Best portrait lens for the pentax k r?

For portraits on the K-r, the lens matters far more than the body. Pick a fast prime and let the window light do the rest.

• Pentax smc DA* 55mm f/1.4 SDM: about 82mm equivalent, with a wide f/1.4 for soft backgrounds. My top pick.
• Pentax smc DA 50mm f/1.8: about 75mm equivalent and the cheapest route into portraits here.
• Pentax HD FA 77mm f/1.8 Limited: about 116mm equivalent, if you want more distance from your subject.

Face a window, turn your subject slightly, and expose for the face. That will do more than any of these. For the basics, see Portraits and Your first lenses.
