Canon 6D vs Sony A7R II

The Canon EOS 6D and the Sony Alpha A7R II are two enthusiast cameras that were officially introduced, respectively, in September 2012 and June 2015. The 6D is a DSLR, while the A7R II is a mirrorless interchangeable lens camera. Both cameras are equipped with a full frame sensor. The Canon has a resolution of 20 megapixels, whereas the Sony provides 42.2 MP.

Below is an overview of the main specs of the two cameras as a starting point for the comparison.

Going beyond this snapshot of core features and characteristics, what are the differences between the Canon EOS 6D and the Sony Alpha A7R II? Which one should you buy? Read on to find out how these two cameras compare with respect to their body size, their imaging sensors, their shooting features, their input-output connections, and their reception by expert reviewers.

Body comparison

The physical size and weight of the Canon 6D and the Sony A7R II are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three consecutive views from the front, the top, and the rear side are shown. All size dimensions are rounded to the nearest millimeter.

Size Canon 6D vs Sony A7R II
Compare 6D versus A7R II top
Comparison 6D or A7R II rear

If the front view area (width x height) of the cameras is taken as an aggregate measure of their size, the Sony A7R II is notably smaller (24 percent) than the Canon 6D. Moreover, the A7R II is markedly lighter (19 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. Both cameras have similarly sized sensors, but DSLRs have a larger flange-to-focal plane distance than mirrorless cameras, which imposes contraints on the optical engineering process and generally leads to bigger and heavier lenses. You can compare the optics available for the two cameras in the Canon EF Lens Catalog (6D) and the Sony FE Lens Catalog (A7R II). Mirrorless cameras, such as the A7R II, have moreover the advantage that they can use many lenses from other systems via adapters, as they have a relatively short flange to focal plane distance.

Concerning battery life, the 6D gets 1090 shots out of its LP-E6 battery, while the A7R II can take 290 images on a single charge of its NP-FW50 power pack. The power pack in the A7R II can be charged via the USB port, which can be very convenient when travelling.

The following table provides a synthesis of the main physical specifications of the two cameras and other similar ones.

Note: Measurements and pricing do not include easily detachable parts, such as interchangeable lenses or optional viewfinders.

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 34 percent) than the A7R 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

The size of the imaging sensor is a crucial determinant 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.

Both cameras under consideration feature a full frame sensor, but their sensors differ slightly in size. They nevertheless have the same format factor of 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Canon 6D and Sony A7R II sensor measures

Despite having a slightly smaller sensor, the A7R II offers a higher resolution of 42.2 megapixels, compared with 20 MP of the 6D. This megapixels advantage comes at the cost of a higher pixel density and a smaller size of the individual pixel (with a pixel pitch of 4.52μm versus 6.57μm for the 6D). However, it should be noted that the A7R II is much more recent (by 2 years and 8 months) than the 6D, and its sensor will have benefitted from technological advances during this time that make it possible to gather light more efficiently. Coming back to sensor resolution, it should be mentioned that the A7R II has no anti-alias filter installed, so that it can capture all the detail its sensor resolves.

The resolution advantage of the Sony A7R II implies greater flexibility for cropping images or the possibility to print larger pictures. The maximum print size of the A7R II for good quality output (200 dots per inch) amounts to 39.8 x 26.5 inch or 101 x 67.4 cm, for very good quality (250 dpi) 31.8 x 21.2 inch or 80.8 x 53.9 cm, and for excellent quality (300 dpi) 26.5 x 17.7 inch or 67.3 x 44.9 cm. The corresponding values for the Canon 6D are 27.4 x 18.2 inch or 69.5 x 46.3 cm for good quality, 21.9 x 14.6 inch or 55.6 x 37.1 cm for very good quality, and 18.2 x 12.2 inch or 46.3 x 30.9 cm for excellent quality prints.

The A7R II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during live view operation.

The Canon EOS 6D has a native sensitivity range from ISO 100 to ISO 25600, which can be extended to ISO 50-102400. The Sony Alpha A7R II offers exactly the same ISO settings.

6D versus A7R II MP

Consistent information on actual sensor performance is available from DXO Mark for many cameras. 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 consideration, the A7R II offers substantially better image quality than the 6D (overall score 16 points higher). The advantage is based on 2.2 bits higher color depth, 1.8 EV in additional dynamic range, and 0.6 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 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 A7R II provides a better video resolution than the 6D. It can shoot movie footage at 4K/30p, while the Canon is limited to 1080/30p.

 

Feature comparison

Apart from body and sensor, cameras can and do differ across a variety of features. For example, the A7R II has an electronic viewfinder (2400k dots), while the 6D has an optical one. Both systems have their advantages, with the electronic viewfinder making it possible to project supplementary shooting information into the framing view, whereas the optical viewfinder offers lag-free viewing and a very clear framing image. The viewfinder in the A7R II offers a wider field of view (100%) than the one in the 6D (97%), so that a larger proportion of the captured image is visible in the finder. In addition, the viewfinder of the A7R II has a higher magnification (0.78x vs 0.71x), so that the size of the image transmitted appears closer to the size seen with the naked human eye. The table below summarizes some of the other core capabilities of the Canon 6D and Sony A7R II in connection with corresponding information for a sample of similar cameras.

