Non autofocus K lens in Pentax MZ-50

[Alessandro Ronchi]

I have a pentax MZ-50 and I want to use it with my old non autofocus K lens. 
When I mount them the aperture is set to the max, and I can't read the 
exposure correcly. 
I would like to do a stop-down exposure read of the scene, but I don't know if 
it's possible. Is there any ring adapter that permits the use of K lens in 
MZ-50 KAF body?
I would like to use the lens manually, with manual aperture priority, using 
only the exposure read of the camera. Is it possible?

Thanks in advance.
