at a guess with an f9 you are getting the shape of the lens blades, usually bokeh shots are done with a wide open lens so you get more of a circle... thats my theory!
@kali66 I learn something new everyday here.I had to google lens blades and bokeh. I am lucky that I do not find this hexagonal bokeh displeasing. (Apparently it is not the “ perfectly smooth bokeh which is preferable “.)
@mzzhope thats great Hope :) different lenses have different arrangements of blades and optics, that is what gives a certain look to the bokeh, some of the old lenses i have are very distinctive, its fun to play.
