Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon 1 J5 and the Olympus PEN E-PL10? 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 J5 and the Olympus E-PL10 are illustrated 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 J5 can be obtained in three different colors (black, silver, white), while the E-PL10 is available in four color-versions (black, brown, blue, white).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-PL10 is notably larger (35 percent) than the Nikon 1 J5. Moreover, the E-PL10 is substantially heavier (65 percent) than the J5. In this context, it is worth noting that neither the J5 nor the E-PL10 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

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 J5 was launched at a markedly lower price (by 33 percent) than the E-PL10, 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.

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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its 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 J5 features an one-inch sensor and the Olympus E-PL10 a Four Thirds sensor. The sensor area in the E-PL10 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 J5 has a native 3:2 aspect ratio, while the one in the E-PL10 offers a 4:3 aspect.

Despite having a smaller sensor, the Nikon 1 J5 offers a higher resolution of 20.7 megapixels, compared with 15.9 MP of the Olympus E-PL10. 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 2.37μm versus 3.76μm for the E-PL10). Moreover, it should be noted that the E-PL10 is much more recent (by 4 years and 6 months) than the J5, 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 J5 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Nikon 1 J5 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the J5 for good quality output (200 dots per inch) amounts to 27.8 x 18.6 inches or 70.7 x 47.1 cm, for very good quality (250 dpi) 22.3 x 14.8 inches or 56.6 x 37.7 cm, and for excellent quality (300 dpi) 18.6 x 12.4 inches or 47.1 x 31.4 cm. The corresponding values for the Olympus E-PL10 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 J5 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Nikon 1 J5 has a native sensitivity range from ISO 160 to ISO 12800. The corresponding ISO settings for the Olympus PEN E-PL10 are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-25600.

In terms of underlying technology, the J5 is build around a BSI-CMOS sensor, while the E-PL10 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.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the E-PL10 provides a faster frame rate than the J5. It can shoot movie footage at 4K/30p, while the Nikon is limited to 4K/15p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The J5 and the E-PL10 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 table below summarizes some of the other core capabilities of the Nikon 1 J5 and Olympus E-PL10 in connection with corresponding information for a sample of similar cameras.

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

One feature that differentiates the E-PL10 and the J5 is in-body image stabilization (IBIS). The E-PL10 reduces the risk of handshake-induced blur with all attached lenses, while the J5 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 Nikon 1 J5 and the Olympus E-PL10 both have 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 J5 and the E-PL10 write their files to SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of 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 J5 and Olympus PEN E-PL10 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-PL10 has a hotshoe, which makes it possible to easily attach optional accessories, such as an external flash gun. The J5 does not feature such an accessory-socket.

Both the J5 and the E-PL10 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 Olympus. Further information on the features and operation of the J5 and E-PL10 can be found, respectively, in the Nikon 1 J5 Manual (free pdf) or the online Olympus E-PL10 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Nikon 1 J5 and the Olympus E-PL10? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Nikon 1 J5:

• More detail: Offers more megapixels (20.7 vs 15.9MP) with a 16% higher linear resolution.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• 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 (98x60mm vs 117x68mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 149g or 39 percent) and hence easier to carry around.
• Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
• More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in April 2015).

Reasons to prefer the Olympus PEN E-PL10:

• 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 (4K/30p versus 4K/15p).
• Longer lasting: Gets more shots (350 versus 250) out of a single battery charge.
• 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.
• Easier wireless transfer: Supports Bluetooth for image sharing without cables.
• More modern: Reflects 4 years and 6 months of technical progress since the J5 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the E-PL10 emerges as the winner of the match-up (11 : 9 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 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 1 J5 and the Olympus E-PL10 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 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 J5 and the E-PL10 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 where reviews by experts come in. 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 assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price 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.
