Schneider 77mm Neutral Density 0.9 Circular Polarizer Filter (3 Stops)
Key Features
  • 8x Filter Factor, 3 Stops
  • Darkens Entire Image
  • Allows Reduced Shutter Speed
  • Allows Wider Aperture
The Schneider 77mm Neutral Density 0.9 Circular Polarizer Filter is a filter that combines a solid neutral density effect and a circular polarizer effect. The solid neutral density effect provides an exposure reduction of 3 stops. Its 0.9 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than would normally be required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily.

Schneider 68-016177 Overview

The Schneider 77mm Neutral Density 0.9 Circular Polarizer Filter is a filter that combines a solid neutral density effect and a circular polarizer effect. The solid neutral density effect provides an exposure reduction of 3 stops. Its 0.9 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than would normally be required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily.

Along with this filter's solid neutral density effect is a circular polarizer effect that is simultaneously applied to help 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 77mm Neutral Density 0.9 Circular Polarizer Filter is constructed from water white glass for increased optical clarity as well as color fidelity and features an anodized, aluminum-alloy filter ring that can be rotated in order to adjust the intensity of the polarization effect.

0.9 neutral density filter effect darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required and is combined with a circular polarizing effect to help reduce reflections and glare by filtering out light that has become polarized due to reflection from a non-metallic surface
8x filter factor provides a reduction of 3 stops; neutral density filter effect allows you to control depth of field and convey movement more easily
Polarizing filter effect arranges, and filters, 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 polarizing 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
Constructed from water white glass for increased optical clarity
Each glass surface includes multiple layers of anti-reflection coating to prevent internal ghosting and reflections
Anodized, aluminum-alloy filter ring for durability while remaining lightweight
Thin filter ring helps to prevent vignetting
Filter ring can be rotated to adjust the intensity of the polarization effect
77mm front filter threads allow for use with other filters
Padded pouch included for storage and transport
