Filter size cannot be used to determine which version the lens is. Series VII was used until about 1976, and earlier lenses may have been converted to E55 filter threads. However if the lens has an orange 135 engraved next to the DOF scale the lens is certainly a later model using E55 filter threads. Doug Herr Sacramento http://www.wildlightphoto.com
