1. I think, that camera knows, that Iīm using PK/A lens, because when I set A mode (on camera) and A mode on lens, my camera allow to set the aperture and calculate time (wrong time at higher f number). When I tried unmount the lens from camera (camera was turned on), the aperture setting on display came to "---". So camera know, that lens was unplugged.
Lens have only two contacts, both looks allright.
2. "A" setting of the lens works (my opinion), but camera do not move with the aperture lever (SW problem?).

Sorry for my English :(
When I try to move with lever on the lens, aperture blades are moving smoothly.
"("push Av button" ?) " = "Av" button is on Km button for DOF control (next PASM roller). When I try to push it, aperture goes on set position (viewfinder darken) (in Manual mode) and exposition metering make the measurement correctly.
So lens is ok, I think. Problem is, that camera canīt set the correct aperture in A mode. Contacts on the lens seems to be allright.

Hello,
please can you tell me, what settings I must set on Pentax K2000(Km in Europe) to get correctly exposed picture from this lens? I have on the lens aperture ring A (automatic), on the camera, I have A (on PASM button), so I can set the aperture from the camera. But, unfortunately, when I have metering mode point, or accented center, or the third possibility and I use anything other then F2.8, the photography is badly exposed (too bright). When I set F4, photography is bright, when set F8, photography is more brighter then F4.
It is very big limitation for me. I donīt shoot only at F2.8 and fully manual mode is slowly for me, but works propertly. I set the aperture on the lens, on the camera M (manual), then push Av button and the aperture goes to set possition, Ae metering finds the correct exposition and then shoot. But this lens must works at Aperture mode with this camera, If I read the specifications of K-A mount propertly...
Can you help me?
