Canon 6D Mark II vs Nikon D810
The Canon EOS 6D Mark II and the Nikon D810 are two digital cameras that were officially introduced, respectively, in June 2017 and June 2014. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a full frame sensor. The Canon has a resolution of 26 megapixels, whereas the Nikon provides 36.2 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 6D Mark II and the Nikon D810? 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 6D Mark II and the Nikon D810 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 Nikon D810 is notably larger (12 percent) than the Canon 6D Mark II. Moreover, the D810 is markedly heavier (28 percent) than the 6D 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. 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 Canon EF Lens Catalog (6D Mark II) and the Nikon Lens Catalog (D810).
The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. If you would like to visualize and compare a different camera combination, you can navigate to the CAM-parator app and make your selection from a broad list of cameras 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 6D Mark II was launched at a markedly lower price (by 39 percent) than the D810, 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.
The size of the sensor inside a digital camera is one of the key determinants 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. 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 associated with larger, more expensive camera bodies 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.
While the two cameras under review share the same sensor size, the D810 offers a higher resolution of 36.2 megapixels, compared with 26 MP of the 6D Mark II. This megapixels advantage translates into a 18 percent gain in linear resolution. On the other hand, these sensor specs imply that the D810 has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.88μm versus 5.76μm for the 6D Mark II). Moreover, it should be noted, that the 6D Mark II is much more recent (by 3 years) than the D810, and its sensor will 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 D810 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.
The resolution advantage of the Nikon D810 implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the D810 for good quality output (200 dots per inch) amounts to 36.8 x 24.6 inches or 93.5 x 62.4 cm, for very good quality (250 dpi) 29.4 x 19.6 inches or 74.8 x 49.9 cm, and for excellent quality (300 dpi) 24.5 x 16.4 inches or 62.3 x 41.6 cm. The corresponding values for the Canon 6D Mark II are 31.2 x 20.8 inches or 79.2 x 52.8 cm for good quality, 25 x 16.6 inches or 63.4 x 42.3 cm for very good quality, and 20.8 x 13.9 inches or 52.8 x 35.2 cm for excellent quality prints.
The 6D Mark II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.
The Canon EOS 6D Mark II has a native sensitivity range from ISO 100 to ISO 40000, which can be extended to ISO 50-102400. The corresponding ISO settings for the Nikon D810 are ISO 64 to ISO 12800, with the possibility to increase the ISO range to 32-51200.
Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. This service assesses and scores the color depth ("DXO Portrait"), dynamic range ("DXO Landscape"), and low-light sensitivity ("DXO Sports") of camera sensors, and also publishes an overall camera score. Of the two cameras under consideration, the D810 offers substantially better image quality than the 6D Mark II (overall score 12 points higher). The advantage is based on 1.3 bits higher color depth, 2.9 EV in additional dynamic range, and 0 stops of reduced 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 cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60p).
Apart from body and sensor, cameras can and do differ across a range of features. The 6D Mark II and the D810 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 viewfinder in the D810 offers a wider field of view (100%) than the one in the 6D Mark II (98%), so that a larger proportion of the captured image is visible in the finder. On the other hand, the viewfinder of the 6D Mark II has a higher magnification (0.72x vs 0.70x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The following table reports on some other key feature differences and similarities of the Canon 6D Mark II, the Nikon D810, and comparable cameras.

One differentiating feature between the two cameras concerns the touch sensitivity of the rear screen. The 6D Mark II has a touchscreen, while the D810 has a conventional panel. Touch control can be particularly helpful, for example, for setting the focus point.The 6D Mark II has an articulated LCD that can be turned to be front-facing. This characteristic will be appreciated by vloggers and photographers who are interested in snapping selfies. In contrast, the D810 does not have a selfie-screen.
The Canon 6D Mark II and the Nikon D810 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.
The 6D Mark II writes its imaging data to SDXC cards, while the D810 uses Compact Flash or SDXC cards. The D810 features dual card slots, which can be very useful in case a memory card fails. In contrast, the 6D Mark II only has one slot. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.
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 6D Mark II and Nikon D810 and, in particular, the interfaces the cameras (and selected comparators) provide for accessory control and data transfer.

It is notable that the D810 has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The 6D Mark II lacks such a headphone port.
Studio photographers will appreciate that the Nikon D810 (unlike the 6D Mark II) features a PC Sync socket, so that professional strobe lights can be controlled by the camera.
Travel and landscape photographers will find it useful that the 6D Mark II has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.
The 6D Mark II is a recent model that features in the current product line-up of Canon. In contrast, the D810 has been discontinued (but can be found pre-owned on eBay). As a replacement in the same line of cameras, the D810 was succeeded by the Nikon D850. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Nikon websites.
So what is the bottom line? Is there a clear favorite between the Canon 6D Mark II and the Nikon D810? Which camera is better? A synthesis of the relative strong points of each of the models is listed below.

If the count of individual advantages (bullet points above) is taken as a guide, the D810 comes out slightly ahead of the 6D Mark II (15 : 14 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 6D Mark II and the Nikon D810 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 6D Mark II and the D810 in practical situations. 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 where reviews by experts come in. The table below provides a synthesis of the camera assessments of some of the best known photo-gear 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.

Care should be taken when interpreting the review scores above, though. The ratings are only valid when referring to cameras in the same category and of the same age. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, please note that some of the review sites have changed their methodology and reporting over time.
