Hi,
I am new here but have been reading threads here. I just got a lens of Schneider G-Claron 210mm f/9. The thing is, I just have a compur # shutter with max aperture of f/5.6, and I don't have the exact correlations or converting matches between the real aperture of the aperture showing on the shutter. By roughly comparing, it seems a one-stop correlation that 5.6-9, 8-11, so and so on. But I am not sure whether I am correct and wondering if there is any strict formula or table to follow. Thanks, guys.
