Olympus E-P5 vs Sony NEX-5
The Olympus PEN E-P5 and the Sony Alpha NEX-5 are two digital cameras that were officially introduced, respectively, in May 2013 and May 2010. Both the E-P5 and the NEX-5 are mirrorless interchangeable lens cameras that are based on a Four Thirds (E-P5) and an APS-C (NEX-5) sensor. The Olympus has a resolution of 15.9 megapixels, whereas the Sony provides 14 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 Olympus PEN E-P5 and the Sony Alpha NEX-5? 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.
The side-by-side display below illustrates the physical size and weight of the Olympus E-P5 and the Sony NEX-5. 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-P5 can be obtained in three different colors (black, silver, white), while the NEX-5 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 Sony NEX-5 is notably smaller (22 percent) than the Olympus E-P5. Moreover, the NEX-5 is markedly lighter (32 percent) than the E-P5. In this context, it is worth noting that neither the E-P5 nor the NEX-5 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 Sony E-Mount Lens Catalog (NEX-5). 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.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators.

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 NEX-5 was launched at a markedly lower price (by 30 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.
The size of the sensor inside a digital camera is one of the key determinants 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Olympus E-P5 features a Four Thirds sensor and the Sony NEX-5 an APS-C sensor. The sensor area in the NEX-5 is 62 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 NEX-5 offers a 3:2 aspect.
Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors.
Despite having a smaller sensor, the Olympus E-P5 offers a higher resolution of 15.9 megapixels, compared with 14 MP of the Sony NEX-5. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 3.76μm versus 5.11μm for the NEX-5). However, it should be noted that the E-P5 is much more recent (by 3 years) than the NEX-5, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently.
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 Sony Alpha NEX-5 are ISO 200 to ISO 12800 (no boost).
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 Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. 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 NEX-5 provides a faster frame rate than the E-P5. It can shoot movie footage at 1080/60i, while the Olympus is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The E-P5 and the NEX-5 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. However, optional viewfinders – the VF-4 for the E-P5 and the FDA-SV1 for the NEX-5 – are available as accessories. The adjacent table lists some of the other core features of the Olympus E-P5 and Sony NEX-5 along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The E-P5 has one, while the NEX-5 does not. While the built-in flash of the E-P5 is not very powerful, it can at times be useful as a fill-in light.The NEX-5 has an articulated screen that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in taking selfies. In contrast, the E-P5 does not have a selfie-screen.
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 NEX-5 uses SDXC or Memory Stick PRO Duo cards. The E-P5 supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the NEX-5 cannot take advantage of Ultra High Speed SD cards.
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 Sony Alpha NEX-5 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.
| WiFi |
|Olympus E-M10 II||Y||stereo||mono||-||-||micro||2.0||Y||-||-|
It is notable that the E-P5 offers wifi support, while the NEX-5 does not. Wifi can be a very convenient means to transfer image data to an off-camera location.
Both the E-P5 and the NEX-5 have been discontinued, but can regularly be found used on eBay. The NEX-5 was replaced by the Sony NEX-5N, while the E-P5 does not have a direct successor. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Olympus and Sony websites.
So what conclusions can be drawn? Is there a clear favorite between the Olympus E-P5 and the Sony NEX-5? Which camera is better? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Olympus PEN E-P5:
- 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 7 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.
- 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.
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More modern: Reflects 3 years of technical progress since the NEX-5 launch.
Arguments in favor of the Sony Alpha NEX-5:
- Better video: Provides higher movie framerates (1080/60i versus 1080/30p).
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- More compact: Is smaller (111x59mm vs 122x69mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 133g or 32 percent) and is thus easier to take along.
- More affordable: Was introduced into a lower priced category (30 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in May 2010).
If the number of relative strengths (bullet points above) is taken as a guide, the E-P5 is the clear winner of the match-up (10 : 6 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.

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the E-P5 or the NEX-5. 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.
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 (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). 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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
