Freewell 72mm Neutral Density 1.2 and Circular Polarizer Filter (4-Stop)

BH #FRFW72ND16PL • MFR #FW-72-ND16/PL
Freewell 72mm Neutral Density 1.2 and Circular Polarizer Filter (4-Stop)
Key Features
  • Magnetic ND Filter and Polarizer Filter
  • 16x Filter Factor, 4-Stop
  • Darkens Entire Image
  • Reduce Shutter Speeds, Widen Apertures
This Freewell 72mm Neutral Density 1.2 and Circular Polarizer Filter is a filter that combines a solid neutral density effect with a circular polarizer effect. When in use, this filter's 16x filter factor provides a 4-stop exposure reduction. Its 1.2 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily.

Freewell FW-72-ND16/PL Overview

This Freewell 72mm Neutral Density 1.2 and Circular Polarizer Filter is a filter that combines a solid neutral density effect with a circular polarizer effect. When in use, this filter's 16x filter factor provides a 4-stop exposure reduction. Its 1.2 density creates a darkening of the entire image, allowing you to photograph with a wider aperture or slower shutter speed than normally required. By slowing your exposure time or increasing your aperture, you are able to control depth of field and convey movement more easily.

Simultaneously, this filter can help 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.

An included Freewell 72mm Magnetic Quick-Swap UV Filter allows the neutral density and circular polarizer filter to be used on a lens with 72mm front filter threads. Each surface of the Freewell 72mm Neutral Density 1.2 and Circular Polarizer Filter and the Freewell 72mm Magnetic Quick-Swap UV Filter is multi-coated to help eliminate internal ghosting and reflections. The Freewell 72mm Neutral Density 1.2 and Circular Polarizer Filter and the Freewell 72mm Magnetic Quick-Swap UV Filter are also coated for resistance to oil, dust, and scratches, offering greater protection to the filters and helping them to stay clean for longer than with uncoated filters. The coatings are also hydrophobic, resulting in an improved beading effect when in contact with water for greater cleaning efficiency.

The Freewell 72mm Neutral Density 1.2 and Circular Polarizer Filter also includes 72mm front threads, permitting the use of screw-on filters with 72mm rear threads.

Freewell 72mm Neutral Density 1.2 and Circular Polarizer Filter

  • 1.2 neutral density filter effect darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required
  • Providing a 4-stop exposure reduction, this filter 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
