I've got a Konica Auto S2 that I've had for a couple months. I re-attached the loose rangefinder mirror, and have enjoyed the camera a lot. Recently, I discovered that the aperture blades aren't moving. Fiddling with all the adjusting rings on the barrel haven't produced any changes. Any ideas?
The aperture blades (visible from the film chamber with the camera back open) are driven by a relatively weak spring in auto mode, this is to say they have to be absolutely clean. If not they tend to cling together or even do not move at all because they are stuck. You can be sure that the latter is the case if they cannot be manually changed by turning the aperture ring. Cleaning them is not possible without dismantling the camera to some extent. My advice is that you use the search function of the forum to find out if you want to do that.
