I'll throw a curveball and submit that, for that particular application, the FA 43mm Limited is also a stellar choice. for my part I much prefer the slightly wider FOV.

As long as it's an F50 or FA50 F1.7 (meaning it has autofocus) it will works just like a recent lens would.
If it's an A lens, aperture control will be automatic, focus will be manual.
If it's an M or K lens (the latter is simply labeled "SMC Pentax 50mm something", without any identifying letter) it's going to be fully manual, you control the aperture on the lens and focus yourself.
