DA70 and 24x36 coverage

[Godfrey DiGiorgi]

I don't know what's confusing about it. The FA-J lenses were a small  
set of modestly priced "junior" lenses in the FA series produced for  
the Film cameras.

The DA series are the latest lenses designed for the Digital cameras.

Just because a lens is optimized for a digital sensor doesn't mean  
that its image circle *has* to be too small to cover a larger format.
