I haven't been able to find a table of equivalencies. Well, these are what they say they are: that is, f/12.5 is one-third of a stop between f/11 and f/16, while f/6.3 is one-third of a stop from f/5.6 to f/8. The one-third stop is easily accomodated by all films today save for some of the pickier technical emulsions and some chromes.
