Hi Scott,
I´d very pleased if you could explain me how do you
calculate this.
I know that f2 goes to 1,414 and then to 0,9999=1
Now lets calculate intermediate stops!!!
f2 goes to f1,80466 (The famosus Zuiko f1,8) and then to f1,60933
and then f1,414 and f1,27614 and f1.13807 and finally f1.00000!!!
So I think f 1,27614 is one 1/3 stop faster than Zuiko f1,4
isn´t it?
