That’s an odd takeaway from the article. You can trivially switch between 12MP and 48MP. Why not just… switch to 48MP when you want the extra resolution, and otherwise stick to 12MP. Perhaps switch to 48MP when you would otherwise use your DSLR…?
They look fine to me though. If you're worried about beating "a DSLR", a medium format film camera from 1920 beats it in every aspect anyway. Read your Ken Rockwell!
