The ATHENA Full Spectrum FS ND 1.8 (6 Stop) Drop-In Filter from NiSi is specifically designed for use with NiSi Athena full-frame prime lenses. This neutral density filter reduces the amount of light hitting the sensor by 6 stops, allowing photographers to use longer exposure times and wider apertures. This is particularly beneficial in bright environments where overexposure must be avoided. The filter ensures full spectral neutrality, delivering authentic and vibrant images. Equipped with NiSi Optical Nano Coating technology, the filter offers additional protection against scratches and reflections. It is made from high-quality optical glass and housed in a lightweight yet robust aluminum frame, making it both durable and user-friendly. A convenient carrying case allows for easy and safe storage and transport of the filter.
