Canon 6D versus Canon 5D Mark II

The Canon EOS 6D and the Canon EOS 5D Mark II are two digital cameras that were announced, respectively, in September 2012 and September 2008. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with a full frame sensor. The 6D has a resolution of 20 megapixel, whereas the 5D Mark II provides 21 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 6D vs Canon 5D Mark II

The physical size and weight of the Canon 6D and the Canon 5D Mark II are illustrated in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All width, height and depth 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 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 5D Mark II is notably larger (8 percent) than the Canon 6D. Moreover, the 5D Mark II is markedly heavier (10 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. In this particular case, both cameras feature the same lens mount, so that they can use the same lenses. You can find an 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 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 6D was launched at a markedly lower price (by 40 percent) than the 5D Mark II, 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 6D vs Canon 5D Mark 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. 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 are more costly to manufacture and tend to lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature a full frame sensor and have a format factor (sometimes also referred to as "crop factor") of 1.0. Within the spectrum of camera sensors, this places the review cameras among the large-sensor cameras that aim for top notch image quality. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 6D and Canon 5D Mark II sensor measures

While the two cameras under review share the same sensor size, the 5D Mark II offers a slightly higher resolution of 21 megapixel, compared with 20 MP of the 6D. This megapixel advantage translates into a 3 percent gain in linear resolution. On the other hand, these sensor specs imply that the 5D Mark II has a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 6.41μm versus 6.57μm for the 6D). Moreover, it should be noted, that the 6D is much more recent (by 4 years) than the 5D Mark II, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of individual pixels.

6D versus 5D Mark II MP

For most cameras, data on sensor performance has been reported by DXO Mark. 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"). The Overall DXO ratings for the two cameras under consideration are close, suggesting that they provide similar image quality. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

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, and both provide the same movie specifications (1080/30p).

 

Feature comparison: Canon 6D vs Canon 5D Mark II

Beyond body and sensor, cameras can and do differ across a range of features. The 6D and the 5D 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 adjacent table lists some of the other core features of the Canon 6D and Canon 5D Mark II along with similar information for a selection of comparators. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

Both the 6D and the 5D Mark II have been discontinued, but can regularly be found used on eBay. The 5D Mark II was replaced by the Canon 5D Mark III, while the 6D was followed by the Canon 6D Mark II.

Review summary: Canon 6D vs Canon 5D Mark II

So what is the bottom line? Which of the two cameras – the Canon 6D or the Canon 5D Mark II – has the upper hand? The listing below highlights the relative strengths of the two models.


Arguments in favor of the Canon EOS 6D:

  • Better low-light sensitivity: Requires less light for good images (0.4 stops ISO advantage).
  • More detailed LCD: Has a higher resolution rear screen (1040k vs 920k dots).
  • Faster burst: Shoots at higher frequency (4.5 vs 3.9 flaps/sec) to capture the decisive moment.
  • Longer lasting: Can take more shots (1090 versus 850) on a single battery charge.
  • More affordable: Was introduced into a lower priced category (40 percent cheaper at launch).
  • More modern: Reflects 4 years of technical progress since the 5D Mark II launch.


Advantages of the Canon EOS 5D Mark II:

  • Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
  • More heavily discounted: Has been around for much longer (launched in September 2008).

If the number of relative strengths (bullet points above) is taken as a guide, the 6D is the clear winner of the match-up (6 : 2 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 06:02 5D 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 5D Mark II handle or perform in practice. 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 (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

Care should be taken when interpreting the review scores above, though. The ratings are only valid when refering to cameras in the same category and of the same age. 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.
