Nikon D850 versus Canon 6D Mark II

The Nikon D850 and the Canon EOS 6D Mark II are two digital cameras that were officially introduced, respectively, in July 2017 and June 2017. 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 26 MP.

Body comparison

The physical size and weight of the Nikon D850 and the Canon 6D Mark II are illustrated in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. All width, height and depth measures 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 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 Mark II is considerably smaller (88 percent) than the Nikon D850. Moreover, the 6D Mark II is markedly lighter (24 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 Mark II).

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 Mark II was launched at a markedly lower price (by 39 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. 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.

Sensor size

Despite having a slightly smaller sensor, the Nikon D850 offers a higher resolution of 45.4 megapixel, compared with 26 MP of the Canon 6D Mark II. 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 5.76μm for the 6D Mark II). It is noteworthy in this context that the two cameras were released in close succession, so that their sensors are from the same technological generation. 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

Consistent information on actual sensor performance is available from DXO Mark for most cameras. 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 Mark II, with an overall score that is 15 points higher. This advantage is based on 2 bits higher color depth, 2.9 EV in additional dynamic range, 0.1 stops of reduced 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 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 D850 provides a higher video resolution than the 6D Mark II. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/60p.

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The D850 and the 6D Mark II 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 following table reports on some other key feature differences and similarities of the Nikon D850, the Canon 6D Mark II, and comparable cameras. If needed, the dpreview camera hub, for example, contains further detail on the cameras' specs.

Summary

So what is the bottom line? Is the Nikon D850 better than the Canon 6D Mark II or vice versa? The listing below highlights the relative strengths of the two models.


logo checkmark

Arguments in favor of the Nikon D850:

  • More detail: Offers more megapixels (45.4 vs 26MP) with a 32% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores substantially higher (15 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (2 bits more color depth).
  • More dynamic range: Captures a larger spectrum of light and dark details (2.9 EV of extra DR).
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • 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).
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (9 vs 6.5 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (1840 versus 1200) on a single battery charge.

Reasons to prefer the Canon EOS 6D Mark II:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • More compact: Is smaller (144x111mm vs 146x124mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 240g or 24 percent) and is thus easier to take along.
  • More affordable: Was introduced into a lower priced category (39 percent cheaper at launch).

If the count of individual advantages (bullet points above) is taken as a guide, the D850 is the clear winner of the match-up (11 : 5 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the D850 and the 6D Mark II 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. This is why hands-on reviews by experts are important. The following table reports the overall rankings of the cameras as published by some of the major camera review sites. The full reviews are available, respectively, at cameralabs.com, dpreview.com, ephotozine.com, imaging-resource.com, and photographyblog.com.

The above review scores should be interpreted 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. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
