Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus OM-D E-M1 Mark II and the Sony Cyber-shot DSC-RX10 III? 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: Olympus E-M1 II vs Sony RX10 III

The physical size and weight of the Olympus E-M1 II and the Sony RX10 III are illustrated 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 width, height and depth measures are rounded to the nearest millimeter.

Compare E-M1 II versus RX10 III top
Comparison E-M1 II or RX10 III rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX10 III is somewhat larger (3 percent) than the Olympus E-M1 II. In this context, it is worth noting that both cameras are splash and dust-proof and can, hence, be used in inclement weather conditions or harsh environments.

The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX10 III has a lens built in, whereas the E-M1 II is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can compare the optics available for the E-M1 II and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the E-M1 II gets 440 shots out of its BLH-1 battery, while the RX10 III can take 420 images on a single charge of its NP-FW50 power pack. The power pack in the RX10 III can be charged via the USB port, which can be very convenient when travelling.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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 RX10 III was launched at a lower price than the E-M1 II, despite having a lens built in. 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.

 

Sensor comparison: Olympus E-M1 II vs Sony RX10 III

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 tend to be associated with larger, more expensive camera bodies and lenses.

Of the two cameras under consideration, the Olympus E-M1 II features a Four Thirds sensor and the Sony RX10 III an one-inch sensor. The sensor area in the RX10 III is 48 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 2.0 and 2.7. The sensor in the E-M1 II has a native 4:3 aspect ratio, while the one in the RX10 III offers a 3:2 aspect.

Olympus E-M1 II and Sony RX10 III sensor measures

With 20.2MP, the E-M1 II offers a slightly higher resolution than the RX10 III (20MP), but the E-M1 II nevertheless has larger individual pixels (pixel pitch of 3.34μm versus 2.41μm for the RX10 III) due to its larger sensor. Moreover, the E-M1 II is a somewhat more recent model (by 5 months) than the RX10 III, and its sensor might 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-M1 II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The E-M1 II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

Unlike the RX10 III, the E-M1 II has the capacity to capture high quality composite images (50MP) by combining multiple shots after shifting its sensor by miniscule distances. This multi-shot, pixel-shift mode is most suitable for photography of stationary objects (landscapes, studio scenes).

The Olympus OM-D E-M1 Mark II has a native sensitivity range from ISO 200 to ISO 25600, which can be extended to ISO 64-25600. The corresponding ISO settings for the Sony Cyber-shot DSC-RX10 III are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 64-25600.

E-M1 II versus RX10 III MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 review, the E-M1 II has a notably higher overall DXO score than the RX10 III (overall score 10 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.6 bits higher color depth, 0.2 EV in additional dynamic range, and 1.5 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.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The E-M1 II has a touchscreen, while the RX10 III has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The E-M1 II 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 RX10 III 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-M1 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 E-M1 II writes its imaging data to SDXC cards, while the RX10 III uses SDXC or Memory Stick PRO Duo cards. The E-M1 II features dual card slots, which can be very useful in case a memory card fails. In contrast, the RX10 III only has one slot. The E-M1 II supports UHS-II cards (on its first slot), while the RX10 III can use UHS-I cards.

 

Connectivity comparison: Olympus E-M1 II vs Sony RX10 III

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-M1 Mark II and Sony Cyber-shot DSC-RX10 III and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

ilogo

Arguments in favor of the Sony Cyber-shot DSC-RX10 III:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Easier setting verification: Features a control panel on top to check shooting parameters.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 1037k dots).
  • Ready to shoot: Has an integrated lens, whereas the E-M1 II necessitates an extra lens.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More affordable: Was introduced at a lower price, despite coming with a built-in lens.
  • More heavily discounted: Has been on the market for longer (launched in March 2016).

If the count of relative strengths (bullet points above) is taken as a measure, the E-M1 II is the clear winner of the match-up (18 : 8 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-M1 II 18:08 RX10 III

How about other alternatives? Do the specifications of the Olympus E-M1 II and the Sony RX10 III place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Superzoom Camera listings 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 remains incomplete and does no justice, for example, to the way the E-M1 II or the RX10 III perform in practice. 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: Olympus E-M1 II vs Sony RX10 III

This is why hands-on reviews by experts are important. The adjacent summary-table relays the overall verdicts of several of the most popular 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.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

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. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
