S to C Mount Adapter

Some of Kodak's old 16mm lenses come in S mount (some in C mount). As far as I know, S mount is exclusive to Kodak. So only cameras made by Kodak can accept S mount lenses.

Fortunately, Kodak made adapters so that the lenses can be converted to C mount.

This is how a S mount lens looks like when it's converted to C mount with the adapter.
