Some point-and-shoot combined shutter/aperture mechanisms are pretty decent.  I
have a Ricoh GR1 which uses a shutter/aperture with seven blades (see "The
Essential GR1 page":  http://home1.pacific.net.sg/~kennetht/GR1specs.html  ).
The Konica website unfortunately gives no specs on the hexar beyond aperture
range 2.0 to 22 and an "electromagnetic step-motor shutter" 1/250 - 30 sec.,
but even if these mechanisms are combined, the aperture could still be
reasonably circular.
