Canon 5DS versus Canon 5D Mark III

The Canon EOS 5DS and the Canon EOS 5D Mark III are two professional cameras that were officially introduced, respectively, in February 2015 and March 2012. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a full frame sensor. The 5DS has a resolution of 50.3 megapixel, whereas the 5D Mark III provides 22.1 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 5DS vs Canon 5D Mark III

The side-by-side display below illustrates the physical size and weight of the Canon 5DS and the Canon 5D Mark III. Three consecutive perspectives from the front, the top, and the back are presented. 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 5DS – represents the basis or 100 percent across all the size and weight measures).

In this particular case, the Canon 5DS and the Canon 5D Mark III have exactly the same width and height, and, thus, have identically-sized bodies. However, the 5D Mark III is slightly heavier (2 percent) than the 5DS. 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 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 5DS vs Canon 5D Mark III

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. 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.

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 5DS and Canon 5D Mark III sensor measures

While the two cameras under review share the same sensor size, the 5DS 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 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). In this context, it should be noted, however, that the 5DS 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.

5DS versus 5D Mark III MP

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 5DS has a notably higher overall DXO score than the 5D Mark III (overall score 6 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.7 bits higher color depth, 0.7 EV in additional dynamic range, and 0.1 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 also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the 5DS provides a higher frame rate than the 5D Mark III. It can shoot video footage at 1080/60p, while the 5D Mark III is limited to 1080/30p.

 

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

Apart from body and sensor, cameras can and do differ across a variety of features. The 5DS and the 5D Mark III 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 5DS and Canon 5D Mark III 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 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 5DS vs Canon 5D Mark III

So how do things add up? Is the Canon 5DS better than the Canon 5D Mark III or vice versa? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Canon EOS 5DS:

  • More detail: Offers more megapixels (50.3 vs 22.1MP) with a 51% higher linear resolution.
  • Better image quality: Scores markedly higher (6 points) in the DXO overall assessment.
  • More dynamic range: Captures a larger spectrum 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.


Reasons to prefer the Canon EOS 5D Mark III:

  • Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (950 versus 700) out of a single battery charge.
  • More heavily discounted: Has been around for much longer (launched in March 2012).

If the count of relative strengths (bullet points above) is taken as a measure, the 5DS emerges as the winner of the contest (5 : 3 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.

5DS 05:03 5D Mark III

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 5DS or the 5D Mark III. 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 hands-on reviews by experts are important.

Care should be taken when interpreting the review scores above, 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 comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
