Nikon 1 J4 vs Olympus E-PM2

The Nikon 1 J4 and the Olympus PEN E-PM2 are two digital cameras that were announced, respectively, in April 2014 and September 2012. Both the J4 and the E-PM2 are mirrorless interchangeable lens cameras that are based on an one-inch (J4) and a Four Thirds (E-PM2) sensor. The Nikon has a resolution of 18.2 megapixels, whereas the Olympus provides 15.9 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Body comparison

The side-by-side display below illustrates the physical size and weight of the Nikon 1 J4 and the Olympus E-PM2. 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 J4 can be obtained in four different colors (black, silver, orange, white), while the E-PM2 is also available in four color-versions, but different ones (black, silver, red, white).

Size Nikon 1 J4 vs Olympus E-PM2
Compare J4 versus E-PM2 top
Comparison J4 or E-PM2 rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-PM2 is notably larger (17 percent) than the Nikon 1 J4. Moreover, the E-PM2 is markedly heavier (16 percent) than the J4. In this context, it is worth noting that neither the J4 nor the E-PM2 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. If you want to switch the focus of the display and review another camera pair, you can move across to the CAM-parator tool and choose from the broad selection of possible camera comparisons there.

Note: Measurements and pricing do not include easily detachable parts, such as add-on or interchangeable lenses or optional viewfinders.

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 E-PM2 was somewhat cheaper (by 9 percent) than the J4 at launch, but both cameras fall into the same price category. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Nikon 1 J4 features an one-inch sensor and the Olympus E-PM2 a Four Thirds sensor. The sensor area in the E-PM2 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-PM2 offers a 4:3 aspect.

Nikon 1 J4 and Olympus E-PM2 sensor measures

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-PM2. 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-PM2). However, it should be noted that the J4 is a somewhat more recent model (by 1 year and 6 months) than the E-PM2, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage. Coming back to sensor resolution, it should be mentioned that the J4 has no anti-alias filter installed, so that it can capture all the detail its 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-PM2 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 PEN E-PM2 are ISO 100 to ISO 25600 (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.

J4 versus E-PM2 MP

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"). Of the two cameras under consideration, the E-PM2 offers substantially better image quality than the J4 (overall score 19 points higher). The advantage is based on 1.9 bits higher color depth, 1.5 EV in additional dynamic range, and 1.1 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

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 J4 provides a higher frame rate than the E-PM2. It can shoot video footage at 1080/60p, while the Olympus is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The J4 and the E-PM2 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-PM2 can be equipped with an optional viewfinder – the VF-4. The adjacent table lists some of the other core features of the Nikon 1 J4 and Olympus E-PM2 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 difference between the cameras concerns the presence of an on-board flash. The J4 has one, while the E-PM2 does not. While the built-in flash of the J4 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 J4 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 J4 writes its imaging data to micro SDXC cards, while the E-PM2 uses SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

It is notable that the J4 offers wifi support, while the E-PM2 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the J4 and the E-PM2 have been discontinued, but can regularly be found used on ebay. The J4 was replaced by the Nikon 1 J5, while the E-PM2 does not have a direct successor. Further information on the features and operation of the J4 and E-PM2 can be found, respectively, in the Nikon 1 J4 Manual (free pdf) or the online Olympus E-PM2 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Nikon 1 J4 or the Olympus E-PM2 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.

ilogo

Arguments in favor of the Nikon 1 J4:

  • More detail: Offers more megapixels (18.2 vs 15.9MP) with a 9% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • 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).
  • Faster burst: Shoots at higher frequency (60 vs 8 flaps/sec) to capture the decisive moment.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (100x60mm vs 110x64mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 37g or 14 percent) and hence easier to carry around.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • Easier file upload: Has wifi built in for automatic backup or image transfer to the web.
  • More modern: Is somewhat more recent (announced 1 year and 6 months after the E-PM2).

ilogo

Advantages of the Olympus PEN E-PM2:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Scores substantially higher (19 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.9 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.5 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1.1 stops ISO advantage).
  • More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
  • Longer lasting: Gets more shots (360 versus 300) 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.
  • More heavily discounted: Has been on the market for longer (launched in September 2012).

If the number of relative strengths (bullet points above) is taken as a guide, the J4 emerges as the winner of the contest (12 : 10 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision. 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.

J4 12:10 E-PM2

How about other alternatives? Do the specifications of the Nikon 1 J4 and the Olympus E-PM2 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the J4 and the E-PM2 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.

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. 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.
