Hoya HD Circular Polarizer Filter 82mm

Polarizing Filter Functionality

Polarizing filters selectively allow certain light rays to enter the camera lens by filtering polarized light. They effectively remove unwanted reflections from non-metallic surfaces such as water or glass and enhance color saturation to provide better contrast. The effect is visible through the viewfinder and can be adjusted by rotating the filter. The filter factor varies depending on the rotation and its orientation relative to the sun.

Applications

This filter is ideal for outdoor photography, such as capturing cloud-filled skies or enhancing the saturation of water bodies like oceans or lakes. It can increase or decrease reflections on water or glass surfaces, making it useful for shooting through windows or glass. When used in black and white photography, it can simulate dramatic effects such as an impending storm when combined with a red filter.

Alongside UV or Skylight filters, a polarizing filter is an essential tool for photographers aiming to transform ordinary images into vibrant, creative photos by increasing color saturation.

Technical Specifications and Features

• Constructed with hardened glass offering 4 times the tensile strength of traditional filters of similar fabrication.
• Incorporates special coatings to reduce internal reflections, enhancing image clarity, brightness, and sharpness.
• Provides 25% higher light transmission compared to standard polarizing films used in photographic filters.
• Eliminates ultraviolet rays to reduce haze in outdoor shots while polarizing light to remove reflections and increase color saturation without altering overall color balance.
• Enhances blue skies and makes clouds more prominent, especially when used at a right angle to the sun.
• Features an 8-layer multi-coating to minimize reflections on filter surfaces, reducing flare and ghosting.
• Water and oil repellent, scratch and stain resistant for durability.
• Meets ANSI standardized testing with 4 times the breaking strength, tested against steel balls dropped from 127 cm height.
• Compatible with cameras using beam splitters in the TTL light meter path and autofocus cameras.

Physical Characteristics
