Fred, I'm not Paul, but A1.4X-S is configured like so... On the lens side, 3 balls out, one flat, then 2 ball out (reading clockwise) On the camera side 2 depressions, one pin out, then 3 more depression contacts (clockwise) The pin out is just that. It's a movable pin in the middle of a teflon washer for electrical isolation. It travels in and out. Do you have one? Is it stuck IN. I'd guess it needs to spring out to contack the K10 body. I can put a picture up on Picasa if you want... Regards, Bob S.
