Nikos, thanks for your efforts but my version of the 50/1.7 doesn't have an accessible filter-ring. However, I have been able to gain access by removing the 4 mount screws and lifting the chrome mount followed by the alloy ring containing the ball bearing race. Looking inside the lens I could see that a small brass tab that is held in a focussing guide slot had jumped the the slot. One of the screws had come out, even though locking varnish had been applied to its head. It was a simple matter to push the tab back into the slot and resecure the screw. The infinity position is set, the only difficulty now is to correctly reposition the aperture linkage. There is also a ball bearing providing a click-stop for the AE setting. Indeed, how did this lens get through QC!! It seems your version of the 1.7 is the well engineered 1970's heavy weight. Reborn7, your example seems identical to mine. |
