Alas, I have just acquired a wonderful set of Carl Zeiss Jena DF 7x40 military binoculars, but they lack enough focus travel to focus beyond about 20 feet for my nearsighted eyes. I am hoping to find some of the dioptric correction inserts for the eyepieces. As I recall, these used to be available for Fujinons. These DF's come equipped with yellow filters that insert into the present eyepieces, and those filters have an O.D. of 35mm, so anything close to that would work. I probably need anything from -2 diopter to -4 diopters of correction to reach infinity focus. Also, if you just happen to know a source of more information of this subject, please contact me!
