It is the result of lots of advertising, marketing and other activities that many people think 'camera' when they hear 'Canon'. But not all people think 'Canon' when they hear 'camera'

- There are other brands, starting with Nikon as the biggest rival and going over Sony, Olympus, Pentax and others, offering cameras that are partially better in specs and price than the Canon offerings. It would be quite shortsighted looking only at Canon because of personal perception. After all, in this forum we have plenty of users from all these brands and others).
Since you are new to this topic I encourage you to put the question of brand aside first. There are other things you need to consider first.
