Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS-1D X Mark II 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.

Body comparison

The physical size and weight of the Canon 1D X Mark II 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 perspectives from the front, the top, and the back are available. 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 considerably smaller (34 percent) than the Canon 1D X Mark II. Moreover, the 5DS R is substantially lighter (39 percent) than the 1DX Mark II. 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.

Concerning battery life, the 1DX Mark II gets 1210 shots out of its Canon LP-E19 battery, while the 5DS R can take 700 images on a single charge of its Canon LP-E6 power pack. As can be seen in the images above, the 1DX Mark II 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 manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. The 5DS R was launched at a markedly lower price (by 38 percent) than the 1DX Mark II, which puts it into a different market segment. 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

The size of the sensor inside a digital camera is one of the key determinants 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 chip-set technology, the 1DX Mark II uses a more advanced image processing engine (DIGIC 6+ (Dual)) than the 5DS R (DIGIC 6 (Dual)), with benefits for noise reduction, color accuracy, and processing speed.

While the two cameras under review share the same sensor size, the 5DS R offers a higher resolution of 50.3 megapixels, compared with 20 MP of the 1DX Mark II. This megapixels advantage translates into a 59 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 6.57μm for the 1DX Mark II). Moreover, it should be noted, that the 1DX Mark II is a somewhat more recent model (by 11 months) than the 5DS R, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels. 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 X Mark II are 27.4 x 18.2 inches or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inches or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inches or 46.3 x 30.9 cm for excellent quality prints.

The 1DX Mark II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS-1D X Mark II has a native sensitivity range from ISO 100 to ISO 51200, which can be extended to ISO 50-409600. 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.

Technology-wise, both cameras are equipped with CMOS (Complementary Metal–Oxide–Semiconductor) sensors. Both cameras use a Bayer filter for capturing RGB colors on a square grid of photosensors. This arrangement is found in most digital cameras.

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar imaging performance. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the 1DX Mark II provides a higher video resolution than the 5DS R. It can shoot video footage at 4K/60p, while the 5DS R is limited to 1080/30p.

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The 1DX Mark II 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 1DX Mark II has a higher magnification than the one of the 5DS R (0.76x vs 0.71x), 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 X Mark II and Canon 5DS R in connection with corresponding information for a sample of similar cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 1DX Mark II has a touchscreen, while the 5DS R has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.

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 1DX Mark II writes its imaging data to Compact Flash or CFast 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.

Connectivity comparison

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 X Mark II 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 1DX Mark II 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.

Travel and landscape photographers will find it useful that the 1DX Mark II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the 1DX Mark II and the 5DS R have been discontinued, but can regularly be found used on ebay. The 1DX Mark II was replaced by the Canon 1DX Mark III, while the 5DS R does not have a direct successor. Further information on the features and operation of the 1DX Mark II and 5DS R can be found, respectively, in the Canon 1D X Mark II Manual (free pdf) or the online Canon 5DS R Manual.

Review summary

So what is the bottom line? Which of the two cameras – the Canon 1D X Mark II or the Canon 5DS R – has the upper hand? Is one clearly better than the other? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Canon EOS-1D X Mark II:

• Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
• More dynamic range: Captures a larger spectrum of light and dark details (1.1 EV of extra DR).
• Better low-light sensitivity: Requires less light for good images (0.5 stops ISO advantage).
• Better jpgs: Has a more modern image processing engine (DIGIC 6+ (Dual) vs DIGIC 6 (Dual)).
• Better video: Provides higher definition movie capture (4K/60p vs 1080/30p).
• Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.76x vs 0.71x).
• More detailed LCD: Has a higher resolution rear screen (1620k vs 1040k dots).
• Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
• Faster burst: Shoots at higher frequency (16 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 (1210 versus 700) on a single battery charge.
• Easier geotagging: Features an internal GPS sensor to log localization data.
• More modern: Is somewhat more recent (announced 11 months after the 5DS R).

Advantages of the Canon EOS 5DS R:

• More detail: Has more megapixels (50.3 vs 20MP), which boosts linear resolution by 59%.
• Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
• Easier time-lapse photography: Has an intervalometer built-in for low frequency shooting.
• More compact: Is smaller (152x116mm vs 158x168mm) and will fit more readily into a bag.
• Less heavy: Has a lower weight (by 600g or 39 percent) and is thus easier to take along.
• More affordable: Was introduced into a lower priced category (38 percent cheaper at launch).
• More heavily discounted: Has been on the market for longer (launched in February 2015).

If the count of relative strengths (bullet points above) is taken as a measure, the 1DX Mark II is the clear winner of the match-up (15 : 7 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 1D X Mark II 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 incomplete and does no justice, for example, to the way the 1DX Mark II or the 5DS R perform in practice. 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.

Expert reviews

This is where reviews by experts come in. The adjacent summary-table relays the overall verdicts of several of the most popular camera review sites (amateurphotographer [AP], cameralabs [CL], digitalcameraworld [DCW], dpreview [DPR], ephotozine [EPZ], photographyblog [PB]). 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.

A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, please note that some of the review sites have changed their methodology and reporting over time.
