Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus PEN E-PM2 and the Fujifilm X-E1? 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 Olympus E-PM2 and the Fujifilm X-E1. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter.

The E-PM2 can be obtained in four different colors (black, silver, red, white), while the X-E1 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 Fujifilm X-E1 is notably larger (37 percent) than the Olympus E-PM2. Moreover, the X-E1 is markedly heavier (30 percent) than the E-PM2. In this context, it is worth noting that neither the E-PM2 nor the X-E1 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can compare the optics available for the two cameras in the Micro Four Thirds Lens Catalog (E-PM2) and the Fujinon X Lens Catalog (X-E1). Mirrorless cameras, such as the two under consideration, have the additional advantage of having a short flange to focal plane distance, which makes it possible to mount many lenses from other systems onto the camera via adapters.

Concerning battery life, the E-PM2 gets 360 shots out of its Olympus BLS-5 battery, while the X-E1 can take 350 images on a single charge of its Fujifilm NP-W126 power pack.

The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 E-PM2 was launched at a markedly lower price (by 50 percent) than the X-E1, 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 imaging sensor is a crucial determinant 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Olympus E-PM2 features a Four Thirds sensor and the Fujifilm X-E1 an APS-C sensor. The sensor area in the X-E1 is 64 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.5. The sensor in the E-PM2 has a native 4:3 aspect ratio, while the one in the X-E1 offers a 3:2 aspect.

With 16MP, the X-E1 offers a higher resolution than the E-PM2 (15.9MP), but the X-E1 nevertheless has larger individual pixels (pixel pitch of 4.80μm versus 3.76μm for the E-PM2) due to its larger sensor. It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. Coming back to sensor resolution, it should be mentioned that the X-E1 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The Olympus PEN E-PM2 has a native sensitivity range from ISO 100 to ISO 25600. The corresponding ISO settings for the Fujifilm X-E1 are ISO 200 to ISO 6400, with the possibility to increase the ISO range to 100-25600.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Like most digital cameras, the E-PM2 uses a Bayer filter for capturing RGB colors on a square grid of photosensors. In contrast, the X-E1 employs a more randomized X-Trans layout of photosites, which according to Fujifilm helps to minimize moiré.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar 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-PM2 provides a higher frame rate than the X-E1. It can shoot video footage at 1080/30p, while the Fujifilm is limited to 1080/24p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the X-E1 has an electronic viewfinder (2360k dots), which can be very helpful when shooting in bright sunlight. In contrast, the E-PM2 relies on live view and the rear LCD for framing. 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 Olympus E-PM2 and Fujifilm X-E1 along with similar information for a selection of comparators.

One feature that differentiates the E-PM2 and the X-E1 is in-body image stabilization (IBIS). The E-PM2 reduces the risk of handshake-induced blur with all attached lenses, while the X-E1 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

Concerning the storage of imaging data, both the E-PM2 and the X-E1 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 Olympus PEN E-PM2 and Fujifilm X-E1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X-E1 has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The E-PM2 does not feature such a mic input.

Both the E-PM2 and the X-E1 have been discontinued, but can regularly be found used on ebay. The X-E1 was replaced by the Fujifilm X-E2, while the E-PM2 does not have a direct successor. Further information on the features and operation of the E-PM2 and X-E1 can be found, respectively, in the Olympus E-PM2 Manual (free pdf) or the online Fujifilm X-E1 Manual.

Review summary

So how do things add up? Is there a clear favorite between the Olympus E-PM2 and the Fujifilm X-E1? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

Arguments in favor of the Olympus PEN E-PM2:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• Better video: Provides higher movie framerates (1080/30p versus 1080/24p).
• Larger screen: Has a bigger rear LCD (3.0" vs 2.8") for image review and settings control.
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster burst: Shoots at higher frequency (8 vs 6 flaps/sec) to capture the decisive moment.
• More compact: Is smaller (110x64mm vs 129x75mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 81g or 23 percent) and hence easier to carry around.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More affordable: Was introduced into a lower priced category (50 percent cheaper at launch).

Advantages of the Fujifilm X-E1:

• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
• Richer colors: The pixel size advantage translates into images with better, more accurate colors.
• More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
• Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
• Better sound: Can connect to an external microphone for higher quality sound recording.
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.

If the count of individual advantages (bullet points above) is taken as a guide, the E-PM2 comes out slightly ahead of the X-E1 (9 : 8 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 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-PM2 and the Fujifilm X-E1 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 remains incomplete and does no justice, for example, to the way the E-PM2 or the X-E1 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.

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.
