Many times a jammed shutter is as easy to service as a slow running one. I recommend removing the lens cells from the shutter before sending them out for service. The cells should unscrew from the shutter and use standard right hand threads, turn right to tighten, turn left to unscrew. The cells are sometimes stuck from age and you have to use a rubber strap wrench or jar opening aid to unscrew them. |
