or do you mean that Pentax lost ability to develop compact FF lenses?
A 31mm is quite different from a 11mm lens; and 2 31mm would weight about 700g. You're talking about 20mm and 28mm lenses just to be unfair... but add a 11mm f/2.8 prime to the 31mm and you'll surpass whatever this DA* weights.
What I mean is that things changed since the film days, and Pentax must adapt (or perish). If you want to stay in the '90s, you can use the existing options (with some effort of finding lenses on the second hand market).
