Olympus E-M10 II versus Sony A6000
The Olympus OM-D E-M10 Mark II and the Sony Alpha A6000 are two digital cameras that were officially introduced, respectively, in August 2015 and February 2014. Both the E-M10 II and the A6000 are mirrorless interchangeable lens cameras that are based on a Four Thirds (E-M10 II) and an APS-C sensor. The Olympus has a resolution of 15.9 megapixel, whereas the Sony provides 24 MP.
The physical size and weight of the Olympus E-M10 II and the Sony A6000 are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth dimensions are rounded to the nearest millimeter. You can also use the toggle button to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left – the E-M10 II – represents the basis or 100 percent across all the size and weight measures).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A6000 is notably smaller (19 percent) than the Olympus E-M10 II. Moreover, the A6000 is markedly lighter (12 percent) than the E-M10 II. In this context, it is worth noting that neither the E-M10 II 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 find an overview of optics for the two cameras in the Micro Four Thirds Lens Catalog (E-M10 II) 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.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The A6000 was launched at a somewhat lower price (by 25 percent) than the E-M10 II, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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. 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 tent to lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Olympus E-M10 II 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-M10 II 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-M10 II (15.9MP), but the A6000 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 3.76μm for the E-M10 II) due to its larger sensor. However, the E-M10 II is a somewhat more recent model (by 1 year and 6 months) than the A6000, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the E-M10 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
For most cameras, data on sensor performance has been reported by DXO Mark. 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 has a markedly higher DXO score than the E-M10 II (overall score 9 points higher), which will translate into better image quality. The advantage is based on 1 bits higher color depth, 0.6 EV in additional dynamic range, and 0.7 stops in additional low light sensitivity. 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 are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/60p).
Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under consideration are similar with respect to both having an electronic viewfinder. However, the one in the E-M10 II offers a substantially higher resolution than the one in the A6000 (2360k vs 1440k dots). The following table reports on some other key feature differences and similarities of the Olympus E-M10 II, the Sony A6000, and comparable cameras.

Both the E-M10 II and the A6000 have been discontinued, but can regularly be found used on ebay. The A6000 was replaced by the Sony A6300, while the E-M10 II was followed by the Olympus E-M10 III.
So what is the bottom line? Is there a clear favorite between the Olympus E-M10 II and the Olympus E-M10 II? Below is a summary of the relative strengths of each of the two contestants.
Reasons to prefer the Olympus OM-D E-M10 Mark II:
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- More detailed viewfinder: Has higher resolution electronic viewfinder (2360k vs 1440k dots).
- More detailed LCD: Has a higher resolution rear screen (1040k vs 922k dots).
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Sharper images: Has hand-shake reducing image stabilization build-in.
- More modern: Is somewhat more recent (announced 1 year and 6 months after the A6000).
Arguments in favor of the Sony Alpha A6000:
- More detail: Has more megapixels (24 vs 15.9MP), which boosts linear resolution by 25%.
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better image quality: Scores markedly higher (9 points) in the DXO overall evaluation.
- More dynamic range: Captures a broader range of light and dark details (0.6 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (0.7 stops ISO advantage).
- Faster burst: Shoots at higher frequency (11 vs 8 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (120x67mm vs 120x83mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 46g or 12 percent) and is thus easier to take along.
- Longer lasting: Gets more shots (360 versus 320) out of a single battery charge.
- More affordable: Was released into a lower priced segment (25 percent cheaper at launch).
- More heavily discounted: Has been on the market for longer (launched in February 2014).
If the count of relative strengths (bullet points above) is taken as a measure, the A6000 is the clear winner of the contest (11 : 6 points). 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.
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 handling experience and imaging performance when actually working with the E-M10 II or the A6000. 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 table relays the overall verdicts of several of the most popular camera review sites. You can find the full text of the reviews, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted with care, though. The ratings are only valid when refering to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
If you would like to see a different side-by-side camera review, just use the search menu below. There is also a set of direct links to comparison reviews that other users of the CAM-parator app explored. If you do not see the camera that you are looking for, kindly get in touch, and I will try to add information on that model to the database.
