Olympus E-M5 II vs Sony RX1R II
The Olympus OM-D E-M5 Mark II and the Sony Cyber-shot DSC-RX1R II are two enthusiast cameras that were revealed to the public, respectively, in February 2015 and October 2015. The E-M5 II is a mirrorless interchangeable lens camera, while the RX1R II is a fixed lens compact. The cameras are based on a Four Thirds (E-M5 II) 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-M5 Mark II 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-M5 II 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-M5 II 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 considerably smaller (30 percent) than the Olympus E-M5 II. It is worth mentioning in this context that the E-M5 II is splash and dust resistant, while the RX1R II does not feature any corresponding weather-sealing.
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-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 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will naturally be influenced heavily by the price. 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 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 Olympus E-M5 II 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-M5 II 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-M5 II (15.9MP), but the RX1R II nevertheless has larger individual pixels (pixel pitch of 4.50μm versus 3.76μm for the E-M5 II) due to its larger sensor. Moreover, the RX1R II is a somewhat more recent model (by 8 months) than the E-M5 II, 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 RX1R II has no anti-alias filter installed, so that it can capture all the detail its 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-M5 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.
Unlike the RX1R 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-RX1R II are ISO 100 to ISO 25600, with the possibility to increase the ISO range to 50-102400.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the RX1R II offers substantially better image quality than the E-M5 II (overall score 24 points higher). The advantage is based on 2.8 bits higher color depth, 1.4 EV in additional dynamic range, and 1.9 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.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/60p).
Apart from body and sensor, cameras can and do differ across a range of features. The E-M5 II 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 adjacent table lists some of the other core features of the Olympus E-M5 II and Sony RX1R II along with similar information for a selection of comparators.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The E-M5 II has a touchscreen, while the RX1R 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 RX1R 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, the E-M5 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-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 RX1R 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 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-M5 Mark II and Sony Cyber-shot DSC-RX1R 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 RX1R II) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
The RX1R II is a recent model that features in the current product line-up of Sony. In contrast, the E-M5 II has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the E-M5 II was succeeded by the Olympus E-M5 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.
So how do things add up? Which of the two cameras – the Olympus E-M5 II or the Sony RX1R 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.
Advantages of the Olympus OM-D E-M5 Mark II:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- High quality composites: Can combine several shots after pixel-shifting its sensor.
- More flexible LCD: Has a swivel screen for odd-angle shots in portrait or landscape orientation.

- Better sealing: Is weather sealed to enable shooting in dusty or wet environments.
- Sharper images: Has hand-shake reducing image stabilization built-in.
- 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).
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%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores substantially higher (24 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (2.8 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (1.4 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (1.9 stops ISO advantage).
- More detailed LCD: Has a higher resolution rear screen (1229k vs 1037k dots).
- Ready to shoot: Has an integrated lens, whereas the E-M5 II necessitates an extra lens.
- More compact: Is smaller (113x65mm vs 124x85mm) 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 modern: Was introduced somewhat (8 months) more recently.
If the count of relative strengths (bullet points above) is taken as a measure, the E-M5 II is the clear winner of the match-up (16 : 12 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 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.
How about other alternatives? Do the specifications of the Olympus E-M5 II 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-M5 II or the RX1R II perform in practice. 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.
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], 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 are only valid when referring to cameras in the same category and of the same age. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
