Description
This appears in decent shape and the aperture can be adjusted and tested with the aperture dial but when activated through the shutter command from the camera the aperture blades will sometimes stick 'closed' but at the correct aperture. So it likely has some oil that is keeping the blades from retracting when they should and or some other technical issue. Typical wear and tear- if not a tad more than normal for the age. Some minor dust but no mold or fungus or separation that I can see.
