Welcome!
I also use a K-S2, though mine is the desert beige version
. It's a really nice camera with functions that I continue to discover.

On an APS-C camera a ~50mm lens will perform really nice for portraits, I have the K 55
f1.8 and find it wonderful, the M 50
f1.7 is perhaps the most popular piece of vintage glass in the forum so it should be good as well, they can be had for real cheap if you look in the marketplace here or ebay
