Can you achieve beautiful background blur with a small sensor? Yes, you can. According to this video by the Koldunov Brothers, small sensors produce more background blur than larger ones. However, you may not fully appreciate this blur because too little of it fits into the frame.
But of course, it’s more complicated than that. Small sensors often require shorter focal length lenses, which don’t blur the background as effectively. In this video, the Brothers shed light on this controversial subject.
