I have a second type biotar 58mm with a semi bad rear group. I wonder if I could mount the front group, or simply the front lens, on the first type postwar biotar (17 blades)
AFAIK it is te very same optical scheme.
both are M42.
The 17 blades would make a better lens but it features a bad front lens.
same as te two lenses talked about here
