DA70 and 24x36 coverage

[Boris Liberman]

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...
