First of all I donīt know exactly witch model this is. It is a Tessar Jena so I believe it is before the war? My problem is that the shutter button sometimes screws when shutting witch lead to sticking. If I screw it a bit then it will release but it will be the same after a while. I have cleaned it and it got a bit better but not good. I have not opened it yet. What do you think? Is it possible to fix? It is in good shape and take nice pictures except of this.
Try it with a cable release. I have one camera with this problem. I use the cable release and no problem. If the button sticks in I pull on the cable release.
