Canon 6D versus Canon 7D II

The Canon EOS 6D and the Canon EOS 7D Mark II are two enthusiast cameras that were revealed to the public, respectively, in September 2012 and September 2014. Both are DSLR (Digital Single Lens Reflex) cameras that are based on a full frame (6D) and an APS-C (7D Mark II) sensor. Both cameras offer a resolution of 20 megapixel. 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 6D vs Canon 7D II

The physical size and weight of the Canon 6D and the Canon 7D II are illustrated in the side-by-side display below. Three consecutive views from the front, the top, and the rear side are shown. All size 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 6D – 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 7D II is somewhat larger (4 percent) than the Canon 6D. Moreover, the 7D Mark II is markedly heavier (18 percent) than the 6D. 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 (as in the 6D) will tend to go along with bigger and heavier lenses, while more compact options are available for the smaller-sensor camera (7D Mark II). You can find a comprehensive overview of suitable optics in the Canon EF Lens Catalog.

Concerning battery life, the 6D gets 1090 shots out of its LP-E6 battery, while the 7D Mark II can take 670 images on a single charge of its LP-E6N 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 Mark II was launched at a somewhat lower price (by 14 percent) than the 6D, which makes it more attractive for photographers on a tight budget. 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 6D vs Canon 7D II

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 more expensive and lead to bigger and heavier cameras and lenses.

Of the two cameras under consideration, the Canon 6D features a full frame sensor and the Canon 7D II an APS-C sensor. The sensor area in the 7D Mark II is 61 percent smaller. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.0 and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 6D and Canon 7D II sensor measures

Even though the 6D has a larger sensor, both cameras offer the same resolution of 20 megapixel. This implies that the 6D has a lower pixel density and larger individual pixels (with a pixel pitch of 6.57μm versus 4.10μm for the 7D Mark II), which gives it a potential advantage in terms of light gathering capacity. It should, however, be noted that the 7D Mark II is a somewhat more recent model (by 1 year and 11 months) than the 6D, and its sensor might have benefitted from technological advances during this time that at least partly compensate for the smaller pixel size.

6D versus 7D Mark II MP

For many 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 review, the 6D provides substantially higher image quality than the 7D Mark II, with an overall score that is 12 points higher. This advantage is based on 1.4 bits higher color depth, 0.3 EV in additional dynamic range, and 1.1 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 cannot only take still pictures, but also record videos. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, but the 7D Mark II provides a faster frame rate than the 6D. It can shoot movie footage at 1080/60p, while the 6D is limited to 1080/30p.

 

Feature comparison: Canon 6D vs Canon 7D II

Apart from body and sensor, cameras can and do differ across a variety of features. The 6D and the 7D 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 table below summarizes some of the other core capabilities of the Canon 6D and Canon 7D II 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 7D Mark II 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.

Review summary: Canon 6D vs Canon 7D II

So what conclusions can be drawn? Which of the two cameras – the Canon 6D or the Canon 7D II – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.


Advantages of the Canon EOS 6D:

  • Better image quality: Scores substantially higher (12 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (1.4 bits more color depth).
  • Better low-light sensitivity: Requires less light for good images (1.1 stops ISO advantage).
  • Less heavy: Is lighter (by 140g or 15 percent) and hence easier to carry around.
  • Longer lasting: Can take more shots (1090 versus 670) on a single battery charge.
  • More heavily discounted: Has been on the market for longer (launched in September 2012).


Reasons to prefer the Canon EOS 7D Mark II:

  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (10 vs 4.5 flaps/sec) to capture the decisive moment.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was released into a lower priced segment (14 percent cheaper at launch).
  • More modern: Was introduced somewhat (1 year and 11 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the match-up finishes in a tie (6 points each). 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 when reflecting and deciding on a new camera.

6D 06:06 7D Mark II

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it remains incomplete and does no justice, for example, to the way the 6D or the 7D Mark II handle or perform in practice. 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 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. Hence, a score should always be seen in the context of the camera's market launch date and its price, and comparisons of ratings among very different cameras or across long time periods have little meaning. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
