Hello fellow Pentax users,
i bought a used lens mentioned in the threads title for about 20 bucks and tested it on my K-r. The good news is, it kinda works, the bad news is I cant change the aperture size by using the aperture ring on the lens.
Every Picture I take Shows the same DOF and same exposure times no matter if i select f11 or f2,8.
Is this the cameras fault, or the lenses faullt, and is there a way to fix this? Does the camera somehow fix the aperture to completely open? If i turn the ring when ist umounted i can see the aperture changing...
I have Firmware 1.14 if that matters...
