I went to use my AM Pentac this morning, and noticed after a few twists of the aperture that the circle wasn't quite a circle - it was some weird shape - looking closer, and finally removing the front and rear elements - I noticed something wasn't right. One of the blades may now have a slight bend from trying to open and close the blades (by turning the aperture on the barrel) - thinking it would snap back into place.
I notice the end of each blade has a circular nib and there is a corresponding receptacle in the aperture assembly within the barrel - but it isn't exactly clear which nib goes into what receptacle - I have pulled 3 blades from their receptacles - I'm not sure if the others are in correctly either - I was in a warm climate recently - though the camera has been in an air conditioned environment since then - maybe the blades are sticky?
I might have to bend back that one slightly bent blade?
Hopefully someone here has had a similar experience and can offer pointers.
Perhaps SK Grimes can fix?
Thanks,
Bill
I have since unseated all the blades, and I notice they a bit oily/gummy - I'm not sure I can put this back together !!! :(
