When the Illuminas was first introduced they made sets for both S-16 coverage and S-35 coverage. There werte very few made & sold for 35 and all the ones now marketed are only for S-16. It's possible that the longer ones cover (the 50mm & maybe the 25), but don't count on it.
I have information from KMZ factory ( Russia ) , manufacturer of Optar Illumina lenses, and this technical informaton show, what lenses design for size 12.4 x 7.5 mm ( Super 16 ) only.
The factory informatrion not show any about S-35.
The is call lenses: ...... Optar-1.2 / 25 Optar 1.2/50, but,
the other information told name of lensesa ccording to russian classification of lenses with name ... OKS 3-25- F1.2/ 25 mm , OKS-15-50 F1.2/50 mm . and other.
This is second ifnormation tols about size of image 12.4x 7.5 mm only too.
I think, need set Optar lens on 35 mm cine camera and check size of image on film gate.
