OK let's talk about depth of field. DOF is both a function of sensor size and lens aperture. That's why small sensors even with 1.8 aperture have no bokeh comparable to 35mm at 1.8.

And anyway with very small sensors you can only get blurriness if you are extremely close to the subject, while 35mm and higher sensor formats allow for MUCH more creativity.

Bokeh is not depth of field. That’s the point.

Yes, small sensors cannot get extremely shallow depth of field. However, shallow depth of field is not bokeh. If you want to say that small sensors cannot achieve narrow depth of the field or massive subject separation or a “destroyed” background or whatever, fine. But don’t call it bokeh because that’s something else.

A lens could yield the same bokeh (blur quality) at f/2 and f/4 even though the depth of field (blur quantity) would be much different.
