Olympus E-M10 IV vs Sony A6000
The Olympus OM-D E-M10 Mark IV and the Sony Alpha A6000 are two digital cameras that were revealed to the public, respectively, in August 2020 and February 2014. Both the E-M10 IV and the A6000 are mirrorless interchangeable lens cameras that are based on a Four Thirds (E-M10 IV) and an APS-C (A6000) sensor. The Olympus has a resolution of 20.2 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 OM-D E-M10 Mark IV 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.
An illustration of the physical size and weight of the Olympus E-M10 IV and the Sony A6000 is provided in the side-by-side display below. 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 size dimensions are rounded to the nearest millimeter.
The E-M10 IV can be obtained in two different colors (black, silver), while the A6000 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 Sony A6000 is notably smaller (22 percent) than the Olympus E-M10 IV. Moreover, the A6000 is markedly lighter (10 percent) than the E-M10 IV. In this context, it is worth noting that neither the E-M10 IV 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-M10 IV) 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 battery packs of both cameras can be charged via USB, 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. 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 listed launch 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 14 percent) than the E-M10 IV, which makes it more attractive for photographers on a tight budget. 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.
The size of the sensor inside a digital camera is one of the key determinants 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Of the two cameras under consideration, the Olympus E-M10 IV 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 IV has a native 4:3 aspect ratio, while the one in the A6000 offers a 3:2 aspect.
In terms of underlying technology, both cameras are build around CMOS sensors.
With 24MP, the A6000 offers a higher resolution than the E-M10 IV (20.2MP), but the A6000 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 3.34μm for the E-M10 IV) due to its larger sensor. However, the E-M10 IV is a much more recent model (by 6 years and 5 months) than the A6000, and its sensor will 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 IV has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
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-M10 IV are 25.9 x 19.4 inches or 65.8 x 49.4 cm for good quality, 20.7 x 15.6 inches or 52.7 x 39.5 cm for very good quality, and 17.3 x 13 inches or 43.9 x 32.9 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 OM-D E-M10 Mark IV 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 A6000 are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 100-51200.
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. 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 also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the E-M10 IV provides a higher video resolution than the A6000. It can shoot video footage at 4K/30p, while the Sony is limited to 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 IV offers a substantially higher resolution than the one in the A6000 (2360k vs 1440k dots). The adjacent table lists some of the other core features of the Olympus E-M10 IV and Sony A6000 along with similar information for a selection of comparators.

One feature that differentiates the E-M10 IV and the A6000 is in-body image stabilization (IBIS). The E-M10 IV 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-M10 IV 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 A6000 does not have a selfie-screen.
The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the E-M10 IV is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).
The Olympus E-M10 IV 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-M10 IV writes its imaging data to SDXC cards, while the A6000 uses SDXC or Memory Stick PRO Duo cards. The E-M10 IV supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the A6000 can use UHS-I cards (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 OM-D E-M10 Mark IV and Sony Alpha A6000 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

The E-M10 IV is a recent model that features in the current product line-up of Olympus. In contrast, the A6000 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the A6000 was succeeded 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 what is the bottom line? Is the Olympus E-M10 IV better than the Sony A6000 or vice versa? A synthesis of the relative strong points of each of the models is listed below.

If the count of individual advantages (bullet points above) is taken as a guide, the E-M10 IV is the clear winner of the match-up (13 : 8 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-M10 IV 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the E-M10 IV or the A6000 perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.
This is why hands-on reviews by experts are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (amateurphotographer [AP], cameralabs [CL], 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.

Care should be taken when interpreting the review scores above, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
