SHD UV L39+H Round Filter:
•L39 Coating - Absorbs harmful UV Rays (<390nm) and minimizes haze
•Hardened Glass - Protects front lens element from damage better than ordinary filters
•HD Optical Technology - Provides an extremely flat optical surface for brilliantly sharp images with no ghosting •ULCA Multi-Coating - Decreases flare and significantly reduces chromatic aberration (average transmission >99.0% @ 420-680nm)
•NANO WMC Coating - Scratch-resistant multi-coating that repells water and oil making it easier to clean
•Black Coated Glass Edge - Prevents internal reflections and decreases optical flare
•CNC Matte Black Brass Ring - More resistant to side impacts, less likely to bind when placed onto a lens
•Slim Filter Ring Design - Reduces vignetting, keeps the profile of the filter more compact
