New designs aren't likely to be able to go far enough.
Lets see, to get an angle of view that is more or less the same as
the 15mm f/3.5 (the widest rectilinear that Pentax makes for 35mm),
they would need to make a 10mm lens.
I really have my doubts that this is feasable with the 45 or so mm
flange to focal plane distance that the K mount has.
Also, the new lens designs being shown are slow, huge zooms.
The 16-45 is about the same size as the 28-70 f/2.8 and is a stop
slower.
