I have an old portrait lens that I want to use. It came with a set of torn paper disks with verious size holes, apparently to be used as f-stops as there is no iris. The front of the lens unscrews to get at the set and select one for use. M y guess is that I'll be using the lens wide open, but I'd like to make a new set of stops as well. Can anyone suggest what paper to use? Or would they be better if made from thin plastic of some kind? Should I duplicate the stop diameters or should I try to calculate new ones? If so, how would I do it? Any suggestio ns would be helpful. Thanks in advance.
