I don´t know two different optical formulas on this lens 50mm f 1.4.
>From the first times Olympus made this lens with 7 elements / 6 groups.
I´m I wrong ?
Joseph, what is the difference from one formula to other ?
Are you talking about the two different formulas of the 50mm f 1.8 ?
1ª 6 elements / 5 groups.
2ª 6 elements / 4 groups.
Or are you calling "different optical formula" the different coating
treatments ?
