Hoya HD Nano UV Filter 55 mm

Hoya HD Nano filters offer improved protection, performance and durability. They are essential gear for photography under extreme and severe conditions. HD Nano filters feature not only hardened glass but also an ultra-hard nano coating – to protect your camera's expensive lens from scratches and impact. This newly developed powder coating is stuck to the glass surface more firmly and closely on the nano level than formerly. The particles are layered on the glass surface with an extremely high density to create a hard smooth coating that is solid and scratch resistant. It also has superior water and oil repellent abilities to make filter maintenance easy and stress-free. Key features of HD Nano UV filters: Ultra-hard Nano Coating.
