Originally posted by jatrax I doubt anyone can give you a real answer without actually seeing and holding the lens. That said, unless something is actually broken, from a severe drop for example, these lenses are quite repairable. Could be nothing more than a loose screw.
However, the Pentax-A 50mm f/2 is as common as weeds in my yard so the economic way forward is to just buy a mint one off ebay. Almost certainly less expensive than paying for repair. If you want to attempt it yourself, there are several videos online showing Pentax lens disassembly. But you will need to buy or make a few special tools which puts the cost back up.
Well, I was thinking more of attempting a repair.
The lens was most likely damaged in shipping - the gap between the focus ring and aperture ring is not consistent, it looks like one side was pushed in.
