Can anyone help? What's the proper progression of f-stops above f90? Is f128
next and tell a couple more if you have the info at your fingertips.
I've picked up a Finney Pinhole Bodycap for my Leica M. It's listed as a
30mm, approx. f128 and my Minolta meter goes to f90. So is f128 the next
f-stop in the natural progression of reciprocity? Twice as small? If not
someone please correct me!
Thanks for the help, Andrew Amundsen
