Hoya 58mm alpha Circular Polarizer Filter
Key Features
  • Circular Polarizer Filter
  • 3 to 4x Filter Factor, +1.6 to 2 Stops
  • Helps to Eliminate Reflections and Glare
  • Reduces Haze in Landscapes
The Hoya 58mm alpha 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. 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.

Hoya alpha Overview

The Hoya 58mm alpha 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. 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 is non-coated and has approximately 96% average light transmission. It is constructed from optical glass and precision milled aluminum frames.

What is the difference between a circular and a linear polarized filter?
Asked by: James
Circular polarized filters work with in camera metering and auto focus and helps with reflecting light such as on snow, sand, glass, etc. Linear filters don't function quite properly with these similar systems in modern cameras.

question

will this fit tamaron 24 to 70mm lens?
Asked by: Anonymous
The Tamron 24-70mm f/2.8 VC lens has an 82mm filter thread, so the Hoya 58mm alpha Circular Polarizer would be much too small. You would need the Hoya 82mm alpha Circular Polarizer filter (B&H # HOCPA82).
