Sony RX1R II versus Olympus E-M1
The Sony Cyber-shot DSC-RX1R II and the Olympus OM-D E-M1 are two enthusiast cameras that were officially introduced, respectively, in October 2015 and September 2013. The RX1R II is a fixed lens compact, while the E-M1 is a mirrorless interchangeable lens camera. The cameras are based on a full frame (RX1R II) and a Four Thirds sensor. The Sony has a resolution of 42.2 megapixel, whereas the Olympus provides 15.9 MP.
The side-by-side display below illustrates the physical size and weight of the Sony RX1R II and the Olympus E-M1. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures are rounded to the nearest millimeter. You can also toggle the display to switch to a percentage comparison if you prefer that the measures are being expressed in relative terms (in this case, the camera on the left side – the RX1R II – represents the basis for the calculations across all the size and weight measures).
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Olympus E-M1 is considerably larger (66 percent) than the Sony RX1R II. It is noteworthy in this context that the E-M1 is splash and dust-proof, 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 build in, whereas the E-M1 is an interchangeable lens camera that requires a separate lens. Attaching the latter will add extra weight and bulk to the setup. You can find an overview of optics for the E-M1 and their specifications in the Micro Four Thirds Lens Catalog.
The table below summarizes the key physical specs of the two cameras alongside a broader set of comparators. If you want to switch the focus of the display and review another camera pair, just select a new right or left comparator from among the camera models in the table. Alternatively, you can also move across to the CAM-parator tool and choose from the broad selection of possible comparisons there.

The listed prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. 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 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. 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 Sony RX1R II features a full frame sensor and the Olympus E-M1 a Four Thirds sensor. The sensor area in the E-M1 is 74 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 2.0. The sensor in the RX1R II has a native 3:2 aspect ratio, while the one in the E-M1 offers a 4:3 aspect.
With 42.2MP, the RX1R II offers a higher resolution than the E-M1 (15.9MP), but the RX1R II nevertheless has larger individual pixels (pixel pitch of 4.50μm versus 3.76μm for the E-M1) due to its larger sensor. Moreover, the RX1R II is a somewhat more recent model (by 2 years and 1 month) than the E-M1, 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 neither of the two cameras has an anti-alias filter installed, so they are able to capture all the detail the sensor resolves.
For most cameras, data on sensor performance has been reported by DXO Mark. This service is based on lab testing and assigns an overall score to each camera sensor, as well as ratings for dynamic range ("DXO Landscape"), color depth ("DXO Portrait"), and low-light sensitivity ("DXO Sports"). Of the two cameras under review, the RX1R II provides substantially higher image quality than the E-M1, with an overall score that is 24 points higher. This advantage is based on 2.8 bits higher color depth, 1.2 EV in additional dynamic range, and 2.1 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 also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the RX1R II provides a higher frame rate than the E-M1. It can shoot video footage at 1080/60p, while the Olympus is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a range of features. The RX1R II and the E-M1 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 Sony RX1R II, the Olympus E-M1, and comparable cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The RX1R II is a current model that online retailers, such as amazon, will have in stock. In contrast, the E-M1 has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the E-M1 was succeeded by the Olympus E-M1 II.
So how do things add up? Which of the two cameras – the Sony RX1R II or the Olympus E-M1 – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.
Reasons to prefer the Sony Cyber-shot DSC-RX1R II:
- More detail: Offers more megapixels (42.2 vs 15.9MP) with a 66% higher linear resolution.
- Better image quality: Scores substantially higher (24 points) in the DXO overall assessment.
- Richer colors: Generates images with noticeably better colors (2.8 bits more color depth).
- More dynamic range: Captures a larger spectrum of light and dark details (1.2 EV of extra DR).
- Better low-light sensitivity: Requires less light for good images (2.1 stops ISO advantage).
- Better video: Provides higher movie framerates (1080/60p vs 1080/30p).
- More detailed LCD: Has a higher resolution rear screen (1229k vs 1037k dots).
- Ready to shoot: Has a lens build-in, whereas the E-M1 requires a separate lens.
- More compact: Is smaller (113x65mm vs 130x94mm) and thus needs less room in the bag.
- More modern: Reflects 2 years and 1 month of technical progress since the E-M1 launch.
Arguments in favor of the Olympus OM-D E-M1:
- Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
- Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
- Faster burst: Shoots at higher frequency (10 vs 5 flaps/sec) to capture the decisive moment.
- More flexible: Takes interchangeable lenses and can thus be used with specialty optics.
- Longer lasting: Gets more shots (350 versus 220) out of a single battery charge.
- Better sealing: Is splash and dust sealed for shooting in inclement weather conditions.
- Sharper images: Has stabilization technology build-in to reduce the impact of hand-shake.
- More heavily discounted: Has been around for much longer (launched in September 2013).
If the number of relative strengths (bullet points above) is taken as a guide, the RX1R II emerges as the winner of the contest (10 : 8 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points.
In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the RX1R II or the E-M1 handle or perform in practice. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased. This is where reviews by experts come in. The table below summarizes the assessments of some of the best known camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, 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.
In case you are interested in seeing how other cameras pair up, just make a corresponding selection in the search boxes below. There is also a set of direct links to comparison reviews that other users of the CAM-parator app explored. If you cannot find the camera you are interested in, please send me an email, and I will try to add information on that model to the database.
