Overview
  • 1Description

The Hoya 77mm Circular Polarizer Super-HMC Thin Filter 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.

This filter features a seven-layer Super-HMC multi-coating, which helps to reduce internal flare and reflections. Thin filters are specifically designed for use with wide angle lenses and do not have front threads for stacking additional filters.

Clears up haze in distant landscapes and provides more saturated, vivid colors.
Strongest effect when used at a 90° angle from the sun.
Seven-layer multi coating helps to minimize internal reflections and ghosting and maintain an overall neutral color balance.
Thin mount filter ring helps to prevent vignetting when used on wide-angle lenses.
