Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus PEN E-PL2 and the Nikon 1 J5? 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 Olympus E-PL2 and the Nikon 1 J5 is provided 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 dimensions are rounded to the nearest millimeter.

The E-PL2 can be obtained in four different colors (black, silver, red, white), while the J5 is available in three color-versions (black, silver, white).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Nikon 1 J5 is notably smaller (28 percent) than the Olympus E-PL2. Moreover, the J5 is substantially lighter (36 percent) than the E-PL2. In this context, it is worth noting that neither the E-PL2 nor the J5 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 table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

The price is, of course, an important factor in any camera decision. 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 J5 was launched at a markedly lower price (by 33 percent) than the E-PL2, 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 sensor inside a digital camera is one of the key determinants 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 associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Olympus E-PL2 features a Four Thirds sensor and the Nikon 1 J5 an one-inch sensor. The sensor area in the J5 is 48 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 2.7. The sensor in the E-PL2 has a native 4:3 aspect ratio, while the one in the J5 offers a 3:2 aspect.

Despite having a smaller sensor, the J5 offers a higher resolution of 20.7 megapixels, compared with 12.2 MP of the E-PL2. 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 4.29μm for the E-PL2). However, it should be noted that the J5 is much more recent (by 4 years and 2 months) than the E-PL2, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. 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-PL2 are 20.2 x 15.1 inches or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inches or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inches or 34.1 x 25.6 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 Olympus PEN E-PL2 has a native sensitivity range from ISO 200 to ISO 6400. The corresponding ISO settings for the Nikon 1 J5 are ISO 160 to ISO 12800 (no boost).

In terms of underlying technology, the E-PL2 is build around a CMOS sensor, while the J5 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.

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"). Of the two cameras under consideration, the J5 has a markedly higher DXO score than the E-PL2 (overall score 10 points higher), which will translate into better image quality. The advantage is based on 0.3 bits lower color depth, 1.8 EV in additional dynamic range, and 0.3 stops of reduced low light sensitivity. 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 J5 provides a better video resolution than the E-PL2. It can shoot movie footage at 4K/15p, while the Olympus is limited to 720/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The E-PL2 and the J5 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. That said, the E-PL2 can be equipped with an optional viewfinder – the VF-2. The adjacent table lists some of the other core features of the Olympus E-PL2 and Nikon 1 J5 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-PL2 and the J5 is in-body image stabilization (IBIS). The E-PL2 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, the J5 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 Nikon 1 J5 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 E-PL2 writes its imaging data to SDHC cards, while the J5 uses SDXC cards. The J5 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the E-PL2 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 Olympus PEN E-PL2 and Nikon 1 J5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the E-PL2 has a hotshoe, while the J5 does not. This socket makes it possible to easily attach optional accessories, such as an external flash gun.

Both the E-PL2 and the J5 have been discontinued, but can regularly be found used on ebay. The E-PL2 was replaced by the Olympus E-PL3, while the J5 does not have a direct successor. Further information on the features and operation of the E-PL2 and J5 can be found, respectively, in the Olympus E-PL2 Manual (free pdf) or the online Nikon 1 J5 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Olympus E-PL2 or the Nikon 1 J5 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

Advantages of the Olympus PEN E-PL2:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
• Longer lasting: Can take more shots (280 versus 250) on a single battery charge.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• Better lighting: Features a hotshoe and can thus hold and trigger an external flash gun.
• More heavily discounted: Has been available for much longer (launched in January 2011).

Arguments in favor of the Nikon 1 J5:

• More detail: Has more megapixels (20.7 vs 12.2MP), which boosts linear resolution by 33%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Scores markedly higher (10 points) in the DXO overall evaluation.
• More dynamic range: Captures a broader range of light and dark details (1.8 EV of extra DR).
• Better video: Provides higher definition movie capture (4K/15p vs 720/30p).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• More detailed LCD: Has a higher resolution rear screen (1037k vs 460k dots).
• More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Faster burst: Shoots at higher frequency (60 vs 3 flaps/sec) to capture the decisive moment.
• 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 compact: Is smaller (98x60mm vs 114x72mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 131g or 36 percent) and is thus easier to take along.
• 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.
• Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
• More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
• More modern: Reflects 4 years and 2 months of technical progress since the E-PL2 launch.

If the number of relative strengths (bullet points above) is taken as a guide, the J5 is the clear winner of the contest (20 : 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 Olympus E-PL2 and the Nikon 1 J5 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-PL2 or the J5. 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 where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular 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 ratings are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
