Well the current metaphor in lenses is you must aim for ultimate
sharpness. If you look at all the new normal lenses from Sony, Canon,
Nikon, Zeiss, Sigma, even Samyang. Their new fast 50mm f1.4 lenses are
much larger than older designs. Because it takes a lot more correction
to make them that sharp from wide open. It's not just Sony and Zeiss
doing it.
Ricoh is just following that lead. It's not like Pentax didn't
understand this in the past, they just made a classic normal lens
design, which allowed both high speed, and compact design, now that's
not good enough. Personally I think they should keep the old FA design
for those who like a more compact lens and understand that having a
softer look is desirable for portraits but I doubt they have the
manufacturing capacity to have two different 50mm designs for the same
format in production at the same time.

Of course that's just a mockup they showed as the distance window is
plugged.
Still, makes me wonder if Pentax is going to pull a Sony and go for the
prosumer market & less targeting the enthusiast.
I say that b/c the form factor / styling is reminiscent of the Zeiss line on
the Sony.
There's no need for such a large lens unless it's actually superb.
