Sony RX1R II versus Canon 5DS

The Sony Cyber-shot DSC-RX1R II and the Canon EOS 5DS are two digital cameras that were revealed to the public, respectively, in October 2015 and February 2015. The RX1R II is a fixed lens compact, while the 5DS is a DSLR. Both cameras are equipped with a full frame sensor. The Sony has a resolution of 42.2 megapixel, whereas the Canon provides 50.3 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Sony RX1R II vs Canon 5DS

The side-by-side display below illustrates the physical size and weight of the Sony RX1R II and the Canon 5DS. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the RX1R II – represents 100 percent 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 Canon 5DS is considerably larger (140 percent) than the Sony RX1R II. It is noteworthy in this context that the 5DS 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 5DS 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 5DS and their specifications in the Canon EF Lens Catalog.

Concerning battery life, the RX1R II gets 220 shots out of its NP-BX1 battery, while the 5DS can take 700 images on a single charge of its LP-E6 power pack.

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 camera comparisons there.

The price is, of course, an important factor in any camera decision. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The RX1R II was launched at a lower price than the 5DS, despite having a lens build in. 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.

 

Sensor comparison: Sony RX1R II vs Canon 5DS

The size of the imaging sensor is a crucial determinant 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. The sensor area in the 5DS is 1 percent bigger. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sony RX1R II and Canon 5DS sensor measures

With 50.3MP, the 5DS offers a higher resolution than the RX1R II (42.2MP), but the 5DS has smaller individual pixels (pixel pitch of 4.14μm versus 4.50μm for the RX1R II). It is noteworthy in this context that the RX1R II is a somewhat more recent model (by 8 months) than the 5DS, 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.

RX1R II versus 5DS MP

Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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 RX1R II has a notably higher overall DXO score than the 5DS (overall score 10 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 1.1 bits higher color depth, 1.5 EV in additional dynamic range, and 0.4 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, and both provide the same movie specifications (1080/60p).

 

Feature comparison: Sony RX1R II vs Canon 5DS

Apart from body and sensor, cameras can and do differ across a range of features. For example, the RX1R II has an electronic viewfinder (2360k dots), while the 5DS has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The table below summarizes some of the other core capabilities of the Sony RX1R II and Canon 5DS in connection with corresponding information for a sample of similar cameras.

If the number of relative strengths (bullet points above) is taken as a guide, the RX1R II emerges as the winner of the contest (13 : 10 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.

RX1R II 13:10 5DS

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the RX1R II and the 5DS in practical situations. 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 table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
