Are you sure the lens is fitting properly? Some Vivitar lenses have an oversized guard beside the aperture lever, which has to be removed or cut down before use. You would be able to easily tell, as the lens would fit in the camera's mount, but it wouldn't turn and lock like a normal lens does. If you can post a picture of the Vivitar lens mount, we can also identify the issue for you.

Aside from that, I'm not sure what the issue could be. What mode are you shooting with?

Ha, or that! Why do I always forget that setting.

Thank you all for helping me out.
Selecting the "Using Aperture Ring" setting (#21 on the K-7, #27 on the K-5), and set it to 2 (allowed)...solved the issue. The 'How to use manual lens' guide is really helpful.
