When photographers talk about the “look” of a lens, they’re often referring to the way it renders out-of-focus areas, or bokeh. Bokeh is the quality of the blur in the background of a photograph, and it can vary significantly from lens to lens. One of the factors that affects bokeh is the shape of the lens’s diaphragm blades.
Diaphragm blades are thin, metal leaves that form the opening of the lens. When you adjust the aperture of the lens, the diaphragm blades move to change the size of the opening. The shape of the diaphragm blades can affect the shape of the out-of-focus highlights in a photograph.
Lenses with more diaphragm blades typically produce more circular out-of-focus highlights, while lenses with fewer diaphragm blades produce more polygonal highlights. The number of diaphragm blades in a lens is not the only factor that affects bokeh, but it is an important one.
If you’re looking for a lens that produces beautiful bokeh, it’s important to consider the shape of the diaphragm blades. Lenses with more diaphragm blades typically produce more pleasing bokeh, but they can also be more expensive.
