does anyone know why most of the zuiko lenes stop down to f16 where most other manufactures have similar lenses w/ f-22? is it the compact diameter of the lens?

i'm feeling cheated on my DOF....

I suspect the designs are typically diffraction-limited at F/16. Giving you smaller apertures would do no good -- you might get increased DOF (gotta think that through), but at a loss of resolution.
