Canon 7D versus Nikon D850

The Canon EOS 7D and the Nikon D850 are two digital cameras that were announced, respectively, in September 2009 and July 2017. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (7D) and a full frame (D850) sensor. The Canon has a resolution of 17.9 megapixel, whereas the Nikon provides 45.4 MP. Read on to find out how these two cameras compare with respect to their size, their sensors, their features, and their reception by expert reviewers.

Body comparison: Canon 7D vs Nikon D850

The side-by-side display below illustrates the physical size and weight of the Canon 7D and the Nikon D850. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter. You can also toggle the display 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 7D – 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 Nikon D850 is notably larger (10 percent) than the Canon 7D. Moreover, the D850 is markedly heavier (17 percent) than the 7D. 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. A larger imaging sensor will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Canon EF Lens Catalog (7D) and the Nikon Lens Catalog (D850).

Concerning battery life, the 7D gets 800 shots out of its LP-E6 battery, while the D850 can take 1840 images on a single charge of its EN-EL15a power pack.

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 camera comparisons 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 7D was launched at a markedly lower price (by 48 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: Canon 7D vs Nikon D850

The size of the sensor inside a digital camera is one of the key determinants of image quality. A large sensor will tend to have larger individual pixels that provide better low-light sensitivity, wider dynamic range, and richer color depth than smaller pixel-units 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 tend to lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 7D features an APS-C sensor and the Nikon D850 a full frame sensor. The sensor area in the D850 is 158 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.6 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 7D and Nikon D850 sensor measures

With 45.4MP, the D850 offers a higher resolution than the 7D (17.9MP), but the D850 nevertheless has marginally larger individual pixels (pixel pitch of 4.35μm versus 4.31μm for the 7D) due to its larger sensor. Moreover, the D850 is a much more recent model (by 7 years and 10 months) than the 7D, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units. 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.

7D versus D850 MP

For most cameras, data on sensor performance has been reported by DXO Mark. 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 D850 offers substantially better image quality than the 7D (overall score 34 points higher). The advantage is based on 4.4 bits higher color depth, 3.1 EV in additional dynamic range, and 1.6 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, but the D850 provides a better video resolution than the 7D. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/30p.

 

Feature comparison: Canon 7D vs Nikon D850

Apart from body and sensor, cameras can and do differ across a range of features. The 7D and the D850 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 Canon 7D and Nikon D850 in connection with corresponding information for a sample of similar cameras.

The D850 is a current model that online retailers, such as amazon, will have in stock. In contrast, the 7D has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the 7D was succeeded by the Canon 7D Mark II.

Review summary: Canon 7D vs Nikon D850

So what is the bottom line? Is there a clear favorite between the Canon 7D and the Nikon D850? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Reasons to prefer the Canon EOS 7D:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Less heavy: Is lighter (by 145g or 14 percent) and hence easier to carry around.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced category (48 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in September 2009).

ilogo

Advantages of the Nikon D850:

  • More detail: Has more megapixels (45.4 vs 17.9MP), which boosts linear resolution by 59%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores substantially higher (34 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (4.4 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (3.1 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (1.6 stops ISO advantage).
  • 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 920k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (9 vs 8 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (1840 versus 800) out of a single battery charge.
  • More modern: Reflects 7 years and 10 months of technical progress since the 7D launch.

If the count of relative strengths (bullet points above) is taken as a measure, the D850 is the clear winner of the contest (14 : 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 before making a camera decision.

7D 05:14 D850

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 7D or the D850. At times, user reviews, such as those published at amazon, address these issues in a useful manner, but such feedback is on many occasions incomplete, inconsistent, and unreliable. This is where reviews by experts come in. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparing ratings of very distinct cameras or ones that are far apart in terms of their release date have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
