Show More
The 39mm Circular Polarizer HD MC Filter from H&Y Filters helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges and filters this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.

H&Y Filters MPL39 Overview

The 39mm Circular Polarizer HD MC Filter from H&Y Filters helps to reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface. The light from the sun naturally becomes partially polarized due to reflecting off electrons in air molecules, causing the light to scatter into what appears as haze. A polarizing filter arranges and filters this directionally polarized light perpendicularly to the reflected light, allowing for the absorption of much of this light. This results in a noticeable reduction of glare and reflections from non-metallic surfaces and an increase in the saturation of skies and foliage.

A circular polarizer only differs from a linear polarizer in that it contains a quarter wave plane in addition to the linear polarizing filter. The addition of this quarter wave plane is to circularly polarize the linearly polarized light for the use of auto focus and exposure functions. Due to how the light is broken down and filtered with a linear polarizer, auto focus and exposure accuracy become skewed during use. When the light becomes circularly polarized, it permits the use of these functions.

The 39mm Circular Polarizer HD MC Filter is constructed from Schott B270 glass for increased optical clarity and color fidelity. Each side of this filter includes 16 layers of 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. It also features an aluminum alloy filter ring that can be rotated in order to adjust the intensity of the polarization effect.

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
