Double sides polishing for maximum resolution and quality. Optical glass filter image quality definition is much higher than resin filter. | 【28 Multi-Layer Coatings】Both sides of filter glass with nanometer coatings are waterproof, and scratch-resistant, effectively preventing the reflection both coming from the filter and the ground, with no color cast for the photos. | 【Metal Filter Holder】Allows creative use of light correction or special effects.
