Is the pentax smc d fa macro 50mm f 2 8 worth it?

I think it's a good pick if you want a true macro on a Pentax K body. It's a real macro lens, autofocus, and it works on both full frame and APS-C. On a full-frame body like the Pentax K-1 or Pentax K-1 Mark II, it frames as a plain 50mm. On an APS-C body such as the Pentax K-3 Mark III, it acts like a 75mm, which is a comfortable distance for small subjects and portraits.

The lens isn't stabilised, so use decent light or a tripod for close work. I can't speak to its price here, because this page doesn't list one. If you mostly shoot people rather than close-up detail, portraits explains why a fast 50mm or 85mm may suit you better. For the bigger question of whether your body needs full frame, see is full frame worth it?.
