• Helps to Eliminate Reflections and Glare
• Reduces Haze and Blue Cast in Landscapes
• Greater Color and Tonal Saturation
• Optical Glass and Aluminum Filter Ring
The Polaroid 77mm Circular Polarizer Filter helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. This results in a noticeable increase in the saturation of skies and foliage, as well as clearer imagery when photographing in hazy conditions. A circular polarizer differs from a linear polarizer in that it supports full use of a camera's autofocus and auto exposure functions.
This filter is constructed from optical glass and features an aluminum filter ring to provide increased rigidity and as well as resistance against expansion or contraction due to temperature variances.
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° from the sun.
