Before heading straight to the technical characteristics of each model, let’s start with comparing their physical specs. Let’s start with looking at the physical difference of the two products. Below are images that clearly show the sizes of Canon EOS 77D and Sony Alpha A7S from the front view.
Now, let’s go on and see how the reviewed models are different or similar by the top view.
After looking at these images, you should get a clear idea of each model’s dimensions and how they are different from each other. However, we are not going to stop there. The next characteristic worth looking at is the weight. Of course, not every photographer is concerned about the weight, for example, it wouldn't be a decisive point for those who shoot in a studio. However, it is still an important factor because if you happen to go on a long photo session or just love having the camera with you wherever you go, you want to be sure that the chosen model isn't too heavy.
Speaking of weight, Sony Alpha A7S is a lighter option of these two, as it weights 51g less than the Canon EOS 77D. This difference, in fact, can become a significant disadvantage for the photographers, who prefer to have their cameras with them wherever they go.
Sensor is, without a doubt, the most significant element of every digital camera. Its type, size, and resolution are the factors that define the quality of future shots. Thus, it is barely possible to pick a suitable camera without looking at these specs.
Are Canon EOS 77D and Sony Alpha A7S any different in terms of sensor type?
In fact, that's exactly what makes these two models really different. Thus, it is a good point to consider if your are choosing between these two cameras. Canon EOS 77D features a 24.0 MP APS-C sized CMOS sensor . Sony Alpha A7S, in its turn, comes with a 12.0 MP Full frame sized CMOS sensor and Bionz X processor , which makes it significantly different from the first model.
Take a look below to find the comparison of Canon EOS 77D and Sony Alpha A7S by the size of their sensors.
One more distinctive feature of compared models is the sensor size. Sony Alpha A7S is equipped with a sensor that is 0.4x larger than the one featured in Canon EOS 77D. Compared to the cameras with smaller sensor area, the ones with larger sensors ensure more control on the blurry background and depth of field if you shoot in the same aperture and focal length. Thus, the first model has a significant advantage here.
If you are interested in photography or has made a career in this field, you should know that different types of shooting actually require different camera characteristics. While one model can produce outstanding portraits, at the same time, it can be terrible for shooting landscapes, and so on. Thus, before you purchase a specific camera, it is vital to decide, which type of shooting you do most often and consider an option that suits it the most.
