Canon 5D Mark III versus Nikon D810
The Canon EOS 5D Mark III and the Nikon D810 are two professional cameras that were announced, respectively, in March 2012 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 22.1 megapixel, whereas the Nikon provides 36.2 MP.
The side-by-side display below illustrates the physical size and weight of the Canon 5D Mark III and the Nikon D810. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the 5D 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 Nikon D810 is somewhat larger (2 percent) than the Canon 5D Mark III. Moreover, the D810 is slightly heavier (3 percent) than the 5D 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. Yet, since both cameras are based around a full frame sensor, their respective lenses will tend to have similar dimensions and heft. You can find an overview of optics for the two cameras in the Canon EF Lens Catalog (5D Mark III) and the Nikon Lens Catalog (D810).
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 D810 was somewhat cheaper (by 6 percent) than the 5D Mark III at launch, but both cameras fall into the same price category. 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 size of the imaging sensor is a crucial determinant 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 are more costly to manufacture and tent to 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.
Despite having a slightly smaller sensor, the D810 offers a higher resolution of 36.2 megapixel, compared with 22.1 MP of the 5D Mark III. This megapixel advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.88μm versus 6.25μm for the 5D Mark III). However, it should be noted that the D810 is much more recent (by 2 years and 3 months) than the 5D Mark III, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. 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.
For most cameras, data on sensor performance has been reported by DXO Mark. 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"). Of the two cameras under consideration, the D810 offers substantially better image quality than the 5D Mark III (overall score 16 points higher). The advantage is based on 1.7 bits higher color depth, 3.1 EV in additional dynamic range, and 0.3 stops in additional 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 are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the D810 provides a faster frame rate than the 5D Mark III. It can shoot movie footage at 1080/60p, while the Canon is limited to 1080/30p.
Apart from body and sensor, cameras can and do differ across a variety of features. The 5D Mark III 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 adjacent table lists some of the other core features of the Canon 5D Mark III and Nikon D810 along with similar information for a selection of comparators. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

Both the 5D Mark III and the D810 have been discontinued, but can regularly be found used on ebay. The 5D Mark III was replaced by the Canon 5D Mark IV, while the D810 was followed by the Nikon D850.
So what is the bottom line? Which of the two cameras – the Canon 5D Mark III or the Nikon D810 – has the upper hand? A synthesis of the relative strong points of each of the models is listed below.
Arguments in favor of the Canon EOS 5D Mark III:
- Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
- Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
- Faster burst: Shoots at higher frequency (6 vs 5 flaps/sec) to capture the decisive moment.
- More heavily discounted: Has been available for much longer (launched in March 2012).
Advantages of the Nikon D810:
- More detail: Has more megapixels (36.2 vs 22.1MP), which boosts linear resolution by 28%.
- Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
- Better image quality: Scores substantially higher (16 points) in the DXO overall evaluation.
- Richer colors: Generates noticeably more natural colors (1.7 bits more color depth).
- More dynamic range: Captures a broader range of light and dark details (3.1 EV of extra DR).
- Better video: Provides higher movie framerates (1080/60p vs 1080/30p).
- More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
- Longer lasting: Gets more shots (1200 versus 950) out of a single battery charge.
- Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
- More modern: Reflects 2 years and 3 months of technical progress since the 5D Mark III launch.
If the count of relative strengths (bullet points above) is taken as a measure, the D810 is the clear winner of the contest (10 : 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 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 5D Mark III or the D810 handle or 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. This is where reviews by experts come in. 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 review scores listed above should be treated with care, 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 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.
