Sony A77 II versus Canon 7D II

The Sony Alpha SLT-A77 II and the Canon EOS 7D Mark II are two enthusiast cameras that were announced, respectively, in May 2014 and September 2014. Both are DSLR (Digital Single Lens Reflex) cameras that are equipped with an APS-C sensor. The Sony has a resolution of 24 megapixel, whereas the Canon provides 20 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 A77 II vs Canon 7D II

An illustration of the physical size and weight of the Sony A77 II and the Canon 7D II is provided in the side-by-side display below. Three successive views from the front, the top, and the rear are shown. All size 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 A77 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 7D II is notably larger (12 percent) than the Sony A77 II. Moreover, the 7D Mark II is substantially heavier (41 percent) than the A77 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. Hence, you might want to study the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.

Concerning battery life, the A77 II gets 480 shots out of its NP-FM500H battery, while the 7D Mark II can take 670 images on a single charge of its LP-E6N power pack.

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 A77 II was launched at a markedly lower price (by 33 percent) than the 7D 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: Sony A77 II vs Canon 7D II

The size of the sensor inside a digital camera is one of the key determinants 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 more expensive and lead to bigger and heavier cameras and lenses.

Both cameras under consideration feature an APS-C sensor, but their sensors differ slightly in size. The sensor area in the 7D Mark II is 8 percent smaller. As a result of these sensor size differences, the cameras have format factors, respectively, of 1.5 (A77 II) and 1.6. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.

Sony A77 II and Canon 7D II sensor measures

With 24MP, the A77 II offers a higher resolution than the 7D Mark II (20MP), but the A77 II has smaller individual pixels (pixel pitch of 3.91μm versus 4.10μm for the 7D Mark II). Moreover, the 7D Mark II is a somewhat more recent model (by 4 months) than the A77 II, and its sensor might have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixels.

Many modern cameras are not only capable of taking still images, but also of capturing video footage. Both cameras under consideration have a sensor with sufficiently fast read-out times for moving pictures, and both provide the same movie specifications (1080/60p).

 

Feature comparison: Sony A77 II vs Canon 7D II

Apart from body and sensor, cameras can and do differ across a range of features. For example, the A77 II has an electronic viewfinder (2359k dots), while the 7D Mark II 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 table below summarizes some of the other core capabilities of the Sony A77 II and Canon 7D II in connection with corresponding information for a sample of similar cameras. The full specs-sheets can be found in the camera manual or, for example, in the dpreview camera hub.

  • Faster burst: Shoots at higher frequency (12 vs 10 flaps/sec) to capture the decisive moment.
  • More compact: Is smaller (143x104mm vs 149x112mm) and thus needs less room in the bag.
  • Less heavy: Is lighter (by 263g or 29 percent) and hence easier to carry around.
  • Sharper images: Has hand-shake reducing image stabilization build-in.
  • More affordable: Was introduced into a lower priced category (33 percent cheaper at launch).
  • More heavily discounted: Has been on the market for longer (launched in May 2014).

ilogo

Reasons to prefer the Canon EOS 7D Mark II:

  • Brighter framing: Features an optical viewfinder for clear, lag-free composition.
  • Longer lasting: Gets more shots (670 versus 480) out of a single battery charge.
  • More modern: Was introduced somewhat (4 months) more recently.

If the count of individual advantages (bullet points above) is taken as a guide, the A77 II is the clear winner of the match-up (10 : 3 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.

A77 II 10:03 7D Mark II

In any case, while the specs-based evaluation of cameras is instructive in revealing their potential as photographic tools, it says nothing about, for example, the handling, responsiveness, and overall imaging quality of the A77 II and the 7D Mark II in practical situations. 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 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 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 comparisons of ratings among very different cameras or across long time periods have little meaning. It should also be noted that some of the review sites have over time altered the way they render their verdicts.
