Asahi Optical Co. Super Takumar 50mm f/1.4-16.0

Introduced with the original Spotmatic. Could not be used on earlier bodies due to the protruding rear lense element. earlier bodies could me modified by changing the original square aperture actuator to the curved type.
This lens does not yellow over time. [EDIT] Mine does, see pictures, Jens
Looking at Jen’s lens, I would have to say that it is the later S-T that does yellow. His serial number range looks correct however, the DOF scale is that of the later S-T. The original S-T’s IR marking is inside the F4 mark while the later is outside. Bob

    Very nice lens. it seem leica . Very pretty. And very good lens, too. Better, for my, than the seven elements. No castle. Gran definition. Great contrast. At F/ 5.6 and F/ 8 is really a summicron. At F/4 and F/11 is very, very good lens. So-so at F/1,4 (it’s not a planar). The changed to 7 elements
