Circular polarizer ND 77mm Hoya

The 77 mm UV and IR Cut Filter from Hoya is a lens filter that, when attached to your lens, permits only the visible spectrum of light rays to enter the camera and get captured by the sensor. It blocks out both the higher frequency ultraviolet rays, and lower frequency infrared light rays. This is important to digital photographers because the CCD and CMOS sensors found in our cameras are extremely susceptible to catching UV and IR rays just outside the visible spectrum that have a very negative impact on image quality.
