/fgt/ I've got an issue. Recently I got a chance to try some new k mount lenses and I noticed an issue with this 300mm. From what I understand the little blade , by the blue arrow, transfers the aperature changes to the camera. It works but I can easily wiggle it from left to right. The main issue is that the aperature ring and the one next to it (yellow lines) are loose. I can feel it notch to each f stop and I can see the blades move. But I can also move up and down a stop a little. The orange diamond is supposed to line up with infinity on the focus ring (red circle) but I can rotate the two inner rings way off of that.
I'm probably fucked but is there something I can tighten to fix this?
