The f/stops on the 85/1.4GM are a bit weird:

In one-third stop increments, it should go:

1.4, 1.6, 1.8 and 2

However, with the GM, it goes:

1.4, 1.6, 1.7 and 2

f/1.7 belongs to the one-half-stop f-number scale...


Just mounted my 35/1.4, it has same aperture steps as 85/1.4

Btw, in doing so, found best reason to try 85GM....
The 35/1.4 now seems small and light to me!


Found that someone somewhere calc\'d exact f stop vals, so you can see actuals (and showing your point is correct)
1/3 steps:
1.414
1.587
1.782
2
2.245
2.520
2.828
