Hi folks
here there are 3 super takumars 50.14 , first is a eight elements: infrared mark is at right side of number 4, it has "M" and "A" and it has not any yellowish tint.
third is a normal 7 elements : infrared mark is on the left side of number 4, "MANUAL" and "AUTO", it has a yellowish tint and it has a withe dot near 1.4
In the midle of both ther is a rare one: infrared mark is on the left side of number 4 , IT HAS "M" and "A" , it has a yellow tint and it has not the dot near 1.4, the rear element protrusion is bigger than the eight elements
what is it ? is it rare a radioactive 8 elements or not?
thanks
