Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus PEN E-P5 and the Fujifilm X-A1? 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-P5 and the Fujifilm X-A1. 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 measures are rounded to the nearest millimeter.

The E-P5 can be obtained in three different colors (black, silver, white), while the X-A1 is available in two color-versions (black, blue).

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Fujifilm X-A1 is notably smaller (7 percent) than the Olympus E-P5. Moreover, the X-A1 is markedly lighter (21 percent) than the E-P5. In this context, it is worth noting that neither the E-P5 nor the X-A1 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-P5) and the Fujinon X Lens Catalog (X-A1). 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-P5 gets 330 shots out of its Olympus BLN-1 battery, while the X-A1 can take 350 images on a single charge of its Fujifilm NP-W126 power pack.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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.

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The X-A1 was launched at a markedly lower price (by 60 percent) than the E-P5, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels in a sensor of the same technological generation. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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-P5 features a Four Thirds sensor and the Fujifilm X-A1 an APS-C sensor. The sensor area in the X-A1 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-P5 has a native 4:3 aspect ratio, while the one in the X-A1 offers a 3:2 aspect.

With 16MP, the X-A1 offers a higher resolution than the E-P5 (15.9MP), but the X-A1 nevertheless has larger individual pixels (pixel pitch of 4.80μm versus 3.76μm for the E-P5) due to its larger sensor. Moreover, the X-A1 is a somewhat more recent model (by 4 months) than the E-P5, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.

The Olympus PEN E-P5 has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 100-25600. The corresponding ISO settings for the Fujifilm X-A1 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. 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 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, and both provide the same movie specifications (1080/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a range of features. The E-P5 and the X-A1 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-P5 can be equipped with an optional viewfinder – the VF-4. The table below summarizes some of the other core capabilities of the Olympus E-P5 and Fujifilm X-A1 in connection with corresponding information for a sample of similar cameras.

One feature that differentiates the E-P5 and the X-A1 is in-body image stabilization (IBIS). The E-P5 reduces the risk of handshake-induced blur with all attached lenses, while the X-A1 offers no blur reduction with lenses that themselves do not provide optical image stabilization.

The Olympus E-P5 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-P5 writes its imaging data to SDXC cards, while the X-A1 uses SDHC 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-P5 and Fujifilm X-A1 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Both the E-P5 and the X-A1 have been discontinued, but can regularly be found used on ebay. The E-P5 was replaced by the Olympus E-P7, while the X-A1 was followed by the Fujifilm X-A2. Further information on the features and operation of the E-P5 and X-A1 can be found, respectively, in the Olympus E-P5 Manual (free pdf) or the online Fujifilm X-A1 Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Olympus E-P5 or the Fujifilm X-A1 – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Advantages of the Olympus PEN E-P5:

• More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
• More detailed LCD: Has a higher resolution rear screen (1037k vs 920k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
• Faster burst: Shoots at higher frequency (9 vs 5.6 flaps/sec) to capture the decisive moment.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• Sharper images: Has hand-shake reducing image stabilization built-in.
• More heavily discounted: Has been on the market for longer (launched in May 2013).

Reasons to prefer the Fujifilm X-A1:

• 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.
• More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
• Less heavy: Has a lower weight (by 90g or 21 percent) and is thus easier to take along.
• More affordable: Was introduced into a lower priced category (60 percent cheaper at launch).
• More modern: Was introduced somewhat (4 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (8 points each). 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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-P5 and the Fujifilm X-A1 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 incomplete and does no justice, for example, to the way the E-P5 or the X-A1 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

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.

Note: (+ +) highly recommended; (+) recommended; (o) reviewed; (..) not available.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
