Sigma AFL-940 46mm EX DG UV Multi-Coated Filter
Protect your camera lens from dust, moisture, and scratches with the Sigma AFL-940 46mm multi-coated filter. Sigma filters add durability to your lens, while also correcting for ultraviolet light, which can register on film and videotape as a bluish cast and can obscure distant details. In addition, you can leave the filter on the lens at all times for maximum protection. The filter, which fits lenses with 46mm threads, is particularly helpful for mountain and marine environments, where increased haze threatens to make your photographs indistinct in color and clarity.Technical SpecificationsType: UltravioletSize: 46mmFilter factor: Not applicableMulti-coated: YesRotating: Not applicableEffect: Reduces excessive blue, cuts through haze, improves image clarity, protects front element of lensApplications: Ideal for mountains and marine settingsColor temperature: No changeConstruction: GlassThread size: 46mmFront lens cap size: 46mmWarranty: 1 year
