Going beyond this snapshot of core features and characteristics, what are the differences between the Nikon D800 and the Canon EOS 5DS? 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 side-by-side display below illustrates the physical size and weight of the Nikon D800 and the Canon 5DS. 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 is somewhat smaller (2 percent) than the Nikon D800. Moreover, the 5DS is markedly lighter (7 percent) than the D800. 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. Yet, since both cameras are based around a full frame sensor, their respective lenses will tend to have similar dimensions and heft. You can compare the optics available for the two cameras in the Nikon Lens Catalog (D800) and the Canon EF Lens Catalog (5DS).

Concerning battery life, the D800 gets 900 shots out of its Nikon EN-EL15 battery, while the 5DS can take 700 images on a single charge of its Canon LP-E6 power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

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 D800 was launched at a somewhat lower price (by 19 percent) than the 5DS, 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.

Sensor comparison

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. 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, but their sensors differ slightly in size. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

With 50.3MP, the 5DS offers a higher resolution than the D800 (36.2MP), but the 5DS has smaller individual pixels (pixel pitch of 4.14μm versus 4.88μm for the D800). Yet, the 5DS is a much more recent model (by 3 years) than the D800, and its sensor will have benefitted from technological advances during this time that enhance the light gathering capacity of its pixel-units.

The resolution advantage of the Canon 5DS implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the 5DS 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 Nikon D800 are 36.8 x 24.6 inches or 93.5 x 62.4 cm for good quality, 29.4 x 19.6 inches or 74.8 x 49.9 cm for very good quality, and 24.5 x 16.4 inches or 62.3 x 41.6 cm for excellent quality prints.

The Nikon D800 has a native sensitivity range from ISO 100 to ISO 6400, which can be extended to ISO 50-25600. The corresponding ISO settings for the Canon EOS 5DS 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 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 D800 has a notably higher overall DXO score than the 5DS (overall score 8 points higher), which gives it an advantage in terms of imaging quality. This advantage is based on 0.6 bits higher color depth, 2 EV in additional dynamic range, and 0.3 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 are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/30p).

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. The D800 and the 5DS 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 has a higher magnification than the one of the D800 (0.71x vs 0.70x), 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 Nikon D800 and Canon 5DS in connection with corresponding information for a sample of similar cameras.

One difference between the cameras concerns the presence of an on-board flash. The D800 has one, while the 5DS does not. While the built-in flash of the D800 is not very powerful, it can at times be useful as a fill-in light.

The Nikon D800 and the Canon 5DS both have 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.

Concerning the storage of imaging data, both the D800 and the 5DS write their files to Compact Flash or SDXC cards. Both cameras feature dual card slots, which can be very useful in case a memory card fails. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

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 Nikon D800 and Canon EOS 5DS and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D800 has a headphone jack, which is not present on the 5DS 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.

Both the D800 and the 5DS have been discontinued, but can regularly be found used on ebay. The D800 was replaced by the Nikon D810, while the 5DS does not have a direct successor. Further information on the features and operation of the D800 and 5DS can be found, respectively, in the Nikon D800 Manual (free pdf) or the online Canon 5DS Manual.

Review summary

So what conclusions can be drawn? Is the Nikon D800 better than the Canon 5DS or vice versa? A synthesis of the relative strong points of each of the models is listed below.

Reasons to prefer the Nikon D800:

• Better image quality: Scores markedly higher (8 points) in the DXO overall assessment.
• More dynamic range: Captures a larger spectrum of light and dark details (2 EV of extra DR).
• Better sound control: Has a headphone port that enables audio monitoring while recording.
• Longer lasting: Can take more shots (900 versus 700) on a single battery charge.
• Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
• More affordable: Was introduced into a lower priced segment (19 percent cheaper at launch).
• More heavily discounted: Has been available for much longer (launched in February 2012).

Advantages of the Canon EOS 5DS:

• More detail: Has more megapixels (50.3 vs 36.2MP), which boosts linear resolution by 18%.
• Larger viewfinder image: Features a viewfinder with a higher magnification (0.71x vs 0.70x).
• More detailed LCD: Has a higher resolution rear screen (1040k vs 921k dots).
• Faster burst: Shoots at higher frequency (5 vs 4 flaps/sec) to capture the decisive moment.
• More modern: Reflects 3 years of technical progress since the D800 launch.

If the count of relative strengths (bullet points above) is taken as a measure, the D800 emerges as the winner of the contest (7 : 5 points). However, the relevance of individual strengths will vary across photographers, so that you might want to apply your own weighing scheme to the summary points when reflecting and deciding on a new camera. A professional sports photographer will view the differences between cameras in a way that diverges from the perspective of a street photog, and a person interested in family portraits has distinct needs from a landscape 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 Nikon D800 and the Canon 5DS 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 specs-based evaluation of cameras can be instructive in revealing their potential as photographic tools, it says little about, for example, the shooting experience and imaging performance of the D800 and the 5DS in practical situations. User reviews, such as those found at amazon, can sometimes inform about these issues, but such feedback is often incomplete, inconsistent, and biased.

Expert reviews

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major 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.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. 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.
