I was about to join this debate and then ran the numbers and realized I still don't get this right. I was going to say it's about sensor size and bigger sensors have shallower DOF.
Here's where I go when I need a refresher - Tony Northrup's explanations:

There's a lot of criticisms of his series, but they're often shallow (they don't seem to watch his whole video) and actually end up agreeing with him.
- dpark 9y agoI'm not saying anything about sensor size or depth of field. I'm pointing out the misuse of the term "bokeh". Bokeh is not depth of field. It's the quality of out of focus areas. You want good bokeh when you have a shallow depth of field but bokeh is itself a subjective measure of quality, not quantity. Calling depth of field "bokeh" is like calling focal length "framing". https://en.wikipedia.org/wiki/Bokeh https://en.wikipedia.org/wiki/Bokeh
- frostburg 9y agoHe's sorta right in the sense that most people like a "relaxed" character in the out of focus areas which is very hard to achieve with tiny sensors and lenses (while for example basically every modern large format lens is extremely "creamy").
- dpark 9y agoIf the statement was that it’s hard to make a tiny lens for a tiny sensor with good bokeh, then I guess that could be correct (I actually don’t know if small lenses can produce pleasing bokeh). I read the comment as the common “bokeh=shallow depth of field” misunderstanding, though, because the focus was on sensor size rather than the lens.
