4th group of 3 Super Takumar f1.4/50mm

in the middle the 4th group of on early 8 element lens which consists of 3 cemented elements. The other two, to the left from a 'regular' 7 element, to the right from the 'hybrid', are thinner as they are made of only 2 elements. This proves that the 'hybrid' is a 7 element lens! The fact that it has yellowed glass also indicates that it can't be an 8 element which does not have radioactive glass which may yellow.
