Olympus E-P3 vs Sony A6000
The Olympus PEN E-P3 and the Sony Alpha A6000 are two digital cameras that were revealed to the public, respectively, in June 2011 and February 2014. Both the E-P3 and the A6000 are mirrorless interchangeable lens cameras that are based on a Four Thirds (E-P3) and an APS-C (A6000) sensor. The Olympus has a resolution of 12.2 megapixels, whereas the Sony provides 24 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-P3 and the Sony Alpha A6000? 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 physical size and weight of the Olympus E-P3 and the Sony A6000 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.
Both cameras are available in three different colors (black, silver, white).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A6000 is somewhat smaller (4 percent) than the Olympus E-P3. Moreover, the A6000 is markedly lighter (7 percent) than the E-P3. In this context, it is worth noting that neither the E-P3 nor the A6000 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-P3) and the Sony E-Mount Lens Catalog (A6000). 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-P3 gets 330 shots out of its BLS-5 battery, while the A6000 can take 360 images on a single charge of its NP-FW50 power pack. The power pack in the A6000 can be charged via the USB port, which can be very convenient when travelling.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table.

Any camera decision will naturally be influenced heavily by the price. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The A6000 was launched at a somewhat lower price (by 25 percent) than the E-P3, which makes it more attractive for photographers on a tight budget. 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 generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels 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 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-P3 features a Four Thirds sensor and the Sony A6000 an APS-C sensor. The sensor area in the A6000 is 63 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-P3 has a native 4:3 aspect ratio, while the one in the A6000 offers a 3:2 aspect.
With 24MP, the A6000 offers a higher resolution than the E-P3 (12.2MP), but the A6000 has smaller individual pixels (pixel pitch of 3.91μm versus 4.29μm for the E-P3). Yet, the A6000 is a much more recent model (by 2 years and 7 months) than the E-P3, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.
The resolution advantage of the Sony A6000 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A6000 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-P3 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 A6000 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Olympus PEN E-P3 has a native sensitivity range from ISO 200 to ISO 12800. The corresponding ISO settings for the Sony Alpha A6000 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.
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. Of the two cameras under consideration, the A6000 offers substantially better image quality than the E-P3 (overall score 31 points higher). The advantage is based on 3.3 bits higher color depth, 3 EV in additional dynamic range, and 1.3 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.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the A6000 provides a faster frame rate than the E-P3. It can shoot movie footage at 1080/60p, while the Olympus is limited to 1080/60i.
Beyond body and sensor, cameras can and do differ across a range of features. For example, the A6000 has an electronic viewfinder (1440k dots), which can be very helpful when shooting in bright sunlight. In contrast, the E-P3 relies on live view and the rear LCD for framing. That said, the E-P3 can be equipped with an optional viewfinder – the VF-3. The table below summarizes some of the other core capabilities of the Olympus E-P3 and Sony A6000 in connection with corresponding information for a sample of similar cameras.
One feature that differentiates the E-P3 and the A6000 is in-body image stabilization (IBIS). The E-P3 reduces the risk of handshake-induced blur with all attached lenses, while the A6000 offers no blur reduction with lenses that themselves do not provide optical image stabilization.
The E-P3 writes its imaging data to SDXC cards, while the A6000 uses SDXC or Memory Stick PRO Duo cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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-P3 and Sony Alpha A6000 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.
| WiFi |
It is notable that the A6000 offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the E-P3 does not provide wifi capability.
Both the E-P3 and the A6000 have been discontinued, but can regularly be found used on eBay. The E-P3 was replaced by the Olympus E-P5, while the A6000 was followed by the Sony A6300. 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 how do things add up? Is there a clear favorite between the Olympus E-P3 and the Sony A6000? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Olympus PEN E-P3:
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- More heavily discounted: Has been available for much longer (launched in June 2011).
Reasons to prefer the Sony Alpha A6000:

If the count of relative strengths (bullet points above) is taken as a measure, the A6000 is the clear winner of the contest (15 : 3 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 Olympus E-P3 and the Sony A6000 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 E-P3 and the A6000 in practical situations. 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 following table reports the overall ratings of the cameras as published by some of the major 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 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, please note that some of the review sites have changed their methodology and reporting over time.
