Best portrait lens for the pentax k 500?

For portraits on the K-500, the lens matters far more than the body. The K-500 is APS-C, so the focal lengths that work best are roughly 75mm to 130mm equivalent.

My top pick is the Pentax HD D FA* 85mm f/1.4 ED SDM AW. It frames like 128mm on full frame, a little tight, but it gives lovely background blur and separation. If you'd like something a bit wider, the Pentax smc DA* 55mm f/1.4 SDM frames like 82mm, a classic portrait length that works well in smaller rooms. For a sensible first portrait lens, the Pentax smc DA 50mm f/1.8 frames like 75mm and is a good place to start.

Whichever you pick, put your subject near a window and let the light do the work. See Portraits for more on that, and Lenses if you're building a kit from scratch.
