For posterity: 1 - 54/57 Collasible, seven elements in six groups 2 - 56/68 Rigid/DR, seven elements in six groups (new optical formulation) 3 - 69/79 six element in five groups 4 - 79/94 six elements in four groups (new optical formulation) 5 - 94&up six elements in four groups (same as above) Mine is a third version which is obvious by its production date and focus mount design.
