Why not shift to only making 24mm & I guess 34/35mm apsc to replicate the 35 & 50mm film era.

Fujifilm has 23mm lens for their X-system; it was one of first lenses they developed.
All Fujifilm's X100 cameras are too based on the 23mm lens.
Leica too has 23 mm lenses for their APS-C mirrorless cameras. Their fixed lens cameras (X1, X2, X-Typ) have 23 or 24mm lenses. Leica's 35mm lenses for the M system are legendary.
Nikon has — five! — 24mm lenses, all in production. Plenty to choose from for use on crop cameras. Nikon also has five 35mm lenses.
Olympus and Panasonic both have 17mm lenses for their m4/3 system.
Etc.
I wish to say that it would be good if Pentax develops such lenses for their users. 24mm and 35mm are truly necessary for both FF and crop, and I hope Ricoh will finally deliver them — first time ever for Pentax in digital age.
