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 side-by-side display below illustrates the physical size and weight of the Canon 6D and the Canon 7D II. The two cameras are presented according to their relative size. Three consecutive perspectives from the front, the top, and the back are available. All width, height and depth measures 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 6D – represents 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 camera’s price is obviously a critical decision-making factor. The manufacturer’s suggested retail prices give an idea on the placement of the camera in the maker’s lineup and the broader market. 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. Normally, street prices remain initially close to the MSRP, but after a couple of months, the first discounts appear. 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 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. Further, a large sensor camera will give the photographer additional creative options when using shallow depth-of-field to isolate a subject from its background. On the downside, larger sensors tend to be associated with larger, more expensive camera bodies 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

Since 2007, DXO Mark has published sensor performance measurements that have been derived using a consistent methodology. 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 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 are not only capable of taking still images, but can also record movies. The two cameras under consideration both have sensors whose read-out speed is fast enough to capture moving pictures, 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 range 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 following table reports on some other key feature differences and similarities of the Canon 6D, the Canon 7D II, and comparable cameras. If you need more detail on the specs, you can find comprehensive listings, for example, in the dpreview camera hub.

One difference between the cameras concerns the presence of an on-board flash. The 7D Mark II has one, while the 6D does not. While the build-in flash of the 7D Mark II is not very powerful, it can at times be useful as a fill-in light.

The 6D writes its imaging data to SDXC cards, while the 7D Mark II uses Compact Flash or SDXC cards. The 7D Mark II features dual card slots, which can be very useful in case a memory card fails. In contrast, the 6D only has one slot.

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 is the bottom line? Is the Canon 6D better than the Canon 7D II or vice versa? A synthesis of the relative strong points of each of the models is listed below.


Reasons to prefer 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.
  • Easier file upload: Has wifi build in for automatic backup or image transfer to the web.
  • More heavily discounted: Has been on the market for longer (launched in September 2012).


Arguments in favor of the Canon EOS 7D Mark II:

  • Better video: Provides higher movie framerates (1080/60p versus 1080/30p).
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • 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.
  • Faster data transfer: Supports a more advanced USB protocol (3.0 vs 2.0).
  • Greater peace of mind: Features a second card slot as a backup in case of memory card failure.
  • 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 individual advantages (bullet points above) is taken as a guide, the 7D Mark II emerges as the winner of the match-up (9 : 7 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 when reflecting and deciding on a new camera.

6D 07:09 7D Mark II

In any case, while the comparison of technical specifications can provide a useful overview of the capabilities of different cameras, it remains partial and cannot reveal, for example, the handling experience and imaging performance when actually working with the 6D or the 7D Mark II. 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 why expert reviews are important. The adjacent table relays the overall verdicts of several of the most popular camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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. 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, please note that some of the review sites have changed their methodology and reporting over time.
