Circular Polariser for the Nisi S5 system.
This Nisi Polarizer filter is made of optical glass (Schott Glass) which makes it excellent for use with high resolution cameras and lenses. The filter is color neutral so that your photos will not show any color deviations and has a very low reflection. The filter is also provided with a Nano coating so that dirt and moisture do not adhere, making it very easy to clean and drops drop off immediately.
This polarization filter removes reflections and glare, so that colors and structures are reproduced faithfully. As a result, the filter ensures that water reflects less and the sky turns deeper blue.
