From the Pentax press release:
"Coupled with a simple, functional design and the elimination of an
aperture ring, this new mechanism considerably improves the camera's
operability."
They are talikn about the new "Quick Shift Focus System", however, the
sentence also implies, that Pentax is trying to sell the lack of an
aperture ring as improved operability. It is even more evident in the
German press release:
"Zusammen mit dem Verzicht auf einen Blendenring f�hrt dies zu einem
erheblich verbesserten Bedienungskomfort der Kamera"
(Togehter with the renouncement of an aperture ring, this (the "Quick
Shift Focus System") leads to considerably improved easo of operation of
the camera).
Shall we never again see a new Pentax lens with aperture ring?
