Going beyond this snapshot of core features and characteristics, what are the differences between the Fujifilm X-A2 and the Olympus OM-D E-M5? 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 Fujifilm X-A2 and the Olympus E-M5. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth dimensions are rounded to the nearest millimeter.

The X-A2 can be obtained in three different colors (black, brown, white), while the E-M5 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-M5 is notably larger (39 percent) than the Fujifilm X-A2. Moreover, the E-M5 is markedly heavier (21 percent) than the X-A2. It is noteworthy in this context that the E-M5 is splash and dust-proof, while the X-A2 does not feature any corresponding weather-sealing.

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 Fujinon X Lens Catalog (X-A2) and the Micro Four Thirds Lens Catalog (E-M5). 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 X-A2 gets 410 shots out of its Fujifilm NP-W126 battery, while the E-M5 can take 360 images on a single charge of its Olympus BLN-1 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 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 X-A2 was launched at a markedly lower price (by 69 percent) than the E-M5, 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 imaging sensor is a crucial determinant 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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Fujifilm X-A2 features an APS-C sensor and the Olympus E-M5 a Four Thirds sensor. The sensor area in the E-M5 is 39 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 2.0. The sensor in the X-A2 has a native 3:2 aspect ratio, while the one in the E-M5 offers a 4:3 aspect.

With 16MP, the X-A2 offers a slightly higher resolution than the E-M5 (15.9MP), but the X-A2 nevertheless has larger individual pixels (pixel pitch of 4.80μm versus 3.76μm for the E-M5) due to its larger sensor. Moreover, the X-A2 is a much more recent model (by 2 years and 11 months) than the E-M5, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The Fujifilm X-A2 has a native sensitivity range from ISO 200 to ISO 6400, which can be extended to ISO 100-25600. The corresponding ISO settings for the Olympus OM-D E-M5 are ISO 200 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.

Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service determines an overall sensor rating, as well as sub-scores for low-light sensitivity ("DXO Sports"), dynamic range ("DXO Landscape"), and color depth ("DXO Portrait"). 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 can also record movies. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the E-M5 provides a faster frame rate than the X-A2. It can shoot movie footage at 1080/60i, while the Fujifilm is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. For example, the E-M5 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the X-A2 relies on live view and the rear LCD for framing. The following table reports on some other key feature differences and similarities of the Fujifilm X-A2, the Olympus E-M5, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The X-A2 has one, while the E-M5 does not. While the built-in flash of the X-A2 is not very powerful, it can at times be useful as a fill-in light.

Concerning the storage of imaging data, both the X-A2 and the E-M5 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 Fujifilm X-A2 and Olympus OM-D E-M5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the X-A2 offers wifi support, while the E-M5 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.

Both the X-A2 and the E-M5 have been discontinued, but can regularly be found used on ebay. The E-M5 was replaced by the Olympus E-M5 II, while the X-A2 was followed by the Fujifilm X-A3. Further information on the features and operation of the X-A2 and E-M5 can be found, respectively, in the Fujifilm X-A2 Manual (free pdf) or the online Olympus E-M5 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Fujifilm X-A2 or the Olympus E-M5 – 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.

Reasons to prefer the Fujifilm X-A2:

• Better image quality: Features a larger and more technologically advanced imaging 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.
• More detailed LCD: Has a higher resolution rear screen (920k vs 610k dots).
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• More compact: Is smaller (117x67mm vs 122x89mm) and thus needs less room in the bag.
• Less heavy: Is lighter (by 75g or 18 percent) and hence easier to carry around.
• Longer lasting: Can take more shots (410 versus 360) on a single battery charge.
• 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 affordable: Was introduced into a lower priced category (69 percent cheaper at launch).
• More modern: Reflects 2 years and 11 months of technical progress since the E-M5 launch.

Arguments in favor of the Olympus OM-D E-M5:

• Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
• Easier framing: Has an electronic viewfinder for image composition and settings control.
• Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
• Faster burst: Shoots at higher frequency (9 vs 5.6 flaps/sec) to capture the decisive moment.
• Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
• Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
• More heavily discounted: Has been around for much longer (launched in February 2012).

If the number of relative strengths (bullet points above) is taken as a guide, the X-A2 is the clear winner of the match-up (13 : 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 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 Fujifilm X-A2 and the Olympus E-M5 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 remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the X-A2 or the E-M5. 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 expert reviews 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.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
