Going beyond this snapshot of core features and characteristics, what are the differences between the Olympus OM-D E-M5 Mark II and the Sony Cyber-shot DSC-RX10 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: Olympus E-M5 II vs Sony RX10 II

An illustration of the physical size and weight of the Olympus E-M5 II and the Sony RX10 II 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 width, height and depth measures are rounded to the nearest millimeter.

The E-M5 II can be obtained in two different colors (black, silver), while the RX10 II is only available in black.

Compare E-M5 II versus RX10 II top
Comparison E-M5 II or RX10 II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony RX10 II is notably larger (8 percent) than the Olympus E-M5 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 II has a lens built in, whereas the E-M5 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-M5 II and their specifications in the Micro Four Thirds Lens Catalog.

Concerning battery life, the E-M5 II gets 310 shots out of its BLN-1 battery, while the RX10 II can take 400 images on a single charge of its NP-FW50 power pack. The power pack in the RX10 II 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 retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. 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.

 

Sensor comparison: Olympus E-M5 II vs Sony RX10 II

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. Moreover, a large sensor camera will give the photographer more control over depth-of-field in the image and, thus, the ability to better 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-M5 II features a Four Thirds sensor and the Sony RX10 II an one-inch sensor. The sensor area in the RX10 II 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-M5 II has a native 4:3 aspect ratio, while the one in the RX10 II offers a 3:2 aspect.

Olympus E-M5 II and Sony RX10 II sensor measures

Despite having a smaller sensor, the RX10 II offers a higher resolution of 20 megapixels, compared with 15.9 MP of the E-M5 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 2.41μm versus 3.76μm for the E-M5 II). However, it should be noted that the RX10 II is a somewhat more recent model (by 4 months) than the E-M5 II, and its sensor might have benefitted from technological advances during this time that partly offset its pixel-size disadvantage.

The resolution advantage of the Sony RX10 II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX10 II for good quality output (200 dots per inch) amounts to 27.4 x 18.2 inch or 69.5 x 46.3 cm, for very good quality (250 dpi) 21.9 x 14.6 inch or 55.6 x 37.1 cm, and for excellent quality (300 dpi) 18.2 x 12.2 inch or 46.3 x 30.9 cm. The corresponding values for the Olympus E-M5 II are 23 x 17.3 inch or 58.5 x 43.9 cm for good quality, 18.4 x 13.8 inch or 46.8 x 35.1 cm for very good quality, and 15.4 x 11.5 inch or 39 x 29.3 cm for excellent quality prints.

Unlike the RX10 II, the E-M5 II has the capacity to capture high quality composite images (40MP) 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-M5 Mark II 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 Cyber-shot DSC-RX10 II are ISO 100 to ISO 12800, with the possibility to increase the ISO range to 64-25600.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The E-M5 II has a touchscreen, while the RX10 II has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

The E-M5 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 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-M5 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-M5 II writes its imaging data to SDXC cards, while the RX10 II uses SDXC or Memory Stick PRO Duo cards. The E-M5 II supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the RX10 II can use UHS-I cards (up to 104 MB/s).

 

Connectivity comparison: Olympus E-M5 II vs Sony RX10 II

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-M5 Mark II and Sony Cyber-shot DSC-RX10 II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

Studio photographers will appreciate that the Olympus E-M5 II (unlike the RX10 II) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.

The E-M5 II is a recent model that features in the current product line-up of Olympus. In contrast, the RX10 II has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the RX10 II was succeeded by the Sony RX10 III. 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.


Review summary: Olympus E-M5 II vs Sony RX10 II

So what conclusions can be drawn? Which of the two cameras – the Olympus E-M5 II or the Sony RX10 II – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Arguments in favor of the Olympus OM-D E-M5 Mark II:

  • High quality composites: Can combine several shots after pixel-shifting its sensor.
  • Better low-light sensitivity: Requires less light for good images (0.7 stops ISO advantage).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.74x vs 0.70x).
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • More selfie-friendly: Has an articulated screen that can be turned to be front-facing.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/3200s) to freeze action.
  • Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
  • More flexible: Accepts interchangeable lenses, so that lens characteristics can be altered.
  • Better studio light control: Has a PC Sync socket to connect to professional strobe lights.
  • Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
  • More heavily discounted: Has been on the market for longer (launched in February 2015).

ilogo

Reasons to prefer the Sony Cyber-shot DSC-RX10 II:

  • More detail: Has more megapixels (20 vs 15.9MP), which boosts linear resolution by 14%.
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • 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).
  • Faster burst: Shoots at higher frequency (14 vs 10 flaps/sec) to capture the decisive moment.
  • Ready to shoot: Has an integrated lens, whereas the E-M5 II necessitates an extra lens.
  • Longer lasting: Gets more shots (400 versus 310) out of a single battery charge.
  • 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 modern: Was introduced somewhat (4 months) more recently.

If the number of relative strengths (bullet points above) is taken as a guide, the E-M5 II comes out slightly ahead of the RX10 II (12 : 11 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

E-M5 II 12:11 RX10 II

How about other alternatives? Do the specifications of the Olympus E-M5 II and the Sony RX10 II place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Travel-Zoom 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-M5 II or the RX10 II 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-M5 II vs Sony RX10 II

This is why expert reviews are important. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
