Well, yes, I hear what Mark, Godfrey and you are saying. But consider the FAJ lenses. Although very short living (are they still produced?) and with just 3 lenses - they were still full frame (proper) lenses that did't have an aperture ring...
Indeed, this is confusing. In fact, if anyone of us who has these DA lenses (40, 70) would care for a (as much as I dislike this term) full frame test, it would be most helpful. OTOH, it is known that DA 21 does *not* cover the full frame. Go figure...
