As others have said, the K50 is fine so long as you accept the risk of the aperture block failing. Mine did, and I repaired it myself - you need care, the correct replacement solenoid, and some soldering ability.
I rarely use the 18-55mm and 50-200mm lenses, I eventually settled on the 18-135mm and HD DA(non-
plm) 55-300 as the normal lenses I carried. I've moved on to the K-3ii and K-1ii for most things, and upgraded a couple of lenses, but the 18-135 is still my go to walkaround APS-C lens. The screw drive focus is relatively noisy, but the DC motor in the 18-135 is much quieter.
