How many versions of the 60mm V mount lens are there?.
Distagon f/5.6 60 mm C
Distagon f/4 60 mm C small production run no T* AFAIK
Distagon f/3.5 60 mm C and T* version
below all are T*
Distagon f/3.5 60 mm CF
Distagon f/3.5 60 mm CFi
Distagon f/3.5 60 mm CB
AFAIK there was no E - electronic databus version or F version although that is not strictly true there was a 60mm f5.6 for the 1600F, 1000F bodies (1948-57) and there was also a 60mm f/5.6 MK Biogon for the MK70.
You could keep yourself well occupied just collecting all those variants
I have no hands on experience with any but I'm actively looking for a f3.5 C uncoated, just into non T* look at the moment.
