Vivitar 28 mm 1:2.8 Auto VMC Manual stucked Aperture

I have purchased for 8 euro a VIVITAR 28 MM 1:2.8 VMC but has a little problem the aperture is stucked.. I guess is Full Open at 2.8
I have used with my K-01 and K 5 II and is really sharp and cool.. may I use also in that way(any tips for settings) or should I try to repair(not to myself )?

Have you enabled aperture ring on both cameras? On the K-5II...
menu --> C (custom setting) --> 27. Using Aperture Ring
Once that is done, the camera will still expose with the lens wide open in other than M, X, and B modes. In auto exposure modes (P, Tv, Sv, Av, TAv) the camera defaults to Av mode at maximum aperture only.

For metering with your new lens, you will be limited to stop-down metering. This should be helpful...
