Just to be sure.. About DAs

[Thibs]

These lens (DA ones) are really only usable on the IST-D right?
Or are these like some Sigma/Tamron, optimized for digital but you can still
use them for 24x36 ?

I just hope Pentax will make Fas with the new focus mechanism of the DAs

Thanks

DA lenses have a reduced image circle.

The 16-45 appears to be usable from somewhere around 24 to 28mm on
my ZX-5n.  I haven't run film through it to see when the vingetting
actually disappears.
