The first eight lenses and the stop move objectward as one unit by 23.9818 mm. DD15 increases from 2.9000 mm at infinity to 26.8818 mm at the patent's printed −0.5× near state. Intermediate spacings are calculated in inverse object-to-image distance rather than taken from a measured focusing cam. The printed near state gives a calculated object-to-sensor distance of 0.426 m with the physical plate train; Fujifilm specifies 0.43 m.
