what trade offs do you accept for that mirrorless camera to do all of the same functionality while still taking an above decent looking image for the vast majority of its users without all of those fancy lenses fixed or interchangeable? As the saying goes, the best came you have is the one you have on you. Only snooty photo/video types care about your comment. Most videos used by phone people are only ever viewed on that device or other similar devices of others viewing it on whatever app they shared it. To even consider them comparable is just not an honest take in the slightest. I say this as someone with several DSLRs and a couple of cinema camera bodies in the next room.
