As a complete newcomer to TTL twinkie flash, I have a stupid question.  Why
does the SF20 manual tell you to transfer the lens aperture setting to the
flash when working in TTL mode?  I thought one of the points of TTL flash
metering was that lens aperture and subject reflectance were taken into
account automatically by the sensor in the camera.
