Canon 5D Mark III versus Canon 5DS R

The Canon EOS 5D Mark III and the Canon EOS 5DS R are two professional cameras that were officially introduced, respectively, in March 2012 and February 2015. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a full frame sensor. The 5D Mark III has a resolution of 22.1 megapixel, whereas the 5DS R 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: Canon 5D Mark III vs Canon 5DS R

An illustration of the physical size and weight of the Canon 5D Mark III and the Canon 5DS R is provided in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All width, height and depth measures are rounded to the nearest millimeter. You can also use the toggle button 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 – the 5D Mark III – represents the basis or 100 percent across all the size and weight measures).

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 find an overview of suitable optics in the Canon EF 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 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 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.

 

Sensor comparison: Canon 5D Mark III vs Canon 5DS R

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. 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.

Canon 5D Mark III and Canon 5DS R sensor measures

While the two cameras under review share the same sensor size, the 5DS R offers a higher resolution of 50.3 megapixel, compared with 22.1 MP of the 5D Mark III. This megapixel 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.

5D Mark III versus 5DS R MP

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"). 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. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 5DS R provides a faster frame rate than the 5D Mark III. It can shoot movie footage at 1080/60p, while the 5D Mark III is limited to 1080/30p.

 

Feature comparison: Canon 5D Mark III vs Canon 5DS R

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 table below summarizes some of the other core capabilities of the Canon 5D Mark III and Canon 5DS R in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The 5DS R is a current model that online retailers, such as amazon, will have in stock. 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.

Review summary: Canon 5D Mark III vs Canon 5DS R

So what is the bottom line? Which of the two cameras – the Canon 5D Mark III or the Canon 5DS R – has the upper hand? The listing below highlights the relative strengths of the two models.


Reasons to prefer the Canon EOS 5D Mark III:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • 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).
  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • More modern: Reflects 2 years and 11 months of technical progress since the 5D Mark III launch.

If the number of relative strengths (bullet points above) is taken as a guide, the 5DS R emerges as the winner of the match-up (6 : 4 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.

5D Mark III 04:06 5DS R

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 5D Mark III or the 5DS R 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 why expert reviews are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

The review scores listed above should be treated with care, though. The ratings are only valid when refering 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 rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
