Canon 1D Mark III vs 5DS R
The Canon EOS-1D Mark III and the Canon EOS 5DS R are two professional cameras that were announced, respectively, in February 2007 and February 2015. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-H (1D Mark III) and a full frame (5DS R) sensor. The 1D Mark III has a resolution of 10.1 megapixels, whereas the 5DS R provides 50.3 MP.
Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1D 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.
An illustration of the physical size and weight of the Canon 1D Mark III and the Canon 5DS R is provided in the side-by-side display below. The two cameras are presented according to their relative size. 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.
If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Canon 5DS R is notably smaller (28 percent) than the Canon 1D Mark III. Moreover, the 5DS R is markedly lighter (19 percent) than the 1D 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. A larger imaging sensor (as in the 5DS R) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (1D Mark III). You can compare the optics available in the Canon EF Lens Catalog.
Concerning battery life, the 1D Mark III gets 2200 shots out of its LP-E4 battery, while the 5DS R can take 700 images on a single charge of its LP-E6 power pack. As can be seen in the images above, the 1D Mark III has a battery grip built in. This facilitates image-taking in portrait orientation and gives it additional battery power. In order to provide similar functionality for the 5DS R, Canon provides the BG-E11 vertical grip as an optional accessory (see here on eBay).

Any camera decision will obviously take relative prices into account. The listed launch prices provide an indication of the market segment that the manufacturer of the cameras have been targeting. The 5DS R was launched at a somewhat lower price (by 18 percent) than the 1D Mark III, which makes it more attractive for photographers on a tight budget. 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.
The imaging sensor is at the core of digital cameras and its size is one of the main determining factors of image quality. A large sensor will generally have larger individual pixels that offer better low-light sensitivity, provide wider dynamic range, and have 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.
Of the two cameras under consideration, the Canon 1D Mark III features an APS-H sensor and the Canon 5DS R a full frame sensor. The sensor area in the 5DS R is 65 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.3 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 50.3MP, the 5DS R offers a higher resolution than the 1D Mark III (10.1MP), but the 5DS R has smaller individual pixels (pixel pitch of 4.14μm versus 7.21μm for the 1D Mark III). Yet, the 5DS R is a much more recent model (by 7 years and 11 months) than the 1D Mark III, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units. 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 inches or 110.3 x 73.6 cm, for very good quality (250 dpi) 34.8 x 23.2 inches or 88.3 x 58.8 cm, and for excellent quality (300 dpi) 29 x 19.3 inches or 73.6 x 49 cm. The corresponding values for the Canon 1D Mark III are 19.4 x 13 inches or 49.4 x 32.9 cm for good quality, 15.6 x 10.4 inches or 39.5 x 26.3 cm for very good quality, and 13 x 8.6 inches or 32.9 x 21.9 cm for excellent quality prints.
The Canon EOS-1D Mark III has a native sensitivity range from ISO 100 to ISO 3200, which can be extended to ISO 50-6400. 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 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 offers substantially better image quality than the 1D Mark III (overall score 15 points higher). The advantage is based on 1.9 bits higher color depth, 0.7 EV in additional dynamic range, and 1.1 stops in additional low light sensitivity. The following table provides an overview of the physical sensor characteristics, as well as the sensor quality measurements for a selection of comparators.

Many modern cameras cannot only take still pictures, but also record videos. The 5DS R indeed provides for movie recording, while the 1D Mark III does not. The highest resolution format that the 5DS R can use is 1080/30p.
Beyond body and sensor, cameras can and do differ across a range of features. The 1D 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%), but the viewfinder of the 5DS R has a higher magnification than the one of the 1D Mark III (0.71x vs 0.58x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 1D Mark III and Canon 5DS R in connection with corresponding information for a sample of similar cameras.

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.
The 1D Mark III writes its imaging data to Compact Flash or SDHC cards, while the 5DS R uses 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 1D 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-1D Mark III and Canon EOS 5DS R and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

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 1D Mark III has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the 1D Mark III was succeeded by the Canon 1D 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 conclusions can be drawn? Is the Canon 1D Mark III better than the Canon 5DS R or vice versa? A synthesis of the relative strong points of each of the models is listed below.
Advantages of the Canon EOS-1D Mark III:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Faster burst: Shoots at higher frequency (10 vs 5 flaps/sec) to capture the decisive moment.
- More portrait friendly: Features an integrated vertical grip for easier portrait shooting.
- Longer lasting: Can take more shots (2200 versus 700) on a single battery charge.
- More heavily discounted: Has been available for much longer (launched in February 2007).
Reasons to prefer the Canon EOS 5DS R:
- More detail: Has more megapixels (50.3 vs 10.1MP), which boosts linear resolution by 123%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores substantially higher (15 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.9 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (0.7 EV of extra DR).
- Better low-light sensitivity: Can shoot in dim conditions (1.1 stops ISO advantage).
- Broader imaging potential: Can capture not only stills but also 1080/30p video.

If the count of relative strengths (bullet points above) is taken as a measure, the 5DS R is the clear winner of the contest (17 : 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 wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro 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 1D 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 the spec-sheets of cameras can offer a general idea of their imaging potential, it remains partial and cannot reveal, for example, the shooting experience and imaging performance when actually working with the 1D 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 adjacent summary-table relays the overall verdicts of several of the most popular camera 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 assessments were made in relation to similar cameras of the same technological generation. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
