>>4335417Most non-high end(even some higher end ones) lenses even at low fstops/wide open may not produce super clean bokeh balls and may need to be stepped down slightly.
It's a balance of Fstop, distance to subject, focal length, distance of backdrop/background from subject.
You can get super creamy backgrounds even at f9 as long as there's nothing around/behind the subject for a while at higher focal lengths.
There's a few calculators you can use based on your lens and what aperture you're using to calculate DOF which is a lot better of a explanation and 'guide' to follow. Bokeh balls are primarily glass quality/coatings.
