Nikon D850 versus Canon 6D

The Nikon D850 and the Canon EOS 6D are two digital cameras that were officially introduced, respectively, in July 2017 and September 2012. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a full frame sensor. The Nikon has a resolution of 45.4 megapixel, whereas the Canon provides 20 MP.

Body comparison

The physical size and weight of the Nikon D850 and the Canon 6D are illustrated 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 D850 – represents the basis or 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 6D is notably smaller (11 percent) than the Nikon D850. Moreover, the 6D is markedly lighter (23 percent) than the D850. 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 Nikon Lens Catalog (D850) and the Canon EF Lens Catalog (6D).

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 6D was launched at a markedly lower price (by 36 percent) than the D850, 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 imaging sensor is a crucial determinant 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, but their sensors differ slightly in size. The sensor area in the 6D is 1 percent bigger. 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.

Nikon D850 and Canon 6D sensor measures
Sensor size

Despite having a slightly smaller sensor, the Nikon D850 offers a higher resolution of 45.4 megapixel, compared with 20 MP of the Canon 6D. 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 4.35μm versus 6.57μm for the 6D). However, it should be noted that the D850 is much more recent (by 4 years and 10 months) than the 6D, 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 D850 has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

Sensor resolution

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 review, the D850 provides substantially higher image quality than the 6D, with an overall score that is 18 points higher. This advantage is based on 2.6 bits higher color depth, 2.7 EV in additional dynamic range, and 0.2 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 also of capturing video footage. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, but the D850 provides a higher video resolution than the 6D. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/30p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The D850 and the 6D 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 Nikon D850 and Canon 6D in connection with corresponding information for a sample of similar cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

The D850 is a current model that online retailers, such as amazon, will have in stock. In contrast, the 6D has been discontinued (but it can be found pre-owned on ebay). As a replacement in the same line of cameras, the 6D was succeeded by the Canon 6D Mark II.

Summary

So how do things add up? Is there a clear favorite between the Nikon D850 and the Nikon D850? A synthesis of the relative strong points of each of the models is listed below.


logo checkmark

Advantages of the Nikon D850:

  • More detail: Offers more megapixels (45.4 vs 20MP) with a 51% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores substantially higher (18 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (2.6 bits more color depth).
  • More dynamic range: Captures a larger spectrum of light and dark details (2.7 EV of extra DR).
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
  • 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 (2359k vs 1040k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Is equipped with a touch-sensitive rear screen to facilitate handling.
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (9 vs 4.5 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (1840 versus 1090) on a single battery charge.
  • More modern: Reflects 4 years and 10 months of technical progress since the 6D launch.

Reasons to prefer the Canon EOS 6D:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More compact: Is smaller (145x111mm vs 146x124mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 235g or 23 percent) and is thus easier to take along.
  • More affordable: Was introduced into a lower priced category (36 percent cheaper at launch).
  • More heavily discounted: Has been around for much longer (launched in September 2012).

If the count of relative strengths (bullet points above) is taken as a measure, the D850 is the clear winner of the match-up (14 : 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.

D850 14:05 6D

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the D850 and the 6D 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 following table reports the overall rankings of the cameras as published by some of the major 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 ratings were established in reference to similarly priced cameras that were available in the market at the time of the review. A score, therefore, has to be seen in close connection to the price and market introduction time 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.
