Keep in mind that if you're going to be using a fast lens as the author suggests the focus depth will be paper-thin at large apertures. So you're probably not going to get that creamy bokeh in your standup unless you stand perfectly still and move only your mouth muscles.

You can really see this effect when the early mirrorless DSLRs took to market and every youtuber was using one with a fast wide open normal lens. Everything was zoomed in and out of focus resulting in queasy viewers. It took a couple of years for them to get the hang of it though.
