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.
