Seems like hey have changed the firmware (after k-x/k-7) and now it requires to short contacts to activate stopdown metering. A small aluminium foil helped. <br />Yusuf Motiwalahttps://www.blogger.com/profile/03917595697683833860noreply@blogger.comtag:blogger.com,1999:blog-34648316.post-34349661487131871152013-03-11T09:07:01.785-07:002013-03-11T09:07:01.785-07:00It works for me right out of the box.

I will suggest you to try using a K-mount lens and see if your camera setting works with K-mount in stop-down metering. I think there is a setting in setup to allow meter with aperture ring. Hope you find your solution.
