Nikon CP-4 polarizing filter
Does anyone know the front-thread specifications for an older Nikon CP-4 polarizing filter? It has 52mm rear threads, but the front diameter is larger -- maybe 59mm or 60mm?. If possible, I'd like to mount it in the infinity space between a Raynox DCR 150 and a Nikon Plan 10X infinity microscope objective.