One feature that is present on the 6D, but is missing on the A7R II is a top-level LCD. While being, of course, smaller than the rear screen, the control panel conveys some of the essential shooting information and can be convenient for quick and easy settings verification.

The reported shutter speed information refers to the use of the mechanical shutter. Yet, some cameras only have an electronic shutter, while others have an electronic shutter in addition to a mechanical one. In fact, the A7R II is one of those camera that have an additional electronic shutter, which makes completely silent shooting possible. However, this mode is less suitable for photographing moving objects (risk of rolling shutter) or shooting under artificial light sources (risk of flickering).

The 6D writes its imaging data to SDXC cards, while the A7R II uses SDXC or Memory Stick PRO Duo cards. Both cameras can use UHS-I cards, which provide for Ultra High Speed data transfer of up to 104 MB/s.

 

Connectivity comparison

For some imaging applications, the extent to which a camera can communicate with its environment can be an important aspect in the camera decision process.

It is notable that the A7R II has a headphone jack, which makes it possible to attach external headphones and monitor the quality of sound during the recording process. The 6D lacks such a headphone port.

Travel and landscape photographers will find it useful that the 6D has an internal geolocalization sensor and can record GPS coordinates in its EXIF data.

Both the 6D and the A7R II have been discontinued, but can regularly be found used on eBay. The 6D was replaced by the Canon 6D Mark II, while the A7R II was followed by the Sony Alpha A7R III. Further information on the two cameras (e.g. user guides, manuals), as well as related accessories, can be found on the official Canon and Sony websites.


Review summary

So how do things add up? Is the Canon 6D better than the Sony A7R II or vice versa? A synthesis of the relative strong points of each of the models is listed below.

  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Features an LCD display on top to control shooting parameters.
  • Longer lasting: Can take more shots (1090 versus 290) on a single battery charge.
  • Easier geotagging: Features an internal GPS sensor to log localization data.
  • More affordable: Was introduced into a lower priced category (34 percent cheaper at launch).
  • More heavily discounted: Has been available for much longer (launched in September 2012).

ilogo

Advantages of the Sony Alpha A7R II:

  • More detail: Has more megapixels (42.2 vs 20MP), which boosts linear resolution by 45%.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores substantially higher (16 points) in the DXO overall evaluation.
  • Richer colors: Generates noticeably more natural colors (2.2 bits more color depth).
  • More dynamic range: Captures a broader range of light and dark details (1.8 EV of extra DR).
  • Better low-light sensitivity: Can shoot in dim conditions (0.6 stops ISO advantage).
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/30p).
  • Better live-view autofocus: Features on-sensor phase-detection for more confident autofocus.
  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More complete view: Has a viewfinder with a larger field of view (100% vs 97%).
  • Larger viewfinder image: Features a viewfinder with a higher magnification (0.78x vs 0.71x).
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
  • More flexible LCD: Has a tilting screen for odd-angle shots in landscape orientation.
  • Faster shutter: Has higher mechanical shutter speed (1/8000s vs 1/4000s) to freeze action.
  • Less disturbing: Has an electronic shutter option for completely silent shooting.
  • More compact: Is smaller (127x96mm vs 145x111mm) and will fit more readily into a bag.
  • Less heavy: Has a lower weight (by 145g or 19 percent) and is thus easier to take along.
  • Easier travel charging: Can be conveniently charged via its USB port.
  • Sharper images: Has stabilization technology built-in to reduce the impact of hand-shake.
  • More legacy lens friendly: Can use many non-native lenses via adapters.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • More modern: Reflects 2 years and 8 months of technical progress since the 6D launch.

If the number of relative strengths (bullet points above) is taken as a guide, the A7R II is the clear winner of the contest (22 : 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. A professional wedding photographer will view the differences between cameras in a way that diverges from the perspective of a travel photog, and a person interested in cityscapes has distinct needs from a macro shooter. Hence, the decision which camera is best and worth buying is often a very personal one.

6D 07:22 A7R II

How about other alternatives? Do the specifications of the Canon 6D and the Sony A7R II place the cameras among the top in their class? Find out in the latest Best DSLR Camera and Best Mirrorless Interchangeable Lens Camera listings whether the two cameras rank among the cream of the crop.

In any case, while the comparison of the spec-sheets of cameras can offer a general idea of their imaging potential, it remains incomplete and does no justice, for example, to the way the 6D or the A7R II perform in practice. User reviews that are available, for instance, at amazon can sometimes shed light on these issues, but such feedback is all too often partial, inconsistent, and inaccurate.

Expert reviews

This is why expert reviews are important. The following table reports the overall ratings of the cameras as published by some of the major camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, and photographyblog). As can be seen, the professional reviewers agree in many cases on the quality of different cameras, but sometimes their assessments diverge, reinforcing the earlier point that a camera decision is often a very personal choice.

Notes: (+ +) highly recommended; (+) recommended; (o) reviewed; (-) not available.

Care should be taken when interpreting the review scores above, though. The assessments were made in relation to similar cameras of the same technological generation. A score, therefore, has to be seen in close connection to the price and market introduction time of the camera, and rating-comparisons among cameras that span long time periods or concern very differently equipped models make little sense. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
