The X-Series Protector Filter from Zuma fits lenses with a 77mm filter thread, adding a layer of protection and helping prevent damage to the surface of the lens, or to the metal edges of the lens if it is dropped or impacted by another object. Made of optical glass, this filter has 16 layers of multi-coating to prevent unwanted reflections, and neutral color rendering. Using a protector filter provides the desired added protection without having any effect on color.
The slim filter ring prevents vignetting when used with wide-angle lenses and features front threads for adding additional filters or accessories. It has top knurling to easily grip for screwing on and off the lens.
