon 1 J4 has a native sensitivity range from ISO 160 to ISO 12800. The corresponding ISO settings for the Olympus OM-D E-M10 Mark III 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 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the E-M10 III provides a better video resolution than the J4. It can shoot movie footage at 4K/30p, while the Nikon is limited to 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. For example, the E-M10 III has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the J4 relies on live view and the rear LCD for framing. The adjacent table lists some of the other core features of the Nikon 1 J4 and Olympus E-M10 III along with similar information for a selection of comparators.

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

One feature that differentiates the E-M10 III and the J4 is in-body image stabilization (IBIS). The E-M10 III reduces the risk of handshake-induced blur with all attached lenses, while the J4 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

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, both cameras under consideration feature an 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 III 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.

The J4 writes its imaging data to micro SDXC cards, while the E-M10 III uses SDXC cards. The E-M10 III supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the J4 can use UHS-I cards (up to 104 MB/s).

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 1 J4 and Olympus OM-D E-M10 Mark III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-M10 III has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The J4 does not feature such an accessory-socket.

Both the J4 and the E-M10 III have been discontinued, but can regularly be found used on ebay. The J4 was replaced by the Nikon 1 J5, while the E-M10 III was followed by the Olympus E-M10 IV. Further information on the features and operation of the J4 and E-M10 III can be found, respectively, in the Nikon 1 J4 Manual (free pdf) or the online Olympus E-M10 III Manual.

Review summary

So how do things add up? Which of the two cameras – the Nikon 1 J4 or the Olympus E-M10 III – 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.

Advantages of the Nikon 1 J4:

• More detail: Offers more megapixels (18.2 vs 15.9MP) with a 9% higher linear resolution.
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Faster burst: Shoots at higher frequency (60 vs 8.6 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (100x60mm vs 122x84mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 178g or 43 percent) and hence easier to carry around.
• More affordable: Was introduced into a lower priced segment (15 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in April 2014).

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

• 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 definition movie capture (4K/30p vs 1080/60p).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
• More modern: Reflects 3 years and 4 months of technical progress since the J4 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the E-M10 III is the clear winner of the contest (11 : 7 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 1 J4 and the Olympus E-M10 III place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera listing whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the J4 or the E-M10 III perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is where reviews by experts come in. 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 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
