Sony A5100 vs Olympus E-PM2

The Sony Alpha A5100 and the Olympus PEN E-PM2 are two digital cameras that were revealed to the public, respectively, in August 2014 and September 2012. Both the A5100 and the E-PM2 are mirrorless interchangeable lens cameras that are based on an APS-C (A5100) and a Four Thirds (E-PM2) sensor. The Sony has a resolution of 24 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 Sony A5100 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 A5100 can be obtained in two different colors (black, white), while the E-PM2 is available in four color-versions (black, silver, red, white).

Size Sony A5100 vs Olympus E-PM2
Compare A5100 versus E-PM2 top
Comparison A5100 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 somewhat larger (2 percent) than the Sony A5100. However, the E-PM2 is markedly lighter (5 percent) than the A5100. In this context, it is worth noting that neither the A5100 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. 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 Sony E-Mount Lens Catalog (A5100) and the Micro Four Thirds Lens Catalog (E-PM2). 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 A5100 gets 400 shots out of its Sony NP-FW50 battery, while the E-PM2 can take 360 images on a single charge of its Olympus BLS-5 power pack. The power pack in the A5100 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

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

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 A5100 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.

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. 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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Sony A5100 features an APS-C sensor and the Olympus E-PM2 a Four Thirds sensor. The sensor area in the E-PM2 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 A5100 has a native 3:2 aspect ratio, while the one in the E-PM2 offers a 4:3 aspect.

Sony A5100 and Olympus E-PM2 sensor measures

With 24MP, the A5100 offers a higher resolution than the E-PM2 (15.9MP), but the A5100 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 3.76μm for the E-PM2) due to its larger sensor. Moreover, the A5100 is a somewhat more recent model (by 1 year and 11 months) than the E-PM2, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

The resolution advantage of the Sony A5100 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A5100 for good quality output (200 dots per inch) amounts to 30 x 20 inches or 76.2 x 50.8 cm, for very good quality (250 dpi) 24 x 16 inches or 61 x 40.6 cm, and for excellent quality (300 dpi) 20 x 13.3 inches or 50.8 x 33.9 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 A5100 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Sony Alpha A5100 has a native sensitivity range from ISO 100 to ISO 25600. The Olympus PEN E-PM2 offers exactly the same ISO settings.

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.

A5100 versus E-PM2 MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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. Of the two cameras under review, the A5100 has a notably higher overall DXO score than the E-PM2 (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.1 bits higher color depth, 0.5 EV in additional dynamic range, and 0.5 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The A5100 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 following table reports on some other key feature differences and similarities of the Sony A5100, the Olympus E-PM2, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The A5100 has one, while the E-PM2 does not. While the built-in flash of the A5100 is not very powerful, it can at times be useful as a fill-in light.

The A5100 has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the E-PM2 does not have a selfie-screen.

The A5100 writes its imaging data to SDXC or Memory Stick PRO Duo 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.

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 Sony Alpha A5100 and Olympus PEN E-PM2 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A5100 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 A5100 and the E-PM2 have been discontinued, but can regularly be found used on ebay. Neither of the two has a direct successor, so they represent the end of the respective camera lines from Sony and Olympus. Further information on the features and operation of the A5100 and E-PM2 can be found, respectively, in the Sony A5100 Manual (free pdf) or the online Olympus E-PM2 Manual.

Review summary

So what conclusions can be drawn? Which of the two cameras – the Sony A5100 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

Reasons to prefer the Sony Alpha A5100:

  • More detail: Offers more megapixels (24 vs 15.9MP) with a 25% higher linear resolution.
  • Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.1 bits more color depth).
  • Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
  • 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 (922k vs 460k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Longer lasting: Can take more shots (400 versus 360) on a single battery charge.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • 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.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More modern: Is somewhat more recent (announced 1 year and 11 months after the E-PM2).

ilogo

Arguments in favor of the Olympus PEN E-PM2:

  • More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
  • Faster burst: Shoots at higher frequency (8 vs 6 flaps/sec) to capture the decisive moment.
  • 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 count of individual advantages (bullet points above) is taken as a guide, the A5100 is the clear winner of the match-up (15 : 5 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding 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.

A5100 15:05 E-PM2

How about other alternatives? Do the specifications of the Sony A5100 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 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 A5100 or the E-PM2. 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 why expert reviews are important. 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 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 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.
