Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 5D Mark III and the Canon EOS 5DS R? 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.
The physical size and weight of the Canon 5D Mark III and the Canon 5DS R are illustrated 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 size dimensions are rounded to the nearest millimeter.
In this particular case, the Canon 5D Mark III and the Canon 5DS R have exactly the same width and height, and, thus, have identically-sized bodies. However, the 5DS R is slightly lighter (2 percent) than the 5D Mark III. 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 since they do not consider the interchangeable lenses that both of these cameras require. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can compare the optics available in the Canon EF Lens Catalog.
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Any camera decision will obviously take relative prices into account. 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. The 5D Mark III was somewhat cheaper (by 5 percent) than the 5DS R at launch, but both cameras fall into the same price category. 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. 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 tend to be more expensive and lead to bigger and heavier cameras and lenses.
Both cameras under consideration feature a full frame sensor and have a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
In terms of underlying technology, both cameras are build around CMOS sensors.
While the two cameras under review share the same sensor size, the 5DS R offers a higher resolution of 50.3 megapixels, compared with 22.1 MP of the 5D Mark III. This megapixels advantage translates into a 51 percent gain in linear resolution. On the other hand, these sensor specs imply that the 5DS R has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.14μm versus 6.25μm for the 5D Mark III). However, it should be noted that the 5DS R is much more recent (by 2 years and 11 months) than the 5D Mark III, and its sensor will have benefitted from technological advances during this time that compensate for the smaller pixel size. Coming back to sensor resolution, it should be mentioned that the 5DS R has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Canon 5DS R implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 5DS R for good quality output (200 dots per inch) amounts to 43.4 x 29 inch or 110.3 x 73.6 cm, for very good quality (250 dpi) 34.8 x 23.2 inch or 88.3 x 58.8 cm, and for excellent quality (300 dpi) 29 x 19.3 inch or 73.6 x 49 cm. The corresponding values for the Canon 5D Mark III are 28.8 x 19.2 inch or 73.2 x 48.8 cm for good quality, 23 x 15.4 inch or 58.5 x 39 cm for very good quality, and 19.2 x 12.8 inch or 48.8 x 32.5 cm for excellent quality prints.
The Canon EOS 5D Mark III has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-102400. The corresponding ISO settings for the Canon EOS 5DS R are ISO 100 to ISO 6400, with the possibility to increase the ISO range to 50-12800.
For many 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 consideration, the 5DS R has a markedly higher DXO score than the 5D Mark III (overall score 5 points higher), which will translate into better image quality. The advantage is based on 0.6 bits higher color depth, 0.7 EV in additional dynamic range, and -0 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, and both provide the same movie specifications (1080/30p).
Beyond body and sensor, cameras can and do differ across a range of features. The 5D Mark III and the 5DS R are similar in the sense that both have an optical viewfinder. The latter is useful for getting a clear image for framing even in brightly lit environments. The viewfinders of both cameras offer the same field of view (100%), as well as the same magnification (0.71x).

The Canon 5DS R 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.
Concerning the storage of imaging data, both the 5D Mark III and the 5DS R write their files to Compact Flash or SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. The 5DS R supports UHS-I cards (Ultra High Speed data transfer of up to 104 MB/s), while the 5D Mark III cannot take advantage of Ultra High Speed SD cards.
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 Canon EOS 5D Mark III and Canon EOS 5DS R and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the 5D Mark III has a headphone jack, which is not present on the 5DS R This port makes it possible to attach external headphones and monitor the quality of sound during the recording process.
Both cameras feature a PC Sync terminal to control professional strobe lights, which will be appreciated by studio photographers.
The 5DS R is a recent model that features in the current product line-up of Canon. In contrast, the 5D Mark III has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 5D Mark III was succeeded by the Canon 5D Mark IV. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon website.
So what is the bottom line? Is the Canon 5D Mark III better than the Canon 5DS R or vice versa? The listing below highlights the relative strengths of the two models.
Arguments in favor of the Canon EOS 5D Mark III:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Better sound control: Has a headphone port that enables audio monitoring while recording.
- Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
- Longer lasting: Can take more shots (950 versus 700) on a single battery charge.
- More heavily discounted: Has been available for much longer (launched in March 2012).
Advantages of the Canon EOS 5DS R:
- More detail: Has more megapixels (50.3 vs 22.1MP), which boosts linear resolution by 51%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores markedly higher (5 points) in the DXO overall evaluation.
- More dynamic range: Captures a broader range of light and dark details (0.7 EV of extra DR).
- Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
- Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
- Faster buffer clearing: Has an SD card interface that supports the UHS-I standard.
- More modern: Reflects 2 years and 11 months of technical progress since the 5D Mark III launch.
If the count of relative strengths (bullet points above) is taken as a measure, the 5DS R emerges as the winner of the match-up (8 : 5 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 Canon 5D Mark III and the Canon 5DS R place the cameras among the top in their class? Find out in the latest Best DSLR Camera listing 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 partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 5D Mark III or the 5DS R. 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 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.
The above review scores should be interpreted with care, though. The ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
