I have a Kowa Super 66 that has a jammed shutter (3-4 mm of blades protruding from margin of 85 mm lens). Does anyone know what I can do to get the lens removed? I have a 150 mm and 55 mm lenses I would like to use while the 85 mm is repaired (hopefully). Also, does anyone have any recommendations of for CLAs and repair work of Kowa Super 66s and their lenses?
