I have a Cine-Ektar 25mm f1.9 S mount lens and a Cine-Ektar 15.. f2.5 S mount lens. My Kodak manual does not seem to give any information regarding filter sizes or lens cap sizes. The only information is to use adapter rings of a certain number, but number seems to be a propitiatory number that has no relationship to filter size. Cinematography.com community is the site where dumb questions can get wise answers, so my question is: What is the filter size for each of these lenses? Also, while the lenses themselves sit deep in the lens mounts, I would like to put a lens cap on each lens when camera or lens is not in use.So what size lens cap would I use for each of these lenses?
cine ektar filter sizes
