I have checked my KPR lens and I do see a pin at about 4:30. The pin is very small though. Plus there is another pin at about 6:00 position that is bigger than the 4:30 pin. I can remove the 4:30 pin but I want to make sure I am not removing an actual contact. This lens has the A setting so I assume that some of the contacts are for the aperture information being sent to the camera.
Attached is the picture with pins circled.

Thanks.
