Body comparison

An illustration of the physical size and weight of the Olympus E-M10 and the Sony A7S 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 width, height and depth measures are rounded to the nearest millimeter.

The E-M10 can be obtained in two different colors (black, silver), while the A7S II is only available in black.

Size Olympus E-M10 vs Sony A7S II
Compare E-M10 versus A7S II top
Comparison E-M10 or A7S II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7S II is notably larger (25 percent) than the Olympus E-M10. Moreover, the A7S II is substantially heavier (58 percent) than the E-M10. It is noteworthy in this context that the A7S II is splash and dust-proof, while the E-M10 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 Micro Four Thirds Lens Catalog (E-M10) and the Sony FE Lens Catalog (A7S 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 E-M10 gets 320 shots out of its BLS-5 battery, while the A7S II can take 370 images on a single charge of its NP-FW50 power pack. The power pack in the A7S II 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 would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras there.

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 E-M10 was launched at a markedly lower price (by 77 percent) than the A7S II, 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 imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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 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-M10 features a Four Thirds sensor and the Sony A7S II a full frame sensor. The sensor area in the A7S II is 276 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 1.0. The sensor in the E-M10 has a native 4:3 aspect ratio, while the one in the A7S II offers a 3:2 aspect.

Olympus E-M10 and Sony A7S II sensor measures

Despite having a smaller sensor, the Olympus E-M10 offers a higher resolution of 15.9 megapixels, compared with 12 MP of the Sony A7S II. 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 8.40μm for the A7S II). Moreover, it should be noted that the A7S II is a somewhat more recent model (by 1 year and 7 months) than the E-M10, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. Coming back to sensor resolution, it should be mentioned that the E-M10 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Olympus E-M10 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the E-M10 for good quality output (200 dots per inch) amounts to 23 x 17.3 inches or 58.5 x 43.9 cm, for very good quality (250 dpi) 18.4 x 13.8 inches or 46.8 x 35.1 cm, and for excellent quality (300 dpi) 15.4 x 11.5 inches or 39 x 29.3 cm. The corresponding values for the Sony A7S II are 21.2 x 14.2 inches or 53.8 x 36 cm for good quality, 17 x 11.3 inches or 43.1 x 28.8 cm for very good quality, and 14.1 x 9.4 inches or 35.9 x 24 cm for excellent quality prints.

The Olympus OM-D E-M10 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 7S II are ISO 100 to ISO 102400, with the possibility to increase the ISO range to 50-409600.

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.

E-M10 versus A7S II MP

For many cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under consideration, the A7S II offers substantially better image quality than the E-M10 (overall score 13 points higher). The advantage is based on 0.8 bits higher color depth, 1 EV in additional dynamic range, and 1.8 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.

One difference between the cameras concerns the presence of an on-board flash. The E-M10 has one, while the A7S II does not. While the built-in flash of the E-M10 is not very powerful, it can at times be useful as a fill-in light.

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 A7S II 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 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 writes its imaging data to SDXC cards, while the A7S II 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.

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 Olympus OM-D E-M10 and Sony Alpha 7S II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the A7S II has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The E-M10 lacks such a headphone port.

Both the E-M10 and the A7S II have been discontinued, but can regularly be found used on ebay. The E-M10 was replaced by the Olympus E-M10 II, while the A7S II was followed by the Sony A7S III. Further information on the features and operation of the E-M10 and A7S II can be found, respectively, in the Olympus E-M10 Manual (free pdf) or the online Sony A7S II Manual.

Review summary

So what conclusions can be drawn? Is the Olympus E-M10 better than the Sony A7S II or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Advantages of the Olympus OM-D E-M10:

  • More detail: Offers more megapixels (15.9 vs 12MP) with a 13% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster burst: Shoots at higher frequency (8 vs 5 flaps/sec) to capture the decisive moment.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More compact: Is smaller (119x82mm vs 127x96mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 231g or 37 percent) and hence easier to carry around.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced category (77 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in January 2014).

ilogo

Reasons to prefer the Sony Alpha 7S II:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Better image quality: Scores substantially higher (13 points) in the DXO overall evaluation.
  • More dynamic range: Captures a broader range of light and dark details (1 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1.8 stops ISO advantage).
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
  • Better sound: Can connect to an external microphone for higher quality sound recording.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More detailed viewfinder: Has higher resolution electronic viewfinder (2400k vs 1440k dots).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.58x).
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 1037k dots).
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • Longer lasting: Gets more shots (370 versus 320) out of a single battery charge.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More modern: Was introduced somewhat (1 year and 7 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the A7S II is the clear winner of the contest (17 : 10 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 before making a camera decision. 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.

E-M10 10:17 A7S II

How about other alternatives? Do the specifications of the Olympus E-M10 and the Sony A7S 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 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 shooting experience and imaging performance when actually working with the E-M10 or the A7S II. 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.

Expert reviews

This is why expert reviews are important. The adjacent summary-table relays the overall verdicts of several of the most popular camera 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.

Care should be taken when interpreting the review scores above, 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.
