The other lenses they released of late - specifically the full-frame quintet - did not seem to be equipped with electromagnetic diaphragm, else the company would've made a big deal out of it. At the same time, the K-1 (like a few other bodies) is reported as compatible with this system so... that doesn't add up.
I can understand why Nikon went for it - because there is no (effective) way of transferring mechanical aperture linkage past the tilt-shift mechanism of a PC-E lens, and leaving these lenses' aperture to be only controllable through a mechanical ring was probably deemed inappropriate for the 21st century. That was probably the reason why there are no tilt-shift lenses for Minolta/Sony and Pentax mounts - except, of course, for the fully "dumb" Samyang. Now Pentax has solved the issue, and I'm wondering if Sony is going to do the same.
