HD MRC CPL Filter For Wide And Tele Lens 49mm 4.9cm Black

Helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface Polarizing filters arrange and filter directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light Clears up haze in distant landscapes and provides more saturated, vivid colors Strongest effect when used at a 90° angle from the sun Circular polarizers are ideal for use with digital cameras and autofocus lenses where a linear polarizer will often disrupt auto exposure and focus features 2x filter factor reduces exposure by 1 stop Constructed from Schott B270 glass for increased optical clarity and color fidelity Each glass surface includes 16 layers of anti-reflection coatings to prevent internal ghosting and reflections as well as to provide an improved beading effect when in contact with water or oil for greater cleaning efficiency Aluminum alloy filter ring assembly for durability while remaining lightweight Filter ring can be rotated to adjust the intensity of the polarization effect Polarizing filters arrange and filter directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of the light Strongest effect when used at a 90° angle from the sun
