The listings include two filters: a neutral density IR filter (ND16 IR) and an ultraviolet (UV) filter.
The filters are shown in 49 mm and 37 mm thread diameters.
The ND16 IR filter reduces infrared light, helping prevent overexposure and enabling motion-blur effects. The UV filter cuts haze, reduces reflections, and helps neutralize color to improve contrast and clarity.
They act as a protective barrier for the lens, and their coatings and construction add water, oil, dust, and scratch resistance.
Yes. The filters use an ultra-slim frame to minimize unintended vignetting, and a multi-threaded design allows stacking multiple filters.
The coatings are described as water resistant and oil resistant; the UV option is also noted as dust resistant and scratch resistant.
The listed overall dimensions range approximately from 3.5 x 0.9 x 3.9 inches to 3.6 x 0.9 x 3.7 inches, and weights range from about 0.12 to 0.16 pounds.
