Sony A6400 vs Olympus E-M10 II
The Sony Alpha A6400 and the Olympus OM-D E-M10 Mark II are two digital cameras that were officially introduced, respectively, in January 2019 and August 2015. Both the A6400 and the E-M10 II are mirrorless interchangeable lens cameras that are based on an APS-C (A6400) and a Four Thirds (E-M10 II) sensor. The Sony has a resolution of 24 megapixels, whereas the Olympus provides 15.9 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 A6400 and the Olympus OM-D E-M10 Mark II? 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
An illustration of the physical size and weight of the Sony A6400 and the Olympus E-M10 II is provided in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All size dimensions are rounded to the nearest millimeter.
The E-M10 II can be obtained in three different colors (black, silver, brown), while the A6400 is only available in black.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M10 II is notably larger (24 percent) than the Sony A6400. However, the E-M10 II is slightly lighter (3 percent) than the A6400. It is worth mentioning in this context that the A6400 is splash and dust resistant, while the E-M10 II does not feature any corresponding weather-sealing.
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 (A6400) and the Micro Four Thirds Lens Catalog (E-M10 II). 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 A6400 gets 410 shots out of its Sony NP-FW50 battery, while the E-M10 II can take 320 images on a single charge of its Olympus BLS-50 power pack. The power pack in the A6400 can be charged via the USB port, so that it is not always necessary to take the battery charger along when travelling.

The price is, of course, an important factor in any camera decision. 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 E-M10 II was launched at a markedly lower price (by 28 percent) than the A6400, 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
Sensor comparison
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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to isolate a subject from the 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 Sony A6400 features an APS-C sensor and the Olympus E-M10 II a Four Thirds sensor. The sensor area in the E-M10 II 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 A6400 has a native 3:2 aspect ratio, while the one in the E-M10 II offers a 4:3 aspect.
With 24MP, the A6400 offers a higher resolution than the E-M10 II (15.9MP), but the A6400 nevertheless has larger individual pixels (pixel pitch of 3.91μm versus 3.76μm for the E-M10 II) due to its larger sensor. Moreover, the A6400 is a much more recent model (by 3 years and 4 months) than the E-M10 II, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels. 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.
The resolution advantage of the Sony A6400 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A6400 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 II are 23 x 17.3 inches or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inches or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inches or 39 x 29.3 cm for excellent quality prints.
The A6400 has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Sony Alpha A6400 has a native sensitivity range from ISO 100 to ISO 32000, which can be extended to ISO 100-102400. The corresponding ISO settings for the Olympus OM-D E-M10 Mark II are ISO 200 to ISO 25600, with the possibility to increase the ISO range to 100-25600.
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.
Consistent information on actual sensor performance is available from DXO Mark for many cameras. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the A6400 has a notably higher overall DXO score than the E-M10 II (overall score 10 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.9 bits higher color depth, 1.1 EV in additional dynamic range, and 0.8 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 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 A6400 provides a higher video resolution than the E-M10 II. It can shoot video footage at 4K/30p, while the Olympus is limited to 1080/60p.
Feature comparison
Beyond body and sensor, cameras can and do differ across a range of features. The two cameras under review are similar with respect to both having an electronic viewfinder. However, the one in the E-M10 II offers a slightly higher resolution than the one in the A6400 (2360k vs 2359k dots).

One feature that differentiates the E-M10 II and the A6400 is in-body image stabilization (IBIS). The E-M10 II reduces the risk of handshake-induced blur with all attached lenses, while the A6400 offers no blur reduction with lenses that themselves do not provide optical image stabilization.
The A6400 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-M10 II 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, both cameras under consideration feature an 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 II 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 A6400 writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the E-M10 II uses SDXC cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 A6400 and Olympus OM-D E-M10 Mark II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A6400 has a microphone port, which is missing on the E-M10 II. Such an external microphone input can help to substantially improve the quality of audio recordings when a good external microphone is used.
The A6400 is a recent model that features in the current product line-up of Sony. In contrast, the E-M10 II has been discontinued (but can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-M10 II was succeeded by the Olympus E-M10 III. Further information on the features and operation of the A6400 and E-M10 II can be found, respectively, in the Sony A6400 Manual (free pdf) or the online Olympus E-M10 II Manual.
Review summary
So what is the bottom line? Is there a clear favorite between the Sony A6400 and the Olympus E-M10 II? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Sony Alpha A6400:
- More detail: Offers more megapixels (24 vs 15.9MP) with a 25% higher linear resolution.
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better image quality: Scores markedly higher (10 points) in the DXO overall assessment.
- More dynamic range: Captures a larger spectrum of light and dark details (1.1 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (0.8 stops ISO advantage).
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.70x vs 0.62x).
- More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
- Faster burst: Shoots at higher frequency (11 vs 8 flaps/sec) to capture the decisive moment.
- More compact: Is smaller (120x67mm vs 120x83mm) and thus needs less room in the bag.
- Longer lasting: Can take more shots (410 versus 320) on a single battery charge.

- More modern: Reflects 3 years and 4 months of technical progress since the E-M10 II launch.
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 LCD: Has a higher resolution rear screen (1040k vs 922k dots).
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
- More affordable: Was introduced into a lower priced category (28 percent cheaper at launch).
- More heavily discounted: Has been around for much longer (launched in August 2015).
If the number of relative strengths (bullet points above) is taken as a guide, the A6400 is the clear winner of the match-up (18 : 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 sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 A6400 and the Olympus E-M10 II 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the A6400 or the E-M10 II. 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 why hands-on reviews by experts are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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 review scores listed above should be treated 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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
