NiSi Filter Protector Pro Nano HUC 37mm beskytter dit objektivs frontlinse mod støv og stød, samtidig med at den bevarer høj optisk ydeevne. Den bruger højkvalitets optisk glas med nano-coating på begge sider, hvilket tillader >99,3% lysgennemgang. Samtidig er filterets ramme lavet af højkvalitets aluminium og måler kun 3,5 mm i tykkelse, hvilket hjælper filteret med at passe selv på supervidvinkelobjektiver og reducerer risikoen for vinjettering.
For det første bevarer det billedkvaliteten ved at transmittere over 99,3% af det indkommende lys og holde overfladereflektioner omkring 0,3%. For det andet hjælper den ultra-tynde 3,5mm aluminiumsramme med at forhindre vinjettering, når det bruges på vidvinkelobjektiver. For det tredje gør nano-coatings og den hærdede vandtætte lag rengøringen enkel og tilføjer et niveau af fysisk beskyttelse til daglig brug.
