Canon 1D Mark III versus Canon 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 sensor. The 1D Mark III has a resolution of 10.1 megapixel, whereas the 5DS R provides 50.3 MP.
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. 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 1D Mark III – 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 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 find a comprehensive 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 comparisons there.

The listed 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. Then, after the new model is out, very good deals can frequently be found on the pre-owned market.
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 tent 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.
For most 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 1080/60p.
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 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 full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

The 5DS R is a current model that online retailers, such as amazon, will have in stock. In contrast, the 1D Mark III has been discontinued (but it 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.
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.
- 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 1080/60p video.
- Larger screen: Has a bigger rear LCD (3.2" vs 3.0") for image review and settings control.
- More detailed LCD: Has a higher resolution rear screen (1040k vs 230k dots).
- More compact: Is smaller (152x116mm vs 156x156.6mm) and will fit more readily into a bag.
- Less heavy: Has a lower weight (by 225g or 19 percent) and is thus easier to take along.
- More affordable: Was released into a lower priced segment (18 percent cheaper at launch).
- More modern: Reflects 7 years and 11 months of technical progress since the 1D Mark III launch.
If the count of relative strengths (bullet points above) is taken as a measure, the 5DS R is the clear winner of the contest (13 : 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.
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 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 table relays the overall verdicts of several of the most popular camera review sites. The detailed reviews can be accessed, respectively, on the websites of cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

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.
