Mark's Soligor 50mm F1.9 Miranda mount sn K4863665 lensRemind me never to try and fix a lens again. This one had a sticky diaphragm. I watched a couple of YouTube videos, and I have all the right tools. Unfortunately the lens didn't resemble the videos at all, there seem to be hundreds of TINY screws, and I couldn't find the diaphragm blades till I had it completely apart. Then I found all the pins had been sheared out of the blades. It's a rare, hard to find lens that actuated the aperture by half-pressing the shutter button. A linkage on the lens rested over the shutter button. So next time I have a rare, sick lens I'm just gonna bag it and display it.
