The 55 mm URPRO Green (GR) filter utilizes URPRO's patented color-correcting technology.  This filter is ideally suited for fresh or salt water that is green in appearance due to a high abundance of algae in the water.  The coastal waters of the Mediterranean are an excellent candidate for the GR filter. All URPRO filters sold by SRP feature an ultra low-profile filter ring in order to limit mechanical vignetting.

Note: Camera and filter adapter not included.
