Canon 7D versus Canon 6D

The Canon EOS 7D and the Canon EOS 6D are two enthusiast cameras that were revealed to the public, respectively, in September 2009 and September 2012. Both are DSLR (Digital Single Lens Reflex) cameras that are based on an APS-C (7D) and a full frame sensor. The 7D has a resolution of 17.9 megapixel, whereas the 6D provides 20 MP.

Body comparison

An illustration of the physical size and weight of the Canon 7D and the Canon 6D is provided in the side-by-side display below. Three consecutive perspectives from the front, the top, and the back are presented. 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 side – the 7D – represents the basis for the calculations 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 somewhat smaller (2 percent) than the Canon 7D. Moreover, the 6D is markedly lighter (10 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 (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). You can find a comprehensive overview of suitable optics in the Canon EF Lens Catalog.

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 7D was launched at a somewhat lower price (by 19 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

The imaging sensor is at the core of digital cameras and its size is one of the main determining factors 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. Furthermore, a large sensor camera will give the photographer more possibilities to use shallow depth-of-field in order to 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 7D features an APS-C sensor and the Canon 6D a full frame sensor. The sensor area in the 6D is 160 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.

Sensor size

With 20MP, the 6D offers a higher resolution than the 7D (17.9MP), but the 6D nevertheless has larger individual pixels (pixel pitch of 6.57μm versus 4.31μm for the 7D) due to its larger sensor. Moreover, the 6D is a much more recent model (by 3 years) 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.

7D versus 6D MP
Sensor resolution

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 6D offers substantially better image quality than the 7D (overall score 16 points higher). The advantage is based on 1.8 bits higher color depth, 0.4 EV in additional dynamic range, and 1.5 stops in additional low light sensitivity. The adjacent table reports on the physical sensor characteristics and the outcomes of the DXO sensor quality tests for a sample of comparator-cameras.

Many modern cameras are not only capable of taking still images, but can also record movies. Both cameras under consideration are equipped with sensors that have a sufficiently high read-out speed for moving images, and both provide the same movie specifications (1080/30p).

Feature comparison

Beyond body and sensor, cameras can and do differ across a range of features. The 7D 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 Canon 7D 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.

Both the 7D and the 6D have been discontinued, but can regularly be found used on ebay. The 7D was replaced by the Canon 7D Mark II, while the 6D was followed by the Canon 6D Mark II.

Summary

So how do things add up? Is there a clear favorite between the Canon 7D and the Canon 7D? A synthesis of the relative strong points of each of the models is listed below.


Advantages of the Canon EOS 7D:

  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • Faster burst: Shoots at higher frequency (8 vs 4.5 flaps/sec) to capture the decisive moment.
  • Easier fill-in: Is equipped with a small onboard flash to brighten deep shadow areas.
  • More affordable: Was introduced into a lower priced segment (19 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in September 2009).

Reasons to prefer the Canon EOS 6D:

  • More detail: Has more megapixels (20 vs 17.9MP), which boosts linear resolution by 6%.
  • Better image quality: Scores substantially higher (16 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (1.8 bits more color depth).
  • Better low-light sensitivity: Can shoot in dim conditions (1.5 stops ISO advantage).
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
  • Longer lasting: Gets more shots (1090 versus 800) out of a single battery charge.
  • More modern: Reflects 3 years of technical progress since the 7D launch.

If the count of relative strengths (bullet points above) is taken as a measure, the 6D emerges as the winner of the match-up (7 : 5 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.

7D 05:07 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 7D and the 6D 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 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 above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. Thus, a score needs to be put into the context of the launch date and the launch price of the camera, 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.
