The Formatt (Bogen) UV Haze 2B filter is a screw-in filter designed to absorb the invisible ultraviolet component of light, which often causes outdoor photographs to appear hazy or have a bluish cast, especially at high altitudes or near water.
UV Absorption: The 2B strength offers more effective UV reduction than standard Haze-1 filters.
Warming Effect: The filter has a slight yellow tint, which provides a warming effect to images.
Lens Protection: In addition to its optical benefits, it serves as a permanent protector for the front element of the lens against dust, moisture, and scratches.
Material: It is typically made from Schott-Desag B270 Crown Optical Glass.
Compatibility: This filter is for lenses with a 52mm filter thread size.
