Super Takumar 1:1.4/50 Optical difference between the 8 element and 7 element version

Super Takumar 1:1.4/50 Optical difference between the 8 element and 7 element version.

In this video I will show how different the Super Takumar 1:1.4/50 is if we look into the Optical assembly, between the older 8 element, and the newer 7 element version, and there is actually many difference, much more than I would think of. Both lenses are in a good shape, so I will not do any cleaning or disassemble any other parts, but only working with the optical assembly.

REMEMBER: When takin the lens assembly apart, set small arrows on the edge on some of the lens elements, just so you will know the correct oriantation of the lens element
