Olympus E-M10 III vs Sony RX1R II
The Olympus OM-D E-M10 Mark III and the Sony Cyber-shot DSC-RX1R II are two digital cameras that were announced, respectively, in August 2017 and October 2015. The E-M10 III is a mirrorless interchangeable lens camera, while the RX1R II is a fixed lens compact. The cameras are based on a Four Thirds (E-M10 III) and a full frame (RX1R II) sensor. The Olympus has a resolution of 15.9 megapixels, whereas the Sony provides 42.2 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 III and the Sony Cyber-shot DSC-RX1R 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.
An illustration of the physical size and weight of the Olympus E-M10 III and the Sony RX1R 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 dimensions are rounded to the nearest millimeter.
The E-M10 III can be obtained in two different colors (black, silver), while the RX1R II 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 Sony RX1R II is notably smaller (28 percent) than the Olympus E-M10 III. In this context, it is worth noting that neither the E-M10 III nor the RX1R II are weather-sealed.
The above size and weight comparisons are to some extent incomplete and possibly misleading, as the RX1R II has a lens built in, whereas the E-M10 III 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-M10 III and their specifications in the Micro Four Thirds Lens Catalog.
Concerning battery life, the E-M10 III gets 330 shots out of its BLS-50 battery, while the RX1R II can take 220 images on a single charge of its NP-BX1 power pack. The power pack in the RX1R II can be charged via the USB port, which can be very convenient when travelling.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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.
The size of the imaging sensor is a crucial determinant of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have richer color-depth than smaller pixels 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 Olympus E-M10 III features a Four Thirds sensor and the Sony RX1R II a full frame sensor. The sensor area in the RX1R II is 280 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 III has a native 4:3 aspect ratio, while the one in the RX1R II offers a 3:2 aspect.
With 42.2MP, the RX1R II offers a higher resolution than the E-M10 III (15.9MP), but the RX1R II nevertheless has larger individual pixels (pixel pitch of 4.50μm versus 3.76μm for the E-M10 III) due to its larger sensor. However, the E-M10 III is a somewhat more recent model (by 1 year and 10 months) than the RX1R II, and its sensor might 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
The resolution advantage of the Sony RX1R II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the RX1R II for good quality output (200 dots per inch) amounts to 39.8 x 26.5 inches or 101 x 67.4 cm, for very good quality (250 dpi) 31.8 x 21.2 inches or 80.8 x 53.9 cm, and for excellent quality (300 dpi) 26.5 x 17.7 inches or 67.3 x 44.9 cm. The corresponding values for the Olympus E-M10 III 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 Olympus OM-D E-M10 Mark III 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-RX1R II are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-102400.
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"). The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-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 E-M10 III provides a higher video resolution than the RX1R II. 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 E-M10 III and the RX1R II are similar in the sense that both feature an electronic viewfinder, which is helpful when framing images in bright sunlight. Moreover, their viewfinders offer an identical resolution of 2360k dots. The following table reports on some other key feature differences and similarities of the Olympus E-M10 III, the Sony RX1R II, and comparable cameras.

One difference between the cameras concerns the presence of an on-board flash. The E-M10 III has one, while the RX1R II does not. While the built-in flash of the E-M10 III 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 E-M10 III 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 III 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 III writes its imaging data to SDXC cards, while the RX1R II uses SDXC or Memory Stick PRO Duo cards. The E-M10 III supports UHS-II cards (Ultra High Speed data transfer of up to 312 MB/s), while the RX1R II 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 III and Sony Cyber-shot DSC-RX1R II and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the RX1R II has a microphone port, which can help to improve the quality of audio recordings by attaching an external microphone. The E-M10 III does not feature such a mic input.
The RX1R II is a recent model that features in the current product line-up of Sony. In contrast, the E-M10 III has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-M10 III was succeeded by the Olympus E-M10 IV. 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 how do things add up? Is the Olympus E-M10 III better than the Sony RX1R II or vice versa? The listing below highlights the relative strengths of the two models.
Reasons to prefer the Olympus OM-D E-M10 Mark III:
- Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
- Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
- Faster burst: Shoots at higher frequency (8.6 vs 5 flaps/sec) to capture the decisive moment.

- Longer lasting: Can take more shots (330 versus 220) on a single battery charge.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
- Faster buffer clearing: Supports a more advanced SD data transfer standard (UHS-II vs UHS-I).
- More modern: Is somewhat more recent (announced 1 year and 10 months after the RX1R II).
Arguments in favor of the Sony Cyber-shot DSC-RX1R II:
- More detail: Has more megapixels (42.2 vs 15.9MP), which boosts linear resolution by 66%.
- Better image quality: Features bigger pixels on a larger sensor for higher quality imaging.
- Richer colors: The pixel size advantage translates into images with better, more accurate colors.
- More dynamic range: Larger pixels capture a wider spectrum of light and dark details.
- Better low-light sensitivity: Larger pixels means good image quality even under poor lighting.
- Better sound: Can connect to an external microphone for higher quality sound recording.
- Larger viewfinder image: Features a viewfinder with a higher magnification (0.74x vs 0.62x).
- More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
- Ready to shoot: Has an integrated lens, whereas the E-M10 III necessitates an extra lens.
- More compact: Is smaller (113x65mm vs 122x84mm) and will fit more readily into a bag.
- Easier travel charging: Can be conveniently charged via its USB port.
- Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
- More heavily discounted: Has been on the market for longer (launched in October 2015).
If the count of relative strengths (bullet points above) is taken as a measure, the RX1R II emerges as the winner of the match-up (13 : 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.
How about other alternatives? Do the specifications of the Olympus E-M10 III and the Sony RX1R II place the cameras among the top in their class? Find out in the latest Best Mirrorless Interchangeable Lens Camera and Best Prime Lens Compact Camera listings 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 incomplete and does no justice, for example, to the way the E-M10 III or the RX1R 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.
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], 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. 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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
