@aaribaud If you're looking at being locked into one lens like a phone, and you dont want to take any photos of anything far, like birds or sports, or anything macro, then a good used Fuji x100. If youre going cheap and dont want to dive into the deep end in the future, a used fuji x-pro and a 35mm f/2 lens. If you will dive into the deep end in the future, a used Nikon or Sony mirrorless and a wide-aperture lens (35mm if crop sensor, 50mm if full frame).
