Sorry that I don't have any info on the MZ-6, but I think you're barking up the wrong tree. All FA lenses can transmit the exact aperture. Whether or not the camera use it depends on the camera. Probably also reported apertures transmitted from the lens varies with the price of the lens. Eg,. Canon non-L lenses set aperture in 1/4 stops while the L-lenses use 1/12 of a stop. So the differences in "accurate" apertures is probably a function of whats coded into the lens CPU.
I don't believe that the MZ-S has FA3 mount. The specification sheet says KAF2 and I cannot find any reason why they would spread desinformation. I wouldn't hold my breath for KAF3 mount to be shown at Photokina either (I would love to be proven wrong though). When or if such a mount appears, my guess is that it will for a new series of cameras.
