Sony A7R II versus Canon 80D

The Sony Alpha A7R II and the Canon EOS 80D are two enthusiast cameras that were officially introduced, respectively, in June 2015 and February 2016. The A7R II is a mirrorless interchangeable lens camera, while the 80D is a DSLR. The cameras are based on a full frame (A7R II) and an APS-C (80D) sensor. The Sony has a resolution of 42.2 megapixel, whereas the Canon provides 24 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: Sony A7R II vs Canon 80D

The side-by-side display below illustrates the physical size and weight of the Sony A7R II and the Canon 80D. 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 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 side – the A7R II – 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 80D is notably larger (20 percent) than the Sony A7R II. Moreover, the 80D is markedly heavier (17 percent) than the A7R II. 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 will tend to go along with bigger and heavier lenses, although exceptions exist. You can find an overview of optics for the two cameras in the Sony FE Lens Catalog (A7R II) and the Canon EF Lens Catalog (80D). Mirrorless cameras, such as the Sony A7R II, have moreover the advantage that they have a relatively short flange to focal plane distance and can thus use many lenses from other systems via adapters.

Concerning battery life, the A7R II gets 290 shots out of its NP-FW50 battery, while the 80D can take 960 images on a single charge of its LP-E6N power pack.

The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

The price is, of course, an important factor in any camera decision. The retail prices at the time of the camera’s release place the model in the market relative to other models in the producer’s line-up and the competition. The 80D was launched at a markedly lower price (by 63 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: Sony A7R II vs Canon 80D

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 Sony A7R II features a full frame sensor and the Canon 80D an APS-C sensor. The sensor area in the 80D 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.

Sony A7R II and Canon 80D sensor measures

With 42.2MP, the A7R II offers a higher resolution than the 80D (24MP), but the A7R II nevertheless has larger individual pixels (pixel pitch of 4.52μm versus 3.75μm for the 80D) due to its larger sensor. However, the 80D is a somewhat more recent model (by 8 months) than the A7R II, and its sensor might have benefitted from technological advances during this time that enhance the light gathering capacity of its pixels. 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.

A7R II versus 80D MP

For many 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"). Of the two cameras under review, the A7R II provides substantially higher image quality than the 80D, with an overall score that is 19 points higher. This advantage is based on 2.4 bits higher color depth, 0.7 EV in additional dynamic range, and 1.6 stops in additional low light sensitivity. The table below summarizes the physical sensor characteristics and sensor quality findings and compares them across a set of similar cameras.

Many modern cameras cannot only take still pictures, but also record videos. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, but the A7R II provides a higher video resolution than the 80D. It can shoot video footage at 4K/30p, while the Canon is limited to 1080/60p.

 

Feature comparison: Sony A7R II vs Canon 80D

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A7R II has an electronic viewfinder (2400k dots), while the 80D 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 adjacent table lists some of the other core features of the Sony A7R II and Canon 80D 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.

The 80D is a current model that online retailers, such as amazon, will have in stock. In contrast, the A7R II has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the A7R II was succeeded by the Sony Alpha A7R III.

Review summary: Sony A7R II vs Canon 80D

So how do things add up? Is there a clear favorite between the Sony A7R II and the Canon 80D? A synthesis of the relative strong points of each of the models is listed below.

ilogo

Advantages of the Sony Alpha A7R II:

  • More detail: Offers more megapixels (42.2 vs 24MP) with a 33% higher linear resolution.
  • Maximized detail: Lacks an anti-alias filter to exploit the sensor's full resolution potential.
  • Better image quality: Scores substantially higher (19 points) in the DXO overall assessment.
  • Richer colors: Generates images with noticeably better colors (2.4 bits more color depth).
  • More dynamic range: Captures a larger spectrum of light and dark details (0.7 EV of extra DR).
  • Better low-light sensitivity: Requires less light for good images (1.6 stops ISO advantage).
  • Better video: Provides higher definition movie capture (4K/30p vs 1080/60p).
  • More framing info: Has an electronic viewfinder that displays shooting data.
  • More detailed LCD: Has a higher resolution rear screen (1229k vs 1040k dots).
  • More compact: Is smaller (127x96mm vs 139x105mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 105g or 14 percent) and hence easier to carry around.
  • More legacy lens friendly: Can take a broad range of non-native lenses via adapters.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More heavily discounted: Has been on the market for longer (launched in June 2015).

ilogo

Arguments in favor of the Canon EOS 80D:

  • Better moiré control: Has an anti-alias filter to avoid artificial patterns to appear in images.
  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Easier setting verification: Has a control panel on top to check shooting parameters.
  • More flexible LCD: Has swivel screen for odd-angle shots in portrait or landscape orientation.
  • Fewer buttons to press: Has a touchscreen to facilitate handling and shooting adjustments.
  • Faster burst: Shoots at higher frequency (7 vs 5 flaps/sec) to capture the decisive moment.
  • Longer lasting: Gets more shots (960 versus 290) out of a single battery charge.
  • Easier fill-in: Has a small integrated flash to brighten shadows of backlit subjects.
  • More affordable: Was introduced into a lower priced category (63 percent cheaper at launch).
  • More modern: Was introduced somewhat (8 months) more recently.

If the count of relative strengths (bullet points above) is taken as a measure, the A7R II is the clear winner of the match-up (14 : 10 points). However, the pertinence of the various camera strengths will differ across photographers, so that you might want to weigh individual camera traits according to their importance for your own imaging needs before making a camera decision.

A7R II 14:10 80D

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 A7R II or the 80D. 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 hands-on reviews by experts are important. The table below summarizes the assessments of some of the best known camera review sites (cameralabs, dpreview, ephotozine, imaging-resource, photographyblog).

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 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.
