I am choosing between 2 different Industar-61 L/D lenses to purchase, where one has a serial number corresponding to 1985, and the other has a serial number of 1993.
I was wondering if there are any differences in lens character or quality control in the Industar-61 L/Ds as the years went on? Did production quality increase as time went on or decrease; would the '85 or '93 model be likely to have better quality, or would there be negligible difference in the two? The '93 model is half the price of the '85 model, fwiw..!
