In Guide to Leica:

Leica 75mm f/2.4 Summarit-M Aperture Series: Bokeh for Defocused Background Point Sources

Bokeh is also shown for the full aperture series from f/2.4 - f/16 using two aperture series, one strongly defocused and one moderately defocused. See also the Veiling Flare discussion which also can be studied for bokeh behavior.

The Leica 75mm f/2.4 Summarit-M uses an 11-blade aperture. How does it behave across the aperture series?

This study might be interesting in its own right even for readers with no particular interest in the Leica 75/2.4 Summarit-M.
