Hi Gang.
I used the Sinar for the first time today and I noticed that my Rodenstock Sironar 135mm f-5.6 lens has 2 lines of f-stops numbers. The first line reads f-135mm 5.6, 8, 11, 16, 22, 32, 45, 64 these numbers are in white. The second row of numbers are in yellow and read f-400 16, 22, 32, 45, 64. Can anybody enlighten me on the meaning of these numbers.
Thanks.
Louie
