A short while back I posted here about a used Minolta 58mm lens with stuck aperture blades. Thanks to the tips I received in this forum. and the purchase of an inexpensive lens spanner, I was able to disassemble the lens, carefully clean the aperture blades, and put the darn thing back together. It even works now! Not a big deal to some of you veteran camera guys, but I made a test roll and wanted to share the results of my success.
