Reverse Ring for C-Mount Lens

The RICOH FP-RR27 is a reverse ring to mount lenses in reverse order for magnifying objects. The FP-RR27 is for 27mm filter sized lenses.

When a lens is used beyond its specified close-up distance, image quality may be deteriorated. By using a reverse ring, the deterioration can be minimized. The reverse ring is an accessory to mount the lens in reverse to magnify objects. 

Macro lenses are popular, but the combination of a C-Mount lens and the reverse ring may be a cost-saving solution for close-up applications with magnification of 1X or higher.
