What is important?
In the film days one would have a large selection of primes: 15mm, 16mm, 20mm, 24mm, fast and not so fast 28mm, 28mm PC, fast and not so fast 35mm, 35mm PC, 45mm, fast and not so fast 50mm, 50 or 60mm MACRO, fast and not so fast 85mm, 100mm, 100mm MACRO, 135mm, etc.
Nowadays Pentax offers the following DA focals: 22,5mm,
gap, slow 31,5mm,
gap, fast and not so fast 52,5mm, 52,5mm MACRO, 60mm, 75mm, fast 82,5mm, fast and not so fast 105mm,
gap, 150mm MACRO, etc.
And some full frame legacy FA lenses: fast 46,5mm LTD, fast 52,5mm, fast 64,5mm LTD, fast 115,mm LTD.
I understand if Ricśntax chooses not to make a PC lens and not to provide fast and not so fast versions of the 24mm, the 28mm, the 35mm…but these lenses 3 lenses are, in my view, very important primes that cannot be missing from a lineup (tehy don't have to be Limiteds).
On the zoom side I think we could really use a f4/50-135mm (75-202,5mm equiv.) and a f4/17-55mm (25,5-82,5mm equiv.); both lenses can be made small, reasonably light and still provide high performance.
As a side note, fixed aperture is important for those of us who shoot in manual mode.
