Thank you both for your answers. You are right. The diaphragm is stuck. I pushed the DOF preview button many (40+) times at F32 and I can see through the lens that it only closes a tiny bit but not what it should.

I also tapped the lens in the palm of my hand a few times trying to see if something is lodged in the diaphragm but that did not help either.

Next step is to go through a local lens repair shop to get this fixed. It's a great lens and probably worth the repair cost.
