Kenko 72mm Celeste Circular-Polariser Filter

Coming from the Latin word "caelestis" that means magnificent, something above human possibilities and the Italian “celeste” which represents the color of the clear sky, the Celeste filter series promises the best optical performance and superior advantages to the photographer.

At the same time C-PL filter serves a good deal to protect expensive front optical element of the lens from physical damage.
