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 officially introduced, 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

The physical size and weight of the Sony A77 II and the Canon 7D II are illustrated in the side-by-side display below. The two cameras are presented according to their relative size. Three successive views from the front, the top, and the rear are shown. All size dimensions are rounded to the nearest millimeter. If you prefer, you can also use the toggle button to switch to a comparison in percentage terms (in this case, the camera on the left – the A77 II – 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 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 following table provides a synthesis of the main physical specifications of the two cameras and other similar ones. 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 camera’s price is obviously a critical decision-making factor. 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. 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.

 

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. 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 associated with larger, more expensive camera bodies 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 can also record movies. 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

Beyond 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.

One feature that differentiates the A77 II and the 7D Mark II is in-body image stabilization (IBIS). The A77 II reduces the risk of handshake-induced blur with all attached lenses, while the 7D Mark II has to rely on optical image stabilization in OIS-equipped lenses to achieve the same effect.

The A77 II writes its imaging data to SDXC or Memory Stick PRO Duo 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 A77 II only has one slot.

Review summary: Sony A77 II vs Canon 7D II

So how do things add up? Is the Sony A77 II better than the Canon 7D II or vice versa? Below is a summary of the relative strengths of each of the two contestants.

ilogo

Reasons to prefer the Sony Alpha SLT-A77 II:

  • More detail: Offers more megapixels (24 vs 20MP) with a 10% higher linear resolution.
  • 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 flexible LCD: Has full-flex screen for odd-angle shots in portrait or landscape orientation.
  • 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.
  • Easier file upload: Has wifi build in for automatic backup or image transfer to the web.
  • Easier device pairing: Supports NFC for fast wireless image transfer over short distances.
  • 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

Advantages of the Canon EOS 7D Mark II:

  • Better sound control: Has a headphone port that enables audio monitoring while recording.
  • 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.
  • 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 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 (12 : 6 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.

A77 II 12:06 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 incomplete and does no justice, for example, to the way the A77 II or the 7D 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 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 above review scores should be interpreted with care, though. The assessments were made in relation to similar cameras of the same technological generation. 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. Also, please note that some of the review sites have changed their methodology and reporting over time.
