One of the simplest aperture mechanisms I've seen has eight rounded aperture blades. The problem is it's impossible to get a "proper" starburst out of that lens. | |

Plenty of cheap consumer film cameras (many Kodak models, Dianas, etc.) have perfectly circular apertures of various sizes. Conversely many expensive lenses (DC Nikkors, Schneider 47mm Super Angulon XL, etc.) have relatively few straight aperture blades and produce arguably fantastic bokeh. My point is that there is no fundamental difference in manufacturing complexity/cost between an aperture with straight blades and one with curved blades. | |
