NiSi Square Filter, HD Polarizer (CPL) 100x100mm

NISI Square Optical Glass HD Polariser Filter 100x100 * Ultra Low Color Cast, Ultra Low Reflection * High Definition * Ultra-thin frame design * Nitto original polarizing material * Blackened glass edge technology * Black fine grinding frame * Advanced frame embossing technology CPL polarizer is also called polarizer, is the abbreviation Circular Polarizer. Mainly used to suppress non-metallic surfaces highly reflective (polarized), revealing the original color and texture of the object, can also be used to improve the tone and hue of the sky, most commonly used filter especially in landscape photography, for digital its role is irreplaceable. CPL structure is sandwiched in the middle two pieces of a polarizing optical glass glued together, nisi HD CPL polarizing film imported from Japan, low color shift, and optical precision double-sided glued and then polished to achieve an excellent level and parallelism, to provide the best image quality.
