        If it's so friggin' simple, why don't you just do it and let us 
all know when we can buy your camera at Wal-Mart.

        So exactly what functionality does an auto-aperture M42 
lens/body combination have that is not gained by an aperture coupler in a 
K-mount?

        IIRC, there aren't many of the millions of M42 lenses out there 
that have open-aperture auto aperture.  Most are auto/manual stop-down 
metering.
