Body comparison: Sony A77 vs Canon 6D Mark II
The physical size and weight of the Sony A77 and the Canon 6D Mark 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. You can also use the toggle button 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 – 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 6D Mark II is notably larger (7 percent) than the Sony A77. Moreover, the 6D Mark II is markedly heavier (5 percent) than the A77. 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 and compare the specifications of available lenses in order to get the full picture of the size and weight of the two camera systems.
The adjacent table lists the principal physical characteristics of the two cameras alongside a wider set of alternatives.

Any camera decision will naturally be influenced heavily by the price. 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 two cameras under review were launched at the same price and fall into the same 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 vs Canon 6D Mark II
The size of the sensor inside a digital camera is one of the key determinants of image quality. All other things equal, a large sensor will have larger individual pixel-units that offer better low-light sensitivity, wider dynamic range, and richer color-depth than smaller pixels 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.
Of the two cameras under consideration, the Sony A77 features an APS-C sensor and the Canon 6D Mark II a full frame sensor. The sensor area in the 6D Mark II is 135 percent bigger. As a result of these sensor size differences, the cameras have a format factor of, respectively, 1.5 and 1.0. Both cameras have a native aspect ratio (sensor width to sensor height) of 3:2.
With 26MP, the 6D Mark II offers a higher resolution than the A77 (24MP), but the 6D Mark II nevertheless has larger individual pixels (pixel pitch of 5.76μm versus 3.91μm for the A77) due to its larger sensor. Moreover, the 6D Mark II is a much more recent model (by 5 years and 10 months) than the A77, and its sensor will have benefitted from technological advances during this time that further enhance the light gathering capacity of its pixel-units.
The 6D Mark II has on-sensor phase detect pixels, which results in fast and reliable autofocus acquisition even during video recording.
The Sony Alpha SLT-A77 has a native sensitivity range from ISO 100 to ISO 16000, which can be extended to ISO 50-25600. The corresponding ISO settings for the Canon EOS 6D Mark II are ISO 100 to ISO 40000, with the possibility to increase the ISO range to 50-102400..
For many cameras, data on sensor performance has been reported by DXO Mark. 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 6D Mark II has a markedly higher DXO score than the A77 (overall score 7 points higher), which will translate into better image quality. The advantage is based on 0.4 bits higher color depth, 1.3 EV of lower dynamic range, and 1.8 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 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 vs Canon 6D Mark II
Beyond body and sensor, cameras can and do differ across a range of features. For example, the A77 has an electronic viewfinder (2359k dots), while the 6D 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 adjacent table lists some of the other core features of the Sony A77 and Canon 6D Mark II along with similar information for a selection of comparators.

One difference between the cameras concerns the presence of an on-board flash. The A77 has one, while the 6D Mark II does not. While the built-in flash of the A77 is not very powerful, it can at times be useful as a fill-in light.Both cameras have an articulated rear screen that can be turned to be front-facing. This feature will be particularly appreciated by vloggers and photographers who are interested in taking selfies.
The A77 writes its imaging data to SDXC or Memory Stick PRO Duo cards, while the 6D Mark II uses SDXC cards.
Connectivity comparison: Sony A77 vs Canon 6D Mark II

It is notable that the 6D Mark II offers wifi support, which can be a very convenient means to transfer image data to an off-camera location. In contrast, the A77 does not offer wifi capability.
The 6D Mark II is a recent model that features in the current product line-up of Canon. In contrast, the A77 has been discontinued (but it can be found pre-owned on eBay). As a replacement in the same line of cameras, the A77 was succeeded by the Sony A77 II.
Review summary: Sony A77 vs Canon 6D Mark II
So how do things add up? Which of the two cameras – the Sony A77 or the Canon 6D Mark II – has the upper hand? Below is a summary of the relative strengths of each of the two contestants.
Advantages of the Sony Alpha SLT-A77:
- More dynamic range: Captures a larger spectrum of light and dark details (1.3 EV of extra DR).
- More framing info: Has an electronic viewfinder that displays shooting data.
- Faster shutter: Has higher mechanical shutter speed (8000/sec vs 4000/sec) to freeze action.
- Faster burst: Shoots at higher frequency (12 vs 6.5 flaps/sec) to capture the decisive moment.
- Sharper images: Has hand-shake reducing image stabilization built-in.

If the number of relative strengths (bullet points above) is taken as a guide, the 6D Mark II is the clear winner of the contest (11 : 7 points). However, the relative importance of the various individual camera aspects will vary according to personal preferences and needs, so that you might like to apply corresponding weights to the particular features before making a decision on a new camera.
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 A77 or the 6D 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.

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. Also, kindly note that some of the listed sites have over time developped their review approaches and their reporting style.
