I still find it strange that the k10d doesn't have the same problem.
Do the tubes have a black finish?
Have not tried my K5 but on the k7 you need to scratch some finish off and let pin 7 short to the lens mount. Pin 7 is furthest away from the lens locking pin
This issue was raised when the K7 first came out.
Not sure why they changed the program to not allow an open circuit pin 7 for manual lenses.
