Sony A5100 vs Olympus E-P2
The Sony Alpha A5100 and the Olympus PEN E-P2 are two digital cameras that were officially introduced, respectively, in August 2014 and November 2009. Both the A5100 and the E-P2 are mirrorless interchangeable lens cameras that are based on an APS-C (A5100) and a Four Thirds (E-P2) sensor. The Sony has a resolution of 24 megapixels, whereas the Olympus provides 12.2 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.
Going beyond this snapshot of core features and characteristics, what are the differences between the Sony Alpha A5100 and the Olympus PEN E-P2? 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 physical size and weight of the Sony A5100 and the Olympus E-P2 are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter.
The A5100 can be obtained in two different colors (black, white), while the E-P2 is available in three color-versions (black, silver, white).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-P2 is notably larger (22 percent) than the Sony A5100. Moreover, the E-P2 is markedly heavier (25 percent) than the A5100. In this context, it is worth noting that neither the A5100 nor the E-P2 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-P2). 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-P2 can take 300 images on a single charge of its Olympus BLS-1 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 table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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.

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 A5100 was launched at a markedly lower price (by 31 percent) than the E-P2, which puts it into a different market segment. 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 size of the imaging sensor is a crucial determinant 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 Sony A5100 features an APS-C sensor and the Olympus E-P2 a Four Thirds sensor. The sensor area in the E-P2 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-P2 offers a 4:3 aspect.
With 24MP, the A5100 offers a higher resolution than the E-P2 (12.2MP), but the A5100 has smaller individual pixels (pixel pitch of 3.91μm versus 4.29μm for the E-P2). However, the A5100 is a much more recent model (by 4 years and 9 months) than the E-P2, and its sensor will have benefitted from technological advances during this time that 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-P2 are 20.2 x 15.1 inches or 51.2 x 38.4 cm for good quality, 16.1 x 12.1 inches or 41 x 30.7 cm for very good quality, and 13.4 x 10.1 inches or 34.1 x 25.6 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 corresponding ISO settings for the Olympus PEN E-P2 are ISO 100 to ISO 6400 (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.
For many cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under review, the A5100 provides substantially higher image quality than the E-P2, with an overall score that is 24 points higher. This advantage is based on 2.3 bits higher color depth, 2.3 EV in additional dynamic range, and 1.4 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A5100 provides a higher video resolution than the E-P2. It can shoot video footage at 1080/60p, while the Olympus is limited to 720/30p.
Feature comparison
Apart from body and sensor, cameras can and do differ across a variety of features. The A5100 and the E-P2 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-P2 can be equipped with an optional viewfinder – the VF-2. The following table reports on some other key feature differences and similarities of the Sony A5100, the Olympus E-P2, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The A5100 has one, while the E-P2 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-P2 does not have a selfie-screen.The A5100 writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the E-P2 uses SDHC cards. The A5100 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the E-P2 cannot take advantage of Ultra High Speed SD cards.
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-P2 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-P2 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the A5100 and the E-P2 have been discontinued, but can regularly be found used on ebay. The E-P2 was replaced by the Olympus E-P3, while the A5100 does not have a direct successor. Further information on the features and operation of the A5100 and E-P2 can be found, respectively, in the Sony A5100 Manual (free pdf) or the online Olympus E-P2 Manual.
Review summary
So how do things add up? Which of the two cameras – the Sony A5100 or the Olympus E-P2 – has the upper hand? Is one clearly better than the other? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Sony Alpha A5100:
- More detail: Offers more megapixels (24 vs 12.2MP) with a 43% higher linear resolution.
- Better image quality: Scores substantially higher (24 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (2.3 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (2.3 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (1.4 stops ISO advantage).
- Better video: Provides higher definition movie capture (1080/60p vs 720/30p).
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- More detailed LCD: Has a higher resolution rear screen (922k vs 230k dots).
- More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (6 vs 3 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (110x63mm vs 121x70mm) and thus needs less room in the bag.
- Less heavy: Is lighter (by 72g or 20 percent) and hence easier to carry around.
- Longer lasting: Can take more shots (400 versus 300) 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.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More affordable: Was introduced into a lower priced category (31 percent cheaper at launch).
- More modern: Reflects 4 years and 9 months of technical progress since the E-P2 launch.
Arguments in favor of the Olympus PEN E-P2:
- More framing options: Can be equipped with a hotshoe-mounted accessory-viewfinder.
- 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 around for much longer (launched in November 2009).
If the count of relative strengths (bullet points above) is taken as a measure, the A5100 is the clear winner of the match-up (22 : 4 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.
How about other alternatives? Do the specifications of the Sony A5100 and the Olympus E-P2 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 says little about, for example, the shooting experience and imaging performance of the A5100 and the E-P2 in practical situations. 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 where reviews by experts come in. 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 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.
