The ATHENA UV and IR Cut Rear PL Filter for ATHENA PL Mount Lenses from NiSi is a durable filter made from high-quality optical glass and designed to effectively block both ultraviolet and infrared light from your lens. Additional benefits include the maximization of visual clarity and color fidelity, especially in bright and outdoor environments. Its Multi Ti Nano coating offers low reflection and superior scratch resistance, especially aiding cinematographers working in dense/saturated settings from damaging their lens and filter. The item also includes a suction cap tool that allows for easy and clean filter changes on the go, eliminating the chances of fingerprints and smudges during swaps.
