Until the OP'er does a bit of research and figures out what focal length or range of focal lengths they need this thread might as well be a laundry list of every lens ever produced by Pentax from 30mm to 200mm.
Why limit the list to Pentax? Let's see, besides the cheap Helios 58/2 and the not-so-cheap FA50/1.4, I can recommend:
* Mir-1 37/2.8 (M42)
* Yashinon-DX 50/1.7 (M42)
* Meyer Oreston 50/1.8 (M42)
* Argus-Chinon 55/1.7 (M42)
* Nikkor 85/2 (NI modded)
* Jupiter-9 85/2 (M39)
* Vivitar-Komine 90/2.8 macro (M42)
* Meyer Trioplan 100/2.8 (M42)
* Focal and Sears 135/2.8 (KA)
* Jupiter-11 135/4 (M39)
* Jupiter-21M 200/4 (M42)
But that J-21M is a bit heavy at 950g.
OK everybody, whip out your laundry lists. Be sure to mention if you want starch.
